- A hat - Either a leather cowl, wizard hat (blue) or wizard hat (black)
- A body - Either a leather body, cape (random colour), or a priest gown (top)
- A weapon - Either a bronze sword, bronze 2h sword, bronze scimitar, bronze longsword, bronze warhammer, or a bronze battleaxe.

The items that player gets cannot be selected; the player will randomly get one item from each category.
