TFT Patch 18.4 Notes: Solar Reroll and Lunar Buffs

Solar reroll is back on the table. Here is our read on every trait, unit, augment and Wisp change in TFT Patch 18.4, plus the 7 October mid-patch update.

By the MID.GG editorial team

Patch 18.4 9 October 2026 16 min read

Teamfight Tactics patch 18.4 takes power away from Emblem-reliant verticals and easy frontlines and hands it to low-cost reroll lines. Solar reroll gains the most. Executioner, Juggernaut, Veigar, Kennen and Ashe are nerfed, Lunar, Blossom and Sprykin get stronger deep breakpoints, and a 7 October 2026 mid-patch update tops up several weak 1- and 2-costs.

TL;DR

Solar reroll returns: Xayah, Rakan, Varus, Kayle and Shen are all buffed. The mid-patch update also gives Varus more starting mana.
Executioner and Juggernaut are nerfed: Executioner (4) held a 73.2% top-4 rate and Juggernaut (6) held 61.0% before the patch. Expect both to drop, not vanish.
Deep verticals are buffed: Lunar, Blossom, Sprykin, Riftbeast and Eclipse all gain power. Elderwood and Coven get mixed changes.
Top 5-costs come down: Kennen and Ashe are nerfed. Ivern and Lux are adjusted.
Emblem lines lose power: Elderwood Emblem, Fae and the Prismatic Trait Ladder are all nerfed.

Full changes in Teamfight Tactics patch 18.4

The cards below cover the main patch first, then the 7 October mid-patch update. Earlier patches live on the TFT patch notes hub.

Mid-patch update

Good to knowMid-patch update: 7 October

The B-patch fixes bugs, disables performance-heavy Arenas, stops some trait augments from appearing too often and corrects two Wisp costs, alongside targeted balance changes. This adjusted update is targeted rather than sweeping. It tops up weak 1- and 2-costs and pulls Heart of Steel for now, so re-check your econ augment habits before queuing.

1 cost unit

Ability Damage: 150/225/375 ADchanged to 150/225/400 AD

MID.GG analysis

This second buff to her 3-star damage stacks with the main patch. She sat at a 34.4% top-4 rate before the patch, so she stays a low-priority reroll until results improve.

Mana: 30/120changed to 20/110

MID.GG analysis

With more starting mana and less max mana, Varus casts sooner. Combined with his attack speed buff, he is the most improved Solar reroll 1-cost.

2 cost unit

Heal: 200/260/320 APchanged to 230/300/400 AP
Spell Damage: 100/150/225 APchanged to 180/270/420 AP

MID.GG analysis

His spell damage rises sharply and his heal grows, which turns Alistar into a frontline that also threatens kills. That matters for 2-cost reroll boards that need a tank who contributes damage.

AP Form Splash Damage: 160/240/375 APchanged to 180/270/435 AP
AD Form Base AD: 45changed to 50
AD Form Attack Speed: 0.7changed to 0.75

MID.GG analysis

Both forms gain power on top of the main-patch buff. That makes Gromp a flexible 2-cost you can slot into AD or AP boards without losing much.

Empowered Attack Damage: 60/90/135 ADchanged to 65/100/160 AD

MID.GG analysis

The empowered attack gains the most at 3-star. That favors players who reroll Murkwolf rather than using him as a stage 2 filler.

Spell Damage: 215/325/500 ADchanged to 230/345/535 AD
Spell Healing: 20%changed to 25%

MID.GG analysis

More damage and more healing help a unit that held a 44.9% top-4 rate before the patch. He becomes a more reasonable 3-star target in low-cost reroll lines.

3 cost unit

Base AD: 55changed to 60

MID.GG analysis

Extra base AD adds to her ability buff and makes a Riftbeast reroll line around her worth testing.

4 cost unit

Note: Nidalee Armor Penetration matches Tooltip (as per 18.3 fix)

MID.GG analysis

This adjusted entry is a bug fix: her armor penetration now matches the tooltip, following the 18.3 fix. Expect no meaningful power shift from it.

