Zodar

In the Dungeons & Dragons fantasy role-playing game, the zodar is a fictional humanoid ("medium-sized construct"), which is incredibly powerful and rather enigmatic.

When a zodar chooses to fight, it will do so (usually) without any weapons, preferring to slam and grapple their opponents, rather than punch and/or kick them.

Zodars have many unique powers as well. Three times a day, for a few seconds at a time, a Zodar can increase its strength. Zodars are also immune to many effects such as poison, stunning, and disease. They also can only be damaged by bludgeoning weapons. A zodar's ultimate ability is that once per year it can cast a wish spell to alter reality as it sees fit.

Typical physical characteristics
Approximately 5 feet tall, zodars appear as ornate black suits of armor with a life of their own; these "suits" are not actually made of metal, but rather a ceramic material. They are capable of speech which all sentient beings are able to understand, though despite this unique linguistical proficiency, they hardly ever speak more than one sentence every 50 years or so.

Alignment
Zodars are usually of the chaotic neutral alignment.
