Just a warning to anyone that want to play this game, theres 3 char slots but none of them share any currencies, achievements, unlocks etc. Your 2nd chars starts at square one 

On that note, if you really want to play this game, I would recommend range class. Melee class have disadvantage fighting bosses.

Made an 2nd char archer because of that. 0 crystalls    but was worth it:
- can kill everything from range, why dodge when you never got hit in the 1st place
- only need to worry about upgrading weapon (glass cannon ) Its PITA to gather.
- no worry about getting swarmed from mobs
