I've only just started playing Pixel Dungeon, but I always love rogue characters. I've found that putting ALL my upgrade points into his starter CLOTH armor makes him damned near impossible to hit, often dodging 5 or more blows in a row from super fast enemies. I'm talking evil eyes, scorpios, spinners, vamp bats, etc.. I know it goes against every rpg playing instinct, but seriously try it! I beat the game on normal once this way, and I'm easily at dungeon 12 now with 2 Anhks and more stuff than I need. 0 damage is much better than any plate absorbtion. Also, add to that a +2 evasion ring, and I barely ever get hit.
