I love the game but just don’t know how to beat moloch(core) his ability to spawn tentacles and the poisoned hunger is just really hard to beat and yes I’ve tried radiance it helped but I still can’t win

Light spells on the core to gain advantage followed by an AoE attack like slash or splash worked for me. Lightning sword if melee, water skin if mage, and whatever autocast will let you frontload the most area damage at the start. The aim is to kill his adds before they can do anything while keeping a steady damage output going.