Wisps

Armor and MR Boost: 10changed to 8, Attack Speed Boost: 8% ⇒ 6%

MID.GG analysis

The nerf lowers the armor, magic resist and attack speed these give. Generic stat rolls become a weaker default.

Explosion Damage: 12%changed to 15%

MID.GG analysis

The explosion deals more damage, which rewards boards that trade kills quickly in dense fights.

Mana Reduction: 25/18%changed to 20/15%

MID.GG analysis

This mid-patch buff changes its mana reduction values. Consider it when a carry needs one early cast to swing the fight.

Cost: 3/1gchanged to 1/0g

MID.GG analysis

The buff corrects its cost downward, so it is an easy pickup on low-gold rolls.

Note: 9gchanged to 10g

MID.GG analysis

This buff is listed as a cost correction from the mid-patch fix. Treat it as a price change rather than a new reason to roll for it.

Augments

Buff Duration: 3schanged to 4s

MID.GG analysis

A longer buff duration helps backline carries that need sustained uptime to finish fights.

Health: 200changed to 225

MID.GG analysis

Extra health helps frontline-heavy boards, especially now that Juggernaut is nerfed.

Resists: 6changed to 7

MID.GG analysis

One more point of resists is a small buff. It slightly favors wide boards that spread the bonus.

Resists: 9changed to 10

MID.GG analysis

A small resist buff makes it a little safer on tank-heavy reroll boards.

Initial Gold: 4gchanged to 6g

MID.GG analysis

More initial gold makes this buff more attractive on stage 2 econ starts.

AD: 9%changed to 11%
AP: 10%changed to 11%

MID.GG analysis

Higher AD and AP make it a cleaner combat augment for boards that keep a single row of tanks.

Heal: 7.5%changed to 9%

MID.GG analysis

A larger heal helps sustain-reliant frontlines win long fights.

Baseline AD/AP: 5%changed to 3%

MID.GG analysis

The nerf trims its baseline AD and AP, so its value now leans on the leveling side rather than combat stats.

Damage By Stage: 30/50/70/90changed to 25/40/60/80

MID.GG analysis

The damage cut at every stage makes it a weaker pick for tanky frontlines that took it for free damage.

Gold: 8changed to 5

MID.GG analysis

With less gold, this Silver augment is a slower econ pick. Favor it only when you plan to play for the late game anyway.

Systems

Riot’s reasoning
Cutting 2 seconds from every fight saves close to a minute each game.

Note: Reduced Combat Arrival and Combat Departure phase times by 1 second each

MID.GG analysis

This adjusted rule shortens every round slightly, leaving less downtime between fights to scout and plan positioning.

Traits

Riot’s reasoning
Blossom works well as a splash for upgraded Wisps, but its deep breakpoints are underexplored, so (7) and (9) gain more stats.

AD/AP: 12/30/45/50%changed to 12/30/50/55%

MID.GG analysis

Blossom (7) sat near average at a 53.4% top-4 rate. This buff gives the vertical a real reason to exist beyond the splash.

Riot’s reasoning
Eclipse comes online too late in fights and its first executes on low-health targets lack impact, so the delay before execution is shorter.

Initial Delay before execution: 10schanged to 8s

MID.GG analysis

Eclipse already held a 73.5% top-4 rate on a tiny pick rate, so this buff makes a rare activation even more decisive when you hit it.

Riot’s reasoning
Few players go deep into Lunar, so its higher breakpoints gain AP, which also makes Lunar Lux more appealing.

Ability Power: 7/10/14/18%changed to 7/12/16/20%

MID.GG analysis

Lunar (4) already held a 73.1% top-4 rate on a pick rate under 1%. This buff makes Lunar Lux boards a real target rather than a surprise.

