I crashed the game, I don't know how to proceed anymore!
(spoiler alert)
what potion is needed to heal the shopkeeper?
and what illuminates the corrupted depths of the temple?
Aight you need spectral sirup to cure the shopkeeper and you need goowshrooms from in the northcrest cave entrance to craft an amulet for light. (You don't craft it you speak with Othra/the witch for it.) Oh also the cave is only unlocked after the bandit camp event is finished, so you can't access the corrupted depths yet.
