Depends on the difficulty level, in the lower levels you could have taken more supplies with you.
Worst of all, there is a huge dungeon in the game that I completely hated.
Ah, right. Never played below veteran, or whatever "hard" was called.
Yeah, Endless Dungeon of Caed Nua - one of many PoE kickstarter promises that shouldn't have been made. Cool concept and cool story. Cool visual design. Way, way too long and far too few unique encoutners.