(7) AD/AP/Attack Speed every 5s: 5%changed to 6%

MID.GG analysis

The (7) buff supports a Mama Beak reroll line. Riftbeast (7) sat near average at 51.4%, so it needs testing before it earns a spot.

Riot’s reasoning
Sprykin (7) needs an Emblem and a 5-cost to hit yet underperforms, so its BFF bonus grows, and at (7) that bonus reaches every Sprykin.

(7) Stats: 45% HP + 45% ASchanged to 55% HP + 55% AS

MID.GG analysis

Sprykin (7) already held a 64.8% top-4 rate on a small sample. The buff rewards players who find the Emblem early.

(3/4) Bleed Damage: 30/40%changed to 25/35%

MID.GG analysis

The bleed nerf hits the (3) and (4) breakpoints, which held 62.8% and 73.2% top-4 rates. Executioner should stay viable, but Emblem-stacked carries lose their edge.

Riot’s reasoning
Fae relies too heavily on its Emblem, so trait power moves into buffs for three Fae units.

AD/AP Per Pixie: 5/8%changed to 4.5/7%

MID.GG analysis

The nerf hurts Emblem-first Fae boards, while Xayah, Rakan and Tristana carry more of the power themselves.

Riot’s reasoning
Juggernaut (6) is too easy to hit and flex for the frontline it provides.

Juggernaut Durability: 20/33/45%changed to 20/30/42%

MID.GG analysis

Juggernaut (6) held a 61.0% top-4 rate, so this nerf lowers the floor of the default frontline. Look to Spirit Visage tanks or other traits to fill the gap.

Riot’s reasoning
Coven’s Stage 2/3 cashout at 130 essence is too consistent for a cashout trait and beats the other Coven lines, so its rewards drop.

130 Cashout: 2x Componentschanged to 1x Component + 6 gold
130 Cashout: 1x Component + 2★ Elise + 1★ Cassiochanged to 1x Component + 2★ Elise
130 Cashout: 1x Random Itemchanged to 1x Component + 2★ Camille + 3g
130 Cashout: 2★ Caitlyn + 1x Component + 3gchanged to 2★ Caitlyn + 1x Component

MID.GG analysis

These mixed changes push Coven players away from the early cashout. Coven was already struggling, with Coven (5) at a 31.2% top-4 rate, so play it only when the trait falls into your lap.

Riot’s reasoning
Elderwood (7) leans on Emblems, so with Emblem lines coming down the Deepwood Protector gets stronger while Elderwood (9) takes a small net loss.

(7) Deepwood Protector Mana: 20/70changed to 20/60
(7) Deepwood Protector Resists: 65changed to 70
(9) Health Multiplier for Elderwood Plants starring up: 155%changed to 140%

MID.GG analysis

These mixed changes favor Elderwood (7) boards that never find the ninth unit. Elderwood (9) at 87.8% is too small a sample to chase deliberately.

1-cost units

Riot’s reasoning
Camille has been conditional since last patch’s nerf, so her 3- and 4-star damage rises.

Damage AD: 150/225/375/640changed to 150/225/400/665

MID.GG analysis

The buff only pays off when you hit 3-star. She remains a speculative reroll after a 34.4% top-4 rate.

Riot’s reasoning
Kobuko mostly appears as a Blackthorn sacrifice for tank stats, so a better AP ratio aims to make him worth itemizing.

Heal AP: 265/315/460/575changed to 285/335/480/595

MID.GG analysis

The healing buff helps AP-itemized Kobuko frontlines. He is still a niche pick outside Blackthorn boards.

Riot’s reasoning
Rakan and Xayah gain ratio buffs, amplified by Fae stats, to give Rakan item value and revive their Solar reroll line.

Shield: 270/320/415/490changed to 290/340/435/510

MID.GG analysis

A bigger shield makes Rakan a worthwhile item holder in Solar reroll. That matters most when you pair him with Xayah at 3-star.

Riot’s reasoning
Xayah and Rakan gain ratio buffs, amplified by Fae stats, to revive their Solar reroll line.

