Character Summary
Klukai is an AOE damage dealer specialist that excels in general content where she can bulldoze through mobs with her potent Ultimate skill. Owing to the low stat scaling on general content, Klukai’s damage range conveniently exceeds the health on most stage mobs; this, combined with her extremely high AOE radius, lets her trivialize general content.
Klukai differs from existing AOE damage dealers in that her Ultimate skill has exceptionally large range, repositions her, and can be immediately used again if the initial cast kills at least two targets, effectively allowing Klukai to blitz her way across the map with double-cast ults running over anything in her way.
While character dupe performance is generally confined to its own section, it would be careless to discuss Klukai without mentioning her V6. Klukai is most notorious for her game-breaking V6, which builds on her existing niche, turning her from a specialized AOE damage dealer into one of the strongest single-target damage dealers in the game. While V6 is generally unattainable to the average player, Klukai(V6)’s prevalence in Gunsmoke as a premier (mandated) support makes her common enough to warrant covering.
Fixed Keys
Fixed Keys core to Klukai’s function are:
02-03 - One Fell Swoop: Compensates for Klukai’s low base skill multipliers with Klukai’s damage in single-target scenarios with a sizable +DMG% increase to the Ultimate skill.
04-03 - Strong Support: Confectance Index gain greatly improves Klukai’s passive Ultimate skill cooldown reduction effect to significantly improve uptime on the skill.
06-01 - Limit Break: Further +DMG% buffs to Klukai’s Ultimate skill at the trade-off of a reduced AOE radius. Most relevant in single-target scenarios, where her effectiveness as an AOE damage dealer isn’t as relevant.
Mod Key
Klukai doesn’t have a Mod Key available yet.
Character Function
Klukai’s main use case is as a stage-dependent AOE specialist in situations where it would be more effective to bring a dedicated AOE damage dealer than to deal with trash mobs using a typical team of single-target damage dealers. As mentioned above, this use case happens to cover all general content (Campaign, Event, Expansion Drills 1~10, all other trivial content).
At V6, Klukai(V6) retains her AOE niche while simultaneously becoming a single-target damage dealer powerhouse that combines:
Extremely high single-target damage ceiling (at V6)
DEF% reduction, up to 15% (at V2)
Defense Down II, 2 turns applied before attack (at V3)
Character Synergy
Klukai(V0) is brought along primarily to deal with specific stage mechanics (i.e. large groups of enemies or any AOE needs). Her kit functions independently of the rest of the team.
Klukai(V6) needs support to enable her rotation. To briefly detail the mechanics behind Klukai(V6)’s Ultimate double-cast:
Klukai’s Ultimate skill is on a 6 turn cooldown
Klukai passively reduces the cooldown of her Ultimate skill by 1 turn for every 3 points of Confectance Index gained.
Klukai(V2) further reduces the cooldown by an additional 1 turn for every 3 points of Confectance Index gained.
Klukai has 3 ways of gaining Confectance Index:
+1 Confectance Index for every instance of Corrosion damage dealt
+1 Confectance Index for every instance of allied Corrosion damage dealt
+1 Confectance Index for every instance of support attack dealt by allies (Fixed Key 04-03)
Klukai needs to gain 9 Confectance Index within a turn to fully refund the cooldown on her Ultimate skill (3:2 CI:CD * 3 = 9:6 CI:CD)
Klukai herself gains +2 Confectance Index off her Ultimate double-cast
Klukai needs +7 Confectance Index from external sources
Across Klukai’s common team comps, her +7 Confectance Index comes from:
Peritya (with/ without Mechty): Klukai(V6) is commonly paired with Peritya(V0) as an enabler for Peritya’s Action Support procs, allowing Peritya to fully capitalize on her passive by triggering all 6 instances of Action Support every turn. Beyond damage, this feeds back into Klukai(V6)’s Confectance Index gain:
+6 Confectance Index for 6 instances of Peritya’s Action Support (passive)
+1 Confectance Index for Peritya’s Corrosion active skill
Qiongjiu(V3)-Sharkry (without Vector): Klukai(V6) is frequently taken as a standalone 5th slot damage dealer in the absence of a stronger alternative. Klukai(V6) is able leverage:
+4 Confectance Index for 3 + 1 instances of Qiongjiu’s Action Support (passive)
+3 Confectance Index for 3 instances of Sharkry’s Wise Support (Fixed Key)
Qiongjiu-Vector: Klukai(V6) is frequently taken as a standalone 5th slot damage dealer in the absence of a stronger alternative. Klukai(V6) is able leverage
+7 Confectance Index from the team’s Action Support procs
Tololo(V2)-Springfield(V6): Within the premium Hydro duo, Klukai(V6) notably capitalizes on Springfield’s summon’s attacks to reset her own Ultimate skill cooldown:
+3 Confectance Index for 3 instances of Springfield(V6)’s summon’s Action Support (up to 4, on allied active Hydro damage dealt) triggered by Tololo(V2) as part of her triple-turn rounds
+2 Confectance Index for 2 instances of Springfield(V0)’s summon’s Counterattack
Vertebrae Breakpoints
SSR characters are reviewed at V0/V1 strength. However, for those especially dedicated players, it is worth noting Klukai’s significant dupe powerspikes at:
V3: V3 greatly eases Klukai’s Ultimate skill double-cast conditional trigger, which allows her to function in some limited capacity as a single-target damage dealer in addition to her usual AOE niche. Klukai’s single-target damage is worse relative to other dedicated single-target damage dealers (e.g., Qiongjiu); for this reason, V3 is typically considered less a breakpoint and more a stepping stone on the way to V6.
V6: As covered extensively above, V6 is the basis for Klukai’s dominant presence in Gunsmoke as a single-target damage monster. V6 is notable in that it allows Klukai to single-handedly enable Peritya (6 Action Supports/ turn), as well it adds additional “on-hit” damage instances (see Skill 2, Passive) to the Ultimate skill.
Pros & Cons
Pros
Trivializes all general content by sweeping away anything short of Elite mobs with her Ultimate skill.
Cons
Klukai(V0~V2) is woefully ill-suited for content that favors single-target damage dealers (e.g., Gunsmoke).

Scylla

Planeta
in damage at all Klukai dupe levels with and without Scylla’s conditional Corrosion weakness effect active. Owing to Klukai’s significant power spike at V6, players are heavily encouraged to prioritize Klukai’s dupes over her signature weapon. For this reason, Planeta is commonly viewed as the more cost-effective option.
