The Fight▾
Resistance is the signature stat (Ironbrand can only be RESISTED, never blocked/removed; its duration scales with the target's ATK/DEF). Single-hit only (multi-hit -50% per subsequent hit), poison -90%, MAX-HP damage capped 10%. Boss gains 10% TM per buff an ally receives — run buff-light. 50% Dec ACC halves boss ACC: resist target drops ~505→305 (st.13-15), ~355→230 (7-12), ~205→155 (1-6).
Team
Gwyndolin the SilentFA2 50% Dec ACC halves the resist wall + 30% Dec SPD; A1 extends all debuffs (uptime). 6★, ACC-scaling passive—
GeomancerFHP Burn dodges the poison nerf; single-hit AoE A1; A3 adds Weaken + TM steal—
Aox the RemembererFAoE 50% Dec ATK + TM cut; extension passive keeps Dec ACC/DEF rolling; team heal—
VogothSPassive team heal + Leech; HP-scaler eats short Ironbrands (duration keys off ATK/DEF)—Affinity
Rotates on the potion-keep weekly schedule (Magic/Spirit/Force/Void). Off-affinity champs amplify the boss's growth effect — match the day, don't stack counter-affinity.
Levers
- ›Stack RES to the bracket threshold (155/230/305 with Dec ACC up) — Dec ACC can whiff, RES is the floor.
- ›Buffs feed the boss 10% TM each — skip team buffers (Kurzad/Skeletor Inc ACC, Sachi); gear ACC on debuffers instead.
- ›HP Burn is the damage engine of choice: not poison, not max-HP-scaled, single application.
- ›Favor HP-scaling bodies — Ironbrand duration scales with the victim's ATK/DEF.
- ›Stag Knight to 6★ (priority queue #3) is the single biggest upgrade for this team.
Swaps
- Bowf the RancidS
Dedicated AoE 50% Dec ACC (75%) on a tanky healer if Gwyndolin is needed elsewhere — HH rates him IT 4. 4★
- SkeletorS
Dec SPD + debuff extension + Dec RES passive helps land the ACC debuff — but his Inc ACC buff feeds boss TM
- Kurzad DeepheartV
Backup 60% Dec DEF; team Inc ACC = 5 buffs = +50% boss TM, a liability here. 3★
- Vallaryn the EqualizerM
Team-wide Weaken if Geomancer sits; execute (10% cap) and Heal Reduction do nothing vs this boss
- AnaxS
Budget Dec DEF/Dec ACC/Weaken in one body; outclassed by Stag, poison dead, 2-hit A1 penalized
Alternative Comps
Ideal (fully built)
dream teamIf every owned champ were 6★ + geared — the build-goal lineup.
Stag Dec DEF/ATK + Gwyndolin Dec ACC/SPD is the debuff spine; Aox extension passive keeps it all up; Geomancer burns, Vogoth sustains. Still to 6★: Stag Knight only. Dilgol/Kurzad build plans for this content cancelled.