Ability Damage: 68/102/155/165changed to 73/108/165/175

MID.GG analysis

Xayah is the main carry the Solar buffs target. Her 43.9% pre-patch top-4 rate leaves room to rise, but it is too early to call her a top comp.

Riot’s reasoning
Varus has underperformed all set, so extra attack speed lets him cast more often and smooths out his missed casts.

Attack Speed: 0.7%changed to 0.75%

MID.GG analysis

With the mid-patch mana buff on top, Varus is the 1-cost most likely to gain in Solar reroll.

Riot’s reasoning
Veigar was the strongest 1-cost reroll in 18.3, so his damage drops to demand stronger starts and specific Artifacts.

Ability Damage: 200/300/450/765changed to 190/285/430/725
Low HP Ability Damage: 300/450/675/1015changed to 285/430/640/1000

MID.GG analysis

The nerf hurts low-roll Veigar games most. Commit to him only off a strong stage 2 or a fitting Artifact.

2-cost units

Riot’s reasoning
Gromp’s AD form casts too slowly and its AP form’s splash is too low, so both get help.

Mana AD Form: 20/80changed to 0/70
Splash damage AP Form: 160/240/360/610changed to 160/240/375/625

MID.GG analysis

The AD form now starts with no mana and casts faster, which makes AD Gromp a real reroll option.

Riot’s reasoning
Kayle and Shen get smaller buffs to support Solar and other low-cost reroll lines that were nearly missing last patch.

Ability Damage: 62/92/105/115changed to 65/97/110/115

MID.GG analysis

The buff is small and mostly helps Solar boards. Her 45.7% top-4 rate suggests she remains a support piece rather than a carry.

Riot’s reasoning
Shen and Kayle get smaller buffs to support Solar and other low-cost reroll lines.

Shield: 350/430/550/700changed to 375/450/575/725
Ally Shield: 200/275/375/475changed to 225/300/400/500

MID.GG analysis

Larger shields for himself and an ally make Shen a sturdier Solar frontliner, which helps the 1-cost carries survive to their cast.

AOE Damage: 55/82/130/215changed to 55/82/155/240

MID.GG analysis

The buff lands only at 3- and 4-star. It rewards Teemo reroll and does little for him as a filler.

3-cost units

Mana: 30/110changed to 50/110

MID.GG analysis

More starting mana means Hecarim casts sooner. That helps him engage before the enemy backline fires.

Riot’s reasoning
Mama Beak is used as an item holder but never as the reroll star, so her 3-star damage rises alongside a Riftbeast (7) buff.

Ability Damage: 22/30/48 ADchanged to 22/30/52 AD

MID.GG analysis

Reroll players get a new 3-cost line to test. Her role as a holder for Aphelios and Draven items stays intact.

Riot’s reasoning
Three-star Rammus stalls fights long enough for Azir and Zyra to clean up, so his 3-star shield drops.

Shield: 400/550/725 APchanged to 400/550/700 AP

MID.GG analysis

The nerf touches only 3-star, so Azir and Zyra boards lose a little stall time but keep their core.

Riot’s reasoning
Rengar falls off too fast to justify rerolling for 3-star, so his 3-star damage rises.

Ability Damage: 255/385/615 ADchanged to 255/385/650 AD

MID.GG analysis

The buff matters only if you commit to 3-star. It feels best when Rengar has stacked plenty of takedowns.

Riot’s reasoning
Tristana is the third Fae unit to gain power moved out of the trait.

Ability Damage: 160/240/385 ADchanged to 175/265/420 AD

MID.GG analysis

Higher damage makes her a better standalone carry while Fae itself is nerfed. She starts from a low 45.3% top-4 rate.

4-cost units

Riot’s reasoning
Brambleback’s leap is inconsistent, so power shifts from the leap into his more reliable cast for fights where he is stuck on a tank.

