How to Make Money
If you know for sure you can’t win, and have the ability to go back to the start and retire, it’s definitely better to do that then die.
Making money depends on what point in the game you are at. Early on you can do dungeons with no preparations so you’re not losing extra gold to those.
Anything you bring out of a dungeon like extra potions, money, and other items gets converted to gold. You can play Gnomes or Halflings for converting items to potions.
If you convert glyphs (the spells) you can get at least one potion for every spell.
