There are no classes in Brogue. There are no races. There is only you and the dungeon and the things in the dungeon.
Who you become is up to you. It depends on how you identify equipment, what you put your enchantments into, what weapon and armor you protect against corrosion, and what equipment you leave behind on the dungeon floor. Rather than class or race, we talk about kits and builds. Here are a few.
Most characters end up as mix of these, but the components of these builds cooperate particularly well.
