Those are ridiculous, HP pool of pitbosses are already high enough, but these have 200%.
Seahag, Hivemind and Lizard.
Especially seahag, with one shot gray on gray color pond, a massive body hitbox that makes all casts and shadows invisible.
Gray on gray pond also has a slow effect making it impossible to run away intime (also due to latency)
Overall I think it is the worst by far boss designed in the Pit. In the end stage she summons 3 shadows at once + her own projectiles. Dodging them all is possible but then you won’t kill the boss, unless you playing necro.
