Demon Hunter

Demon Hunters, disciples of Illidan Stormrage, uphold a dark legacy, one that frightens their allies and enemies alike. The Illidari embrace fel and chaotic magics - energies that have long threatened the world of Azeroth - believing them necessary to challenge the Burning Legion. Wielding the powers of demons they’ve slain, they develop demonic features that incite revulsion and dread in fellow elves.

Illidari Training

You are adept in the training required of one of the Illidari, Illidan's demon hunters. You gain proficiency with Revenant Double-Bladed Scimitars. You gain the Blind Fighting fighting style. 

You can fall at a speed of 20 feet per second, and if you do, you don't take fall damage due to temporary demonic wings. 

The Hunt

You've sacrificed much to become a Demon Hunter, netting you powerful bonuses against fiends. When attacking fiends, your melee attacks have advantage, you deal and additional 2d6 sneak attack, and you land a critical hit on 19's. Once per long rest, you can mark one creature you can see.