Ability Bonus AD: 80% ADchanged to 100% AD
Leap Damage: 155/235 ADchanged to 135/205 AD

MID.GG analysis

These adjusted numbers smooth out his bad fights against big frontlines at the cost of some backline burst.

Riot’s reasoning
With Executioner coming down, Ezreal gets a small buff so his success depends less on Executioner Emblem carries.

Small Cast Damage: 250/375 ADchanged to 270/405 AD

MID.GG analysis

He suits fast 8 AD boards that cannot find Executioner Emblems.

Riot’s reasoning
AP Nidalee gains damage to add an AP carry for fast 8/9 boards, while AD Nidalee loses damage for dominating mid-game fights.

AP Form: Small Spear Ability Damage: 170/255 APchanged to 185/275 AP
AD Form: Ability Damage: 210/315 ADchanged to 200/300 AD

MID.GG analysis

These mixed changes point you toward the AP form on leveling boards. AD Nidalee takes a slight hit in the mid-game.

Ability Damage: 190/285 ADchanged to 200/300 AD

MID.GG analysis

A modest damage buff helps AD fast 8 boards that use Sivir as a secondary carry.

5-cost units

Riot’s reasoning
Ashe gains a mana refund when her arrow misses, and because she was already a top 5-cost her unitemized damage drops.

Note: NewNow refunds 70% Mana if the arrow hits 0 enemies
Mana: 20/80changed to 0/80
Percent Health Damage: 2/3%changed to 1.5%

MID.GG analysis

This nerf mainly hits Ashe as a 1-star drop with no items. Itemized Ashe, who held a 63.1% top-4 rate, should stay strong.

Riot’s reasoning
Draven gains a mana refund on missed axes and a better bleed ratio because he has struggled as a carry since his bounty nerf.

Note: NewNow refunds 50% Mana if the axes hit 0 enemies
Bleed Damage: 140/210 ADchanged to 150/225 AD

MID.GG analysis

This buff makes Draven a more reliable late-game carry. Mama Beak boards that hold his items benefit most.

Riot’s reasoning
Damage amp scales multiplicatively with AD, AP and crit, so Mushroom hexes lose power while Rock hexes gain resists to match Tree hexes.

Greenfather Hexes: Damage Amp: 8/12%changed to 6/10%
Greenfather Hexes: Bonus % HP: 8/12%changed to 6/10%
Greenfather Hexes: Resists: 8/12changed to 10/14

MID.GG analysis

These mixed changes shift Ivern’s value toward tankier hexes. That slightly lowers the damage ceiling of the boards around him.

Riot’s reasoning
Kennen ramps too hard at 2-star as enemies burn, so his shield’s AP ratio drops to make him easier to kill.

Shield: 250/350 APchanged to 230/300 AP

MID.GG analysis

The nerf makes Kennen easier to focus down, but he held a 64.6% top-4 rate. Edge of Night remains one of his best items.

Riot’s reasoning
Solar Lux is rarely worth fielding, so her Solar bonus changes to make her the highest-damage Lux variant.

Solar bonus: NewDeal 15% bonus damage. For each unique 3-star champion fielded, deal an additional 12% damage.

MID.GG analysis

This adjusted bonus rewards boards with several unique 3-star units. That makes Solar Lux a strong cap for reroll even outside full Solar.

Items

Riot’s reasoning
Crownguard is the best tank item on the units that can build it, so it gives less AP when the shield expires.

Bonus Ability Power On Shield Expire: 25changed to 20

MID.GG analysis

The nerf trims value from AP tanks that relied on it. Expect Spirit Visage to take some of its slots.

Riot’s reasoning
Spirit Visage is the weakest tank item despite its flexibility, so it gains durability.

Durability: 8%changed to 10%
Radiant Item Durability: 15%changed to 18%

MID.GG analysis

The buff makes it a cleaner default tank item, which matters now that Juggernaut’s durability is nerfed.

Emblems

Riot’s reasoning
Elderwood Emblem is already strong, so it loses resists as Elderwood (7) itself gets stronger.

