Hello, I'm Apophis-Set and I'll be writing how to solo each boss:
(Keep in mind this is mainly for soloing, I'll be writing a thread on how to do with a group later :3)
(Also keep in mind that for snarbolax, I'm assuming you have 2 star equipment, 2 weapon slots and no trinket slots. For jelly king and roarmulus twins, I'm assuming you have 3-4 star equipment, 3 weapon slots and no trinket slots. For vanaduke, I'm assuming you have 5star equipment, 4 weapon slots and 2 trinket slots. If you have a different star set, just assume the weapon in the same line)
