Tales of Tolgard
This creature looks like a cross between a vulture and a human. It has strong limbs covered with small gray feathers, large feathered wings, and a vulture head on the end of a long neck. A vrock is about eight feet tall and weighs about 500 pounds.
Vrocks are vicious fighters who like to fly down into the enemy and cause as much damage as possible. They prance about in battle, taking briefly to the air and bringing their clawed feet into play. Despite their advantage in mobility, the vrocks’ deep love of battle frequently leads them into melee combats against heavy odds.
To use their dance of ruin ability, a group of at least three vrocks must join hands in a circle, dancing wildly and chanting. After dancing for a short while, a wave of crackling energy flashes outward in a 100-foot radius which does extensive damage to all non-demons. They also can cast mirror image, telekineses, and greater teleport at will.
A vrock can release masses of spores from its body periodically. The spores automatically deal damage to all creatures adjacent to the vrock. They then penetrate the skin and grow, dealing an additional damage each round for about a minute. At the end of this time, the victim is covered with a tangle of vine-like growths.