Resists: 35changed to 25

MID.GG analysis

The nerf lowers the value of slamming Elderwood Emblem on a carry. The trait now carries more of the power.

Augments

Starting Health: 1000changed to 1500

MID.GG analysis

A sturdier dummy buys more time for backline carries. The buff favors reroll boards that need to stall.

Max Health Gain: 16changed to 18

MID.GG analysis

It is buffed on paper, but the 7 October mid-patch update disables it for now, so you will not see it until it returns.

Max Health per Interest: 8changed to 9
Initial Gold: 4changed to 6

MID.GG analysis

More initial gold and more max health per interest make this buff a safer econ pick for players who sit on gold.

Max Health per Interest: 10changed to 12
Gold Granted: 8changed to 10

MID.GG analysis

The buff improves both the gold and the health, so it suits greedy fast 8 games.

Instant XP: 6changed to 10

MID.GG analysis

Much more instant XP makes this buff a strong opener for players who plan to fast 8.

Gold Granted: 3changed to 5

MID.GG analysis

More gold granted makes this buff an easier pick for flexible players.

Effectiveness: 35%changed to 45%

MID.GG analysis

Higher effectiveness makes this Gold buff a better pick for Yordle-friendly boards that field small units.

AD/AP per Ally: 2%changed to 2.5%

MID.GG analysis

More AD and AP per ally rewards deep verticals like Lunar and Blossom, which fits this patch’s direction.

AD/AP per Ally: 3.5%changed to 4%

MID.GG analysis

The Prismatic buff pairs well with the deep trait buffs and is a strong push into a 7- or 9-trait board.

Riot’s reasoning
Dark Ritual returns with less AP at every cashout.

Note: Re-enabled
AP Per Cashout: Cashout 2: 15changed to 12
AP Per Cashout: Cashout 3: 50changed to 33
AP Per Cashout: Cashout 4: 75changed to 50
AP Per Cashout: Cashout 5: 125changed to 100
AP Per Cashout: Cashout 6: 200changed to 175

MID.GG analysis

This Gold augment comes back nerfed. It is still usable for AP boards, but its late cashouts are much smaller.

Armor and Magic Resist: 4changed to 3

MID.GG analysis

The nerf trims its armor and magic resist bonus, so wide trait boards get slightly less defense from it.

Final Gold Gain: 5changed to 1

MID.GG analysis

The final gold reward is nerfed heavily, which makes this Prismatic a pure item play.

XP Gained per Round: 10changed to 9

MID.GG analysis

Less XP each round slows fast 8 lines slightly. The nerf is small but adds up over a game.

Riot’s reasoning
Trait Ladder underperforms in Gold and below but dominates Grandmaster+ lobbies with a 4.24 average placement, so its cashouts shrink.

4 Trait Cashout: Gold Granted: 6changed to 5
6 Trait Cashout: Gold Granted: 10 goldchanged to 7 gold
6 Trait Cashout: 3x3 costschanged to 2x3 costs
7 Trait Cashout: Component Anvil + 8 goldchanged to Component Anvil + 2 gold
8 Trait Cashout: 2 Different Components + Reforgerchanged to 2 Different Components
9 Trait Cashout: 3x5 costs + 2 goldchanged to 2x5 costs + 2 gold

MID.GG analysis

This Prismatic nerf mostly targets high-elo players who mastered it. Lower-ranked players were already losing with it, averaging a 5.22 placement.

Riot’s reasoning
Construct-A-Companion returns with a bug fix that guarantees you get the companion you built.

Note: Re-enabled

MID.GG analysis

This adjusted augment is back in the pool. Take it when you want a predictable unit for your planned comp.

Note: Re-enabled

MID.GG analysis

This adjusted augment is re-enabled, which gives flexible players another way to build a unit around their items.

Riot’s reasoning
Chosen of the Sun has struggled all set, so it moves from Gold to Silver to be played as a Leona-focused pick.

