TFT Set 18 — Blossom / Adaptor (Master Yi) Comp Guide

Set 18: Enchanted Wilds · Patch 18.2b · Updated Sept 16, 2026

The strongest statistical comp in the set right now: ~79% top-4 rate, 3.01 average placement. It's a Master Yi reroll board that abuses the Blossom trait to snowball Wisps into free stats.

Why this comp is strong

Blossom gives your champions bonus AD, AP, and max Health — and it empowers your Wisps after every combat. Since Wisps are the set's core economy/power mechanic, Blossom turns your shop into a compounding engine. Patch 18.2 also lowered Wisp costs across the board, so you keep gold for XP and rolling.

Master Yi is a 3-cost Adaptor. His passive makes every third attack a Double Strike (hits twice), and on takedown he gains a burst of move speed. His Adaptor bonus lets you choose:

• Double Strikes grant stacking attack speed → scaling DPS, better vs. long fights
• Double Strikes deal bonus damage and heal → drain-tank Yi, better vs. burst

Core board (Level 7–8)

Unit | Cost | Role | Target star

Master Yi | 3 | Primary carry | ★★★

Kog'Maw | 3 | Secondary carry | ★★★

Yorick | 3 | Frontline / Adaptor | ★★★

Krug | 3 | Frontline | ★★★

Vi | 3 | Main tank | ★★★

Sett | 3 | Bruiser | ★★

Nidalee (AP) | 4 | Flex carry | ★★

Gromp | 4 | Level 8 add | ★★

Flex slots: Sentinel (4-cost), Karma (early game filler).

If you highroll 4-costs, you can push 5 Blossom for maximum Wisp greed.

Items

Master Yi — primary carry

• Guinsoo's Rageblade (core — stacks with Double Strike)
• Edge of Night
• Titan's Resolve

Yi wants attack speed above all else. Despite his Adaptor heal bonus, one healing/sustain item is very reasonable if you want him as a drain tank.

Kog'Maw — secondary carry

Spear of Shojin · Rabadon's Deathcap · Jeweled Gauntlet

Nidalee (AP flex)

Guinsoo's Rageblade · Spear of Shojin · Rabadon's Deathcap

Vi — tank

Warmog's Armor · Gargoyle Stoneplate ×2

Augments

Economy (highest priority):

• Latent Forge
• Portable Forge
• Living Forge

Item augments:

• Forged in Strength
• URF
• Nesting Anvils

Combat options:

• Heroic Grab Bag
• Legion of Threes

Positioning

BACK    [ Master Yi ] [ Nidalee ] [ Kog'Maw ]

MID              [ Yorick ]

FRONT   [ Sett ]   [ Krug ]   [ Vi ]

Keep Yi in the back corner so he walks into the fight after your frontline has engaged and soaked the first burst.

Roll plan

Stage 2 — open strong

Play around a Master Yi opener that can win streak. Blossom is very powerful early. Prioritize win-streaking for gold and item drops.

Stage 3 — build the shell

Add your Adaptor units and frontline. Finish Master Yi's items by the end of this stage — he should be fully itemized before you commit to rolling.

Stage 4 — the roll-down

Level to 7 and roll for:

• Master Yi ★★
• Kog'Maw ★★
• A Juggernaut tank

Then slow roll at 7 to hit your 3-stars. Don't dump your whole bank at once — slow roll down to ~30–50 gold and let interest rebuild.

Stage 5+ — cap the board

Level to 8 and add Gromp. From Stage 5 onward, every other Wisp is a Combat Wisp, and Blossom has been empowering them all game — this is where the comp spikes hardest.

Wisp notes (important for this comp)

• Wisps appear in the rightmost shop slot every other round, purchasable during planning only.
• One Wisp per round max. If you skip it, the hidden unit behind it is revealed after planning.
• Categories: Champion, Combat, Misc, Shop, Gold/XP, Risky, Item — color-coded in shop.
• Costs range 0 to 45+ gold, and every purchase competes with your interest breakpoints. Think before you buy.
• Because Blossom empowers Wisps after each combat, your Wisps are better than everyone else's. Lean into buying them more aggressively than you normally would.

Quick decision rules

✅ Force this comp if: you hit early Master Yi copies, get an attack-speed item opener (Recurve Bow / Rageblade components), or find a Blossom emblem.

⚠️ Pivot away if: you're contested by 2+ players on Yi, or you're deep into Stage 4 without Yi ★★ and low on HP.

🔄 Alternative Blossom line (Fast 8): If you fall into AP items instead, play the Ahri / Sett / Ashe Blossom board — Ahri wants Eternal Pact + Spear of Shojin + Jeweled Gauntlet, Ashe wants Red Buff + Spear of Shojin + Last Whisper. Standard fast-8 econ: 4→5→6→7→8, never drop below 10 gold at 8.

Meta context

TFT Academy lists no S-tier comps on Patch 18.2b — it's an open meta. Other strong lines to keep in your pocket: Fae/Spyrkin Rengar, Aphelios + Nidalee (rising fast), Ahri Sett Blossom, Caitlyn Reroll, Solar Reroll, Riftbeasts.

Play flexible. Follow your items and augments rather than hard-forcing from Stage 1.
