Ideas for a leprechaun race:

• Gets unlimited gold-stealing attacks that allow you to teleport each time you steal gold from a monster’s inventory or beneath their feet, which allows you to set up teleportations in advance by luring a monster onto a pile of gold pieces. Stealing gold gives +1 alignment record.
• Has weak attribute maximums.
• Can enchant any boots to +7.
• Has naturally better AC from being smaller, or instead you sometimes automatically leap and evade in response to an incoming attack.
• Rigid body armor won’t fit because of the small size.
• Luck either starts temporarily at +1 or times out permanently to +1.