Tier: Goldchanged to Silver

MID.GG analysis

This adjusted augment is a strong Silver option for boards built around Leona.

Note: Disabled on 2-1

MID.GG analysis

This adjusted augment no longer appears on 2-1, so you have to pick it later, once you know your frontline.

Note: Disabled on 2-1

MID.GG analysis

Like the Silver version, this adjusted augment is removed from 2-1 offers.

Note: Now grants 4 gold

MID.GG analysis

This adjusted augment now adds gold, which gives it some econ value on top of its main effect.

Riot’s reasoning
Omega Riftbeast gets a new effect that powers up Alpha Riftbeasts further.

Note: Now grants Alpha Riftbeasts 15% bonus HP and 12% bonus Attack Speed

MID.GG analysis

This adjusted Gold augment adds health and attack speed to Alpha Riftbeasts. It supports the Mama Beak and Riftbeast lines.

Note: Now grants 4 gold

MID.GG analysis

This adjusted augment now grants gold, which makes the random items easier to build around.

Wisps

Good to knowWisp rule

All stat consumables (Knickknacks, Thingamajigs, and Doodads), Golden Goose, Major Gambit and Barter are no longer offered when the player is below 20 HP.

Attack Speed Bonus: 85%changed to 100%
Blossom Upgrade Attack Speed Bonus: 115%changed to 130%

MID.GG analysis

A bigger attack speed bonus favors single backline carries such as Ezreal or Xayah.

HP Increase: 750changed to 800
Blossom Upgrade HP Increase: 750changed to 800

MID.GG analysis

More health is a small buff for frontline-heavy boards.

Cost: 2 goldchanged to 1 gold
Blossom Upgrade Cost: 2 goldchanged to 1 gold

MID.GG analysis

A cheaper cost makes this buff an easy add on tight-gold rolls.

Attack Speed on Kill: 115%changed to 130%
Blossom Upgrade Attack Speed on Kill: 140%changed to 160%

MID.GG analysis

More attack speed on kill rewards carries that chain takedowns, like Rengar.

Duration: 6schanged to 8s
Blossom Upgrade Duration: 10schanged to 12s

MID.GG analysis

A longer duration protects carries that need time to ramp, so this buff favors scaling backlines.

Cost: 5 goldchanged to 6 gold
Blossom Upgrade Cost: 4 goldchanged to 5 gold

MID.GG analysis

The nerf raises its cost, so you need a little more gold to take it.

Mana Restored: 80changed to 70
Starting Mana: 20changed to 10
Radiant Mana Restored: 90changed to 80
Radiant Starting Mana: 20changed to 10

MID.GG analysis

The nerf cuts both the restore and the starting mana, so casters get less value from it.

What it does

Gives your whole team a mana top-up once combat passes the 8-second mark, with a bigger refill when Blossom upgrades it.

Riot’s reasoning
Low-cost Wisp variety is thin, so new 0-cost options appear under 10 gold to make low-gold rolls more varied and stop players forcing Salvager.

MID.GG analysis

Pick it on caster boards that need a second cast in long fights.

What it does

Adds armor and magic resist to your highest-health champion, with larger bonuses on the Blossom upgrade.

Riot’s reasoning
Low-cost Wisp variety is thin, so new 0-cost options appear under 10 gold to make low-gold rolls more varied.

MID.GG analysis

It helps any board with a single main tank. That is a useful patch now that Juggernaut is nerfed.

What it does

Grants a temporary Training Dummy holding Giant’s Belts, with an extra belt on the Blossom upgrade.

Riot’s reasoning
Low-cost Wisp variety is thin, so new 0-cost options appear under 10 gold to make low-gold rolls more varied.

MID.GG analysis

It suits fragile backline boards that need a body to absorb an engage.

What it does

Hands you a few random mushrooms, with one extra on the Blossom upgrade.

