Vaelastrasz the Corrupt is a red dragon and the second boss in Blackwing Lair. He has become enslaved by Nefarian and begs players to put him out of his misery before he kills them. One of World of Warcraft's original DPS checks, Vael puts a debuff called Burning Adrenaline on raid members that eventually kills them, regardless of immunities or health. This served as a soft enrage back in the day.

This NPC can be found in Blackwing Lair.
