Vrock

From Planescape: Monstrous Compendium Appendix I (1994):

Vrocks are an elite fighting force used in important battles [in the blood war]. They are often sent on missions such as infiltration and other covert missions.

Vrocks eat their fallen foes after combat. They are powerful fighting machines from birth. Vrocks are loyal to their own. They travel in groups of up to eight (more when entering battle) and in battle coordinate with each other with perfect timing.

Combat: Vrocks are never surprised and always attack first in melee. These creatures have Strength 19 (+7 damage adjustment) and infravision to 120’. Vrocks are immune to attacks from nonmagical weapons.

Vicious fighters, the vrocks can attack five times per melee round. Because of their dexterity and extreme battle prowess, vrocks can direct each of these attacks against different opponents. Their hand claw attacks each inflict 1d8 damage. Their beaks inflict 1d6 damage per successful hit. Vrocks can also attack with their foot claws, inflicting only 1d4 damage because the vrock is off balance when attacking this way.

The vrocks also attack with a stinging ejection of spores from small glands about the creatures’ bodies. They can attack once every three melee rounds with a spore attack. A spray of spores automatically inflicts 1d8 damage on all opponents within 5 feet. Once the spores have hit, they implant themselves just below the surface of the skin and begin to grow and sprout. Victims suffer 1d2 damage per round from spore growth. The spores continue to grow for 10 melee rounds, at which time the victim is covered with thick, vine-like growths. The spores can be killed by a bless, neutralize poison, or similar spell or by being sprinkled with holy water. Slow poison stops the growth.

Once per battle, a vrock can emit a loud, deafening screech. This screech deafens everyone within 30’, stunning them for 1 round (Constitution check to avoid the stun). Vrock usually save their screech for emergencies and typically use it when near death, screeching just before they teleport away.

In addition to those available to all tanar’ri, vrocks have the following spell-like powers at 10th level of spell use: detect invisibility, detect magic, dispel magic, mass charm, mirror image, and telekinesis. They can attempt once per day to gate in 2-20 manes, 1-6 bar-lgura, or 1 nalfeshnee. There is a 50% chance of success.

When five or more vrocks fight together in battle, they can attempt a special power called dance of ruin. The vrocks join hands in a circle, then dance wildly, screeching and chanting in ancient languages. After three rounds, a weave of energy crackles and scintillates in the air like lightning. Anyone within 100 feet of the dance of ruin must save vs. death magic or suffer 2d20 damage (save vs. spells for half damage). If any vrock takes 20 or more points of damage during the three melee rounds, the dance is disrupted and must be started again. All creatures, including the vrock, are affected.

From Dungeons & Dragons Monster Manual (2014):

Vrocks are dull-witted, capricious fiends that live only to create pain and carnage. A vrock resembles a giant hybrid of humanoid and vulture, its gnarled, bestial body and broad wings stinking of offal.

Vrocks gobble humanoid flesh whenever they can, stunning potential prey with an ear-splitting shriek, then swooping down to attack with beak and claw. Vrocks can shake their wings, releasing clouds of toxic spores.

Coveting pretty things, vrocks turn against each other for the chance to lay claim to cheap jewelry or ornamental stones. Despite their love of treasure, vrocks are difficult to bribe, seeing no reason to bargain when they can simply take what they want from a would-be bargainer’s corpse.
