All Duergar posess natural psychic abilities, their gift allows them to enlarge to great size or become invisible at will.
The feared Duergar Mind Masters have honed these abilities even further, and operate as spies and truth-seekers both within and outside Duergar society.
The Mind Master can see through any illusion, and can reduce their size down to just a few inches in height. During this transformation, their mind becomes a focused instrument more deadly than any smithed weapon. A prick from their needle sized dagger sends shooting psychic pain through their enemies, and by the time their enemy understands what’s going on, the Mind Master disappears as quickly as a rat.
