Vexx monk hqdefault
The Old One-Eyed Monk of Nanyk is, as his name implies, a monk trapped in Daggercrag. Vexx helps him escape by defeating the many enemies in the temple.

Once Vexx does so, The Monk summons a Wraithheart as a reward.

He disappears in a flash of light once Vexx approaches, but can still be heard meditating.
