Laws of Deterministic Dungeon:
1.) When there is ever a chance for treasure I shall roll a 0 or shield. Whichever is possible and worse.
2.) Whenever there is a possibility of a monster, I shall roll at least 3.
3.) Whenever there is a special chest. I shall only roll scrolls I already have.
@Koda - I wonder that too. People don't go on to jobs that are worse than their previous jobs. If so they quit. You have to wonder what they did before to make this "a step up".
You can only enchant/craft the best weapons/armor by working skill as librarian, then going to school as tailor or smith. Even w maxed skills you only have a 25% chance each time you try and risk 2k of gold. But thats how you beat the red dungeons.
