Radiant Visage

Radiant Visage was a skill used by the Monk in Diablo III. It was seen in pre-release gameplay, but was removed from the released product.

Radiant Visage causes the Monk to release a nova of pure golden light from his body. Enemies that are caught in the light are temporarily blinded, rendering them helpless for several seconds. If attacked while blind, they will become alert again, although their chance to hit is nearly halved.

Blinding Flash skill in the released version of the game, in fact, incorporates the same idea, but is seemingly more effective.
