Mutant Parasite
BossMutant Parasite is the 2nd story boss inside School Grounds, a haunted school campus infested with living curses. It caps a 15-wave act that opens with 8x School Curse, 8x Fabric Curse in wave 1 and scales up to a final wave of 11x School Curse, 14x Fabric Curse, 1x Insect Curse (Elite), and Mutant Parasite itself. Its health pool and aggression sit noticeably above the Basic and Elite spawns that lead up to it.
Enemies in this act can carry the Sprinter, Tank modifiers: Sprinter (trades health for a large burst of movement speed); Tank (trades speed for a larger health pool).
Compared to Act 3's closing boss Centipede Curse, Mutant Parasite is an earlier, more approachable check in School Grounds' Story campaign, though it still requires a full 15-wave clear rather than a solo encounter. Mutant Parasite also appears as the 2nd fight in School Grounds Expedition's elite gauntlet, a separate encounter from its Story act.
Details
Where Mutant Parasite Appears
Mutant Parasite closes out School Grounds Act 2 in Story mode, appearing only in that act's final wave alongside the zone's Basic-tier fodder and a companion Elite spawn. It does not appear in any other School Grounds Story act. It also reappears as the 2nd fight in School Grounds Expedition's elite gauntlet, a separate encounter from its Story act.
Story Wave Composition
School Grounds Act 2 runs 15 waves total. Wave 1 opens with 8x School Curse, 8x Fabric Curse, the midpoint wave 8 throws 10x Fabric Curse, 9x School Curse at the field, and the final wave caps the act with 11x School Curse, 14x Fabric Curse, 1x Insect Curse (Elite), and Mutant Parasite anchoring the push.
How to Counter Mutant Parasite
Since Mutant Parasite's wave carries the Sprinter, Tank modifiers (Sprinter (trades health for a large burst of movement speed); Tank (trades speed for a larger health pool)), building a team that can handle those effects matters as much as raw damage against Mutant Parasite itself.
