Debuffer
3: Fires earliest among back-row slots; applies burns and Ash before other damage dealers act, maximizing DOT uptime.
4: Standard DPS slot; works well when another AOE hero needs pos 3 priority.
5: Viable but delays Ash application; use only if pos 3 and 4 are occupied by higher-priority carries.
Kobayakawa is a burn-focused AOE mage whose Flaming Feast deals devastating front-row damage (3x base, 4x with Puppet Bunny exclusive gear) while applying sustained damage debuffs via Death Descend. Her Kitten’s Daydream ultimate weapon creates Ash effects whenever Minutemen teammates apply status effects, then detonates that Ash for massive burst through her Focus skill. She anchors Minutemen DOT compositions by bridging burn, poison, and bleed chains into a unified Ash detonation loop.
Pros & Cons
- Flaming Feast deals 3x (4x with Puppet Bunny) damage to front-row tanks, punishing standard tank-heavy formations.
- Kitten’s Daydream UW creates Ash on Minutemen status procs (40% chance), adding a unique detonation layer to DOT comps.
- Death Descend makes targets take +100% sustained DMG for 2 rounds, doubling all teammate DOT and direct damage.
- Ill-Tempered stacks +5% DMG per hit (3 stacks), rewarding sustained focus on a single target.
- Puppet Bunny exclusive gear adds +22.5% DMG vs burning targets, synergizing perfectly with burn-heavy lineups.
- Heavy Armor reduces Initiative by 10%, making her slower to act despite LUK investment.
- Fragile backrow INT hero (VIT 299) — vulnerable to backrow snipers like Kelly and Galande.
- Ash mechanic requires Minutemen teammates applying statuses; weaker in mixed-faction or status-light lineups.
- Front-row 3x/4x multiplier is wasted against lineups that run only one tank or use backrow-only strategies.
Skills
Deals 30/34/38/42/45% TAC DMG to all enemies and 3x more DMG to the front-row targets or targets without any allies in the front.
Deals 2.5/3/3.5/4/5% more DMG to the target, stackable for up to 3 times, lasting 3 rounds.
The Hero’s Initiative -10%, while taking 10/11/12/13/15% less DMG (% DMG Reduction).
Casting "Flaming Feast" will deal an additional 15/18/21/24/30% TAC DMG.
When casting "Flaming Feast", makes the target become grievously wounded and take 50/60/70/80/100% more sustained DMG for 2 rounds.
Gear
Puppet Bunny is best-in-slot and should be prioritized whenever available — the 4x front-row multiplier and +22.5% burn DMG are both massive in her core compositions. Resolute is the universal fallback for survivability. Hurricane is a solid early option before exclusive gear is unlocked. Apocalypse and Ripper offer niche value in crit-focused or self-sustaining builds.
Exclusive set. 2pc gives +22.5% DMG vs burning targets (always active in burn comps). 4pc upgrades Flaming Feast from 3x to 4x front-row DMG — a direct 33% increase to her signature skill’s front-row multiplier.
#1 Best
Standard DPS survivability. +0.4% ATK per 1% HP lost synergizes with her tendency to take hits in extended fights. Death immunity with 30% HP restore and +50% DMG on next attack is a crucial safety net for a VIT 299 hero.
#2
+15% Crit Rate and +30% Crit Damage. Strong when Flaming Feast hits multiple targets — each hit rolls for crit independently, so more targets means more value from crit stats.
#3
Normal attacks cause bleeding, which triggers Kitten’s Daydream Ash application (40% chance). Creates a self-sustaining Ash loop without relying solely on teammates.
#4
+10% ATK and +35% DMG after killing a target. Snowball set that rewards Flaming Feast finishing off weakened front-row tanks.
#5
+8% TAC DMG Bonus and +24% Focus DMG. Straightforward damage boost that benefits both normal attacks and Flaming Feast. Good early-to-mid game option before exclusive gear is available.
#6
Kobayakawa is an INT damage dealer with the lowest survivability tier (VIT 299). Prioritize INT and DMG Bonus on offensive slots (weapon, jewelry) and HP/DEF/VIT on defensive slots (helmet, body). She does not benefit from STR or WPN ATK substats at all.
DMG Bonus, INT, Crit Rate
DMG Bonus is the universal damage multiplier; INT scales TAC ATK for all her skills; Crit Rate adds burst potential to multi-hit Flaming Feast.
HP%, AGI, VIT
Survivability stats to compensate for her extremely low VIT (299). HP% is the most efficient defensive stat; AGI helps against AGI-targeting skills.
DEF, VIT, DMG Mitigation
Pure defense. Keeps Kobayakawa alive through the early rounds until Flaming Feast and Ash detonation can take effect.
