Berserker
Berserker is the boss encounter at the end of Spirit City Act 3, the final and toughest of the three Raid acts set in Spirit City. Like every Boss-type enemy, it carries a hidden Boss tag on top of its listed stats that adds a flat 20% health multiplier and a 30% speed penalty, while capping incoming Stun and Rewind effects at 10 stacks rather than blocking them outright. Spirit City Act 3's wave also runs the Immunity modifier across its full spawn list, which does fully block crowd control on Berserker itself, so stun and slow effects will not land on it regardless of stack count.
As a Boss-tier enemy, Berserker moves at the tier's baseline speed multiplier of 1.68 and is modeled at 0.8x scale, both noticeably larger and slower than the Basic-tier Soul Reapers and Soul Footsoldiers that fill out the rest of the wave. The Greed modifier also present in Act 3 periodically drains health from placed units standing nearby, which is separate from Berserker's own stats but worth planning positioning around during the fight.
Clearing Spirit City Act 3 with Berserker as the final boss pays a flat 125 Gems, 125 Gold, 145 Player EXP, and 1000 Unit EXP, the same base reward as the other two Spirit City acts, plus 20 Raid Tokens and 20 Spirit City Tokens. Berserker's specific headline drop is the Kenpachi unit, at a 1% chance per clear backed by a 35-clear pity counter, making repeated Act 3 clears the most reliable way to add that unit to a roster outside of the standard gacha banners.
Details
Where Berserker Appears
Berserker only shows up as the final wave of Spirit City Act 3, the last and toughest of the three Spirit City Raid stages. Raid content is Hard-difficulty only, and Act 3 caps a shared 15-wave structure built from Soul Reaper and Soul Footsoldier spawns that Spirit City Act 1 and Act 2 also use, just with Berserker standing in for the earlier acts' bosses at the very end.
Because Berserker is locked to Raid, it never shows up in Story, Expedition, Infinite, or Mastery content, so farming it specifically means running Spirit City Act 3 on repeat.
Combat Behavior
As a Boss-type enemy, Berserker carries a hidden tag that adds a flat 20% health multiplier and a 30% speed penalty on top of its listed stats, and moves at the Boss tier's baseline speed multiplier of 1.68 while modeled at 0.8x scale, larger and slower than the Basic-tier enemies filling out the rest of the wave.
Spirit City Act 3's wave list runs the Immunity, Tank, Sprinter, and Greed modifiers. Immunity fully blocks crowd control on every enemy it touches, including Berserker itself, overriding the usual Boss-tag rule that would otherwise just cap Stun and Rewind stacks at 10. Tank and Sprinter spawn on the Basic-tier enemies around it, trading speed for health or health for speed, and Greed periodically drains health from units placed near whichever enemy carries it.
How to Counter Berserker
Since Immunity blocks stun, slow, and other crowd control outright on this wave, teams should lean on raw sustained damage rather than lockdown strategies to bring Berserker down.
Because Greed drains health from units standing close to the enemy carrying it, spreading placements out across the map rather than clustering high-value units together limits how much any single tick can siphon during the fight.
Rewards for Clearing Spirit City Act 3
Defeating Berserker at the end of Spirit City Act 3 pays a flat 125 Gems, 125 Gold, 145 Player EXP, and 1000 Unit EXP, the same base currency reward as Spirit City's other two acts, plus 20 Raid Tokens and 20 Spirit City Tokens on every clear.
Berserker's specific headline drop is the Kenpachi unit, at a 1% chance per clear backed by a 35-clear pity counter, making repeated Act 3 runs the most reliable way to add Kenpachi to a roster outside of the standard gacha banners.
