This game is kind of interesting. Your power is almost entirely determined by your equipment, and when you level up your fighting or armor skills, you actually level up your ability to equip better items.
The extra speed starting ability seems so strong as to be broken, but I took the infravision one for the sake of convenience.
Each enemy type on each floor apparently has randomly assigned weaknesses, resistances, and immunities, so if you do zero damage to everything, that's why - it's possible for them to be completely immune to hand to hand attacks .
