no offense or anything Goose23 but i was Psych and beat the Hydra fairly easy with Wraith and Psychopath form, Dark Infusion, Corruption, Epiphany, and Terrify
for the Baron on bio i just used disrupt..then on my hydraulic i just hit him,let him use his mana,then stun when someone gets low hp and heal, then pretty much the same thing on my psychological except i couldnt stun so healing was harder (just felt like randomly putting this xD)
