Genshin Reaction Teams Guide: Vaporize, Melt, Hyperbloom, Freeze & Lunar Comps for 6.7

A reaction team is built around reliably triggering one specific elemental reaction every rotation, instead of stacking 4 strong-but-unrelated characters together. Three big groups:

• Amplifying: Vaporize, Melt — multiplies the base hit damage by a fixed coefficient, independent of the trigger character's Elemental Mastery.
• Transformative: Hyperbloom, Burgeon, Overload, Superconduct, Swirl, Crystallize, Burning... — deals its own separate damage instance that scales heavily with the triggering character's Elemental Mastery.
• Additive: Aggravate, Spread — technically a different reaction family from Transformative, but the same mechanic: its own separate damage scaled by the trigger character's Level + Elemental Mastery.

The most common mistake is forcing a copy-pasted comp from the internet when your own roster doesn't have the right carry for it. The correct order is to audit which Dendro/Electro/Hydro/Pyro/Cryo characters you actually own first, then pick an archetype below. See the full coefficient table and classification on our Elemental Reactions page; the standard 4-role framework is on How to Build a Team.

Vaporize is an Amplifying reaction where the multiplier depends on the ORDER elements touch the target, not a single fixed direction — cross-verified across ≥2 sources (hoyolab + gamemarket team-building guides):

• Pyro hitting a target already carrying Hydro = x1.5.
• Hydro hitting a target already carrying Pyro = x2 — the noticeably higher coefficient.

That splits into 2 build directions: forward Vaporize uses a Pyro carry (e.g. Hu Tao, Yoimiya) paired with a Hydro applier (Xingqiu, Yelan) — only x1.5, but the Pyro carry brings its own huge burst mechanics; reverse Vaporize uses a Hydro carry (e.g. Neuvillette) paired with a Pyro applier (Bennett, Xiangling) — a full x2 on every on-field hit. Either direction still needs a Support/Sustain slot to keep the rotation running — 2 characters alone don't make a full team of 4.

Melt is also Amplifying, but its coefficient direction runs OPPOSITE to Vaporize's (cross-checked across ≥2 independent community sources):

• Pyro hitting a target already carrying Cryo = x2 (forward Melt, Pyro carry).
• Cryo hitting a target already carrying Pyro = x1.5 (reverse Melt, Cryo carry).

Forward Melt: Diluc/Klee as the Pyro carry, paired with a Cryo applier (Chongyun, Diona) — the single highest coefficient among all Amplifying reactions. Reverse Melt: Ganyu/Ayaka as the Cryo carry, paired with a Pyro applier (Bennett) — only x1.5, but still hugely popular (the classic "Melt Ganyu" pairing with Bennett) because the Cryo carry's own crit mechanics push real damage well above what the lower coefficient suggests. Which direction to pick depends on the carry you already own, not on chasing the bigger raw number.

Freeze (Cryo+Hydro) doesn't multiply damage like Vaporize/Melt — it hard-locks the target instead. A frozen enemy can't retaliate, can't move, and is almost immune to hitting you back. The classic comp: a Cryo carry (Ganyu, Ayaka) + a Hydro applier that keeps refreshing the freeze window (Kokomi, Mika) + a secondary cold source + 1 support.

Per our master data cross-checked against multiple community sources, even though 6.7 leans heavily toward the Lunar reactions (Lunar-Bloom, Lunar-Charged, Lunar-Crystallize) and Mavuika's Melt, a Freeze team built around Skirk still sits above every other archetype — the specific reason: Furina, the single most universal reaction support in the game right now, doesn't fit into Lunar comps, so she's effectively "kept back" anchoring Freeze instead of migrating to Lunar. It's the clearest proof that picking a reaction should follow the carries you actually have, not whatever's trending.

Bloom (Dendro+Hydro) is the base reaction: it spawns a Dendro Core that explodes on being hit. Which element hits the core decides the branch:

• Hyperbloom (hit with Electro): damage scales with the trigger character's level and Elemental Mastery — no attack-range component involved, so stack EM hard on your trigger. Standard team: Nahida (applies Dendro) + a Hydro applier (Yelan, Xingqiu, Kokomi) + a high-EM Electro trigger (Fischl, Kuki Shinobu) + 1 support.
• Burgeon (hit with Pyro): AoE explosion scaled by the trigger character's level and Elemental Mastery (not ATK%), using Xiangling/Yoimiya, great when you need to clear crowds.

Separately, Quicken (Dendro+Electro) lays down an Electro-Charged-like aura that unlocks 2 Elemental Mastery-scaled branch reactions: Aggravate (Electro hitting the aura — Electro carries like Raiden Shogun, Yae Miko) and Spread (Dendro hitting the aura — Dendro carries like Tighnari). Which one you pick depends on whether your main carry is Electro or Dendro.

These 4 long-standing Transformative reactions rarely serve as your main damage axis, but each is still genuinely useful in specific situations:

• Overload (Pyro+Electro): an AoE burst that knocks enemies back — great for breaking up clumped groups, but rarely a carry mechanic since the knockback can push enemies out of attack range.
• Superconduct (Cryo+Electro): heavily shreds Physical RES in an area around the burst — pairs perfectly with normal-attack/Physical-scaling carries (Eula, Razor).
• Swirl (Anemo touching another element): spreads that element in an AoE and shreds the corresponding elemental RES on anything hit — this is what makes Kazuha, Sucrose, and Venti slot into ALMOST ANY team, regardless of what reaction you're actually building around.
• Crystallize (Geo+another element): drops a pickable elemental shield shard, deals no damage, but Geo comps like Zhongli, Albedo, Itto use it to generate their own free shields instead of borrowing one from another character.

Burning (Dendro+Pyro) creates a fire zone dealing damage over time, rarely a main carry mechanic since each tick is relatively weak, but genuinely useful for continuously clearing crowds or exploring wide areas without needing precise aim.

Version 6.7 introduces an entirely new reaction group called Lunar, which only triggers when a Lunar-aligned character is in the party, and it took off hard once Columbina launched (version 6.5) — Columbina is both a strong sub-DPS and a universal Lunar reaction support, slotting into all 3 comps below:

• Lunar-Bloom: representative team uses Nefer/Lauma.
• Lunar-Charged: representative team uses Flins/Ineffa.
• Lunar-Crystallize: representative team uses Zibai/Linnea.

Just Columbina + one matching Lunar character already gives you a solid core; the remaining 2 slots are flexible based on your roster. This path is worth investing in if you already own Lunar characters, but it's NOT mandatory to swap a team that already works well into Lunar just because it's new.

A 3-step process — not just copying whatever team looks strong online:

1. List which Dendro/Electro/Hydro/Pyro/Cryo/Anemo/Geo characters you own that are actually carry-viable.
2. Cross-reference against the archetypes above and see which one you have 2 real core pieces for (1 trigger/carry + 1 element-applier).
3. Fill the remaining 1-2 roles (support/heal/buff) with your Flex slot — see the full role framework on How to Build a Team.

Don't have strong Lunar/Dendro characters yet? The National team (Xiangling/Bennett/Xingqiu + Chongyun or Sucrose) still triggers Vaporize/Melt reliably every rotation, costs the least to build F2P, and remains a safety net that never goes out of style.

Checklist before finalizing: (1) do you have a clear main carry; (2) do you have exactly the right applier elements to trigger your target reaction, not missing or overlapping into an unwanted one; (3) is the Elemental Mastery of your Transformative-reaction trigger meaningfully built (full formula on our Elemental Reactions page); (4) is Energy Recharge steady enough to burst every rotation; (5) have you picked the right Elemental Resonance for this comp (full table on Elemental Resonance).