Riot’s reasoning
Low-cost Wisp variety is thin, so new 0-cost options appear under 10 gold to make low-gold rolls more varied.

Blossom Upgrade: Gain 3 random mushrooms.

MID.GG analysis

It is a flexible low-gold pickup. It rewards players who are already broke from rolling in Stage 4 and 5.

A few rule changes shape every game. Combat arrival and departure are each 1 second shorter. Below 20 HP, the shop stops offering stat consumables, Golden Goose, Major Gambit and Barter, so a last-life roll can no longer leave you broke with no combat Wisps. Four new 0-cost Wisps (Drizzle, Grove Armor, Returning Friend and Room for a Shroom) appear only when you hold under 10 gold, from Stage 4-1 to 5-7. Polymorph Wisps now show only in the first 2 seconds of Planning Phase.

Construct-A-Companion, Forge-A-Friend and Dark Ritual are back in the pool, and Dark Ritual returns nerfed. Heart of Steel is buffed on paper, but the mid-patch update disables it for now. The same update also fixes trait augments that were showing up too often and corrects two Wisp costs.

What to play

Contest the buffed reroll units early and pivot away from Emblem stacks. These are the picks we would test first.

Xayah (1-cost Solar reroll carry): five Solar units are buffed together, so the line that nearly disappeared last patch is live again. Her 43.9% pre-patch top-4 rate means you should watch early results before forcing her.
Lux (5-cost Lunar or Solar carry): Lunar now gives more AP from (3) upward, and her Solar bonus is adjusted to make that version her highest-damage variant. She already held a 68.1% top-4 rate.
Nidalee (4-cost AP carry for fast 8): her AP form’s spear damage rises and her AD form loses damage. Build her as the AP carry when you level aggressively.
Mama Beak (3-cost Riftbeast reroll): she is buffed in both the main patch and the mid-patch update, and Riftbeast (7) is buffed behind her. It is an untested line, so treat it as an experiment.
Ezreal (4-cost AD carry): he is buffed while Executioner is nerfed, so he no longer needs two or three Executioner Emblem carriers to win fights.

Watch outComps to fade

Veigar reroll is still viable, but it now needs a strong start or the right Artifact. The Coven 130 cashout pays out less. Kennen and Ashe are nerfed, yet they held 64.6% and 63.1% top-4 rates before the patch, so they remain strong when you hit them. For fundamentals on when to roll and when to level, see our guides.

Frequently asked questions

What changed in TFT Patch 18.4?

TFT Patch 18.4 moves power from Emblem-reliant vertical traits and easy frontlines into low-cost reroll units. Executioner, Juggernaut, Fae, Veigar, Kennen and Ashe are nerfed, while Solar reroll units, Lunar, Blossom, Sprykin and Riftbeast are buffed. Augments, items and Wisps also change, and four new 0-cost Wisps arrive for low-gold rolls.

Is Solar reroll good in TFT Patch 18.4?

Solar reroll should be playable again in Patch 18.4. Xayah, Rakan, Varus, Kayle and Shen all received buffs aimed at reviving the line, which was almost absent last patch. Their pre-patch top-4 rates were low, with Xayah at 43.9%, so treat it as a promising comp to contest rather than a guaranteed top-tier one.

Was Executioner nerfed in TFT Patch 18.4?

Yes. Executioner was nerfed in Patch 18.4, and its bleed damage at 3 and 4 units drops from 30/40% to 25/35%. Executioner (4) held a 73.2% top-4 rate before the patch, so it should stay competitive. Ezreal was buffed so his results depend less on Executioner Emblem carries.

What is in the TFT 18.4 mid-patch update?

The 7 October 2026 mid-patch update buffs Camille, Varus, Alistar, Gromp, Murkwolf, Warwick and Mama Beak, adjusts several Wisps and augments, and temporarily disables Heart of Steel. It also fixes trait augments that appeared too often, corrects two Wisp costs and disables a few Arenas that hurt performance. PC gets it before mobile.