DMG Bonus, INT, Skill Effect Enhancement
DMG Bonus and INT maximize Flaming Feast and Ash detonation damage; Skill Effect Enhancement directly boosts multipliers on all skill-based damage.

Synergies
Benson’s Hellfire burns all enemies every skill cast, with Hellfire UW allowing 15 burn stacks. Each burn application by a Minuteman triggers Kitten’s Daydream (40% chance to apply Ash). Benson also grants +8% DMG to all Minutemen via Nirvana. Puppet Bunny’s +22.5% DMG vs burning is always active when Benson is on the team.
Ivanov’s Hammer of Judgement detonates Poisoned/Burning/Bleeding statuses. Kobayakawa’s Flaming Feast and Armor-Piercing Ammo apply burns that Ivanov detonates for massive burst. Winter Drink makes Kobayakawa’s burns deal +30% more damage. Death Descend’s +100% sustained DMG debuff doubles Ivanov’s detonation hits.
Margaret’s News Coverage has a 50% chance to reapply expiring Poison/Burn/Bleed, keeping Kobayakawa’s burns alive indefinitely. Each reapplication triggers another 40% Ash chance from Kitten’s Daydream. Joint Signature boosts all Minutemen Poison/Burn/Bleed DMG by +10% (+2% per Minuteman deployed).
Heytex’s Blaze Shark UW fires extra bullets whenever Minutemen teammates apply status effects. Kobayakawa’s burns and Ash effects trigger these bullets repeatedly. Death Descend’s +100% sustained DMG debuff on targets amplifies all of Heytex’s rocket hits on those targets.
Bolton’s AC Shield UW (200% max HP shield at battle start) provides the durable front line Kobayakawa needs to survive long enough for DOT stacks to accumulate. As a Minuteman, Bolton contributes to faction bonuses and triggers Kitten’s Daydream Ash when his skills apply statuses.
Interactions with other heroes’ ultimate weapons.
Hellfire UW lets burning stack up to 15 layers and applies Burning after heroes deal damage (up to 5 procs/round). Each Burning application by a Minuteman has a 40% chance to trigger Kitten’s Daydream Ash. With 15 burn stacks generating constant reapplications, Ash accumulates rapidly for Kobayakawa’s Focus skill detonation (+80% ATK DMG per Ash consumed).
Thunder Hammer gains 100 Focus per Poison detonated, +3% ATK (stacks 12) per Burning detonated, and heals lowest-HP teammate per Bleeding detonated. Kobayakawa’s burns feed Ivanov’s detonation chain — each Flaming Feast applies burns to all enemies, giving Ivanov multiple statuses to detonate with Hammer of Judgement for both damage and ATK scaling.
Blaze Shark fires extra bullets whenever Minutemen allies inflict status effects (up to 5 bullets/round). Kobayakawa’s Kitten’s Daydream Ash procs count as status applications, triggering additional Blaze Shark bullets. The burn from Flaming Feast and Ash from normal attacks create a dual-trigger loop that maximizes Blaze Shark output.

Counters
- Casino (Hard Counter) — Casino’s Double Down drains 200 Focus from all enemies, preventing Kobayakawa from casting Flaming Feast. Without her Focus skill, she cannot apply mass burns, trigger Death Descend, or accumulate Ash for detonation — her entire kit relies on skill activation.
- Kelly (Soft Counter) — Kelly’s Hunting targets the lowest-AGI enemy. Kobayakawa’s Heavy Armor reduces Initiative by 10%, making her even more vulnerable to AGI-based targeting. Spine Whip UW gives Kelly a chance for double actions, potentially killing Kobayakawa before Flaming Feast fires.
- Blanche (Soft Counter) — Blanche’s Eradicate deals 260% + 100% WPN DMG to a random backrow enemy. Kobayakawa in pos 3-5 is always in Blanche’s targeting range. Her low VIT (299) means a single crit from Eradicate can eliminate her before DOT chains establish.
- Front-row tank lineups (Hard Counter) — Flaming Feast deals 3x (4x with Puppet Bunny) damage to front-row heroes. Lineups that invest heavily in dual-tank formations (pos 1-2) take devastating punishment — their tanks melt while backrow carries lose their protection.
- Low DMG Mitigation lineups (Soft Counter) — Death Descend makes targets take +100% sustained DMG for 2 rounds. Lineups without strong DMG mitigation or cleanse have no way to remove this debuff, effectively doubling all incoming damage from the entire Minutemen team.
Rating
A Tier. Strong AOE damage dealer with excellent DOT synergy within Minutemen compositions. Kobayakawa shines in burn chain lineups where her Ash mechanic creates multiplicative damage with Benson, Ivanov, and Margaret. She lacks the standalone carry power of S-tier heroes like Heytex but serves as a critical enabler in status-heavy teams. Her 4x front-row damage with Puppet Bunny makes her one of the best front-row punishers in the game.
