Demon hunter
Demon hunters are dark, shadowy warriors who are shunned by the greater night elf society. They made a pact, long ago, to fight against the forces of chaos using its own terrible powers against it. These mysterious warriors ritually blind themselves so that they develop 'spectral sight' that enables them to see demons and undead with greater clarity. They wield demonically charged warblades in battle and even call upon demonic energies to augment their formidable combat skills. Although they are counted as some of the mightiest warriors within the night elves' society, the demon hunters are always maligned and misunderstood for making their selfless pact with darkness.WC3MP 56 Though many among the night elves and the Alliance fear the demon hunters and their pact with darkness, all know that demon hunters and their demonically-charged warblades have played an important part in combating what remains of the Burning Legion.
Background
Illidan Stormrage is the most famous demon hunter, and was the first of their kind. Even Illidan's own brother did not appreciate his sacrifice, and locked him below ground for thousands of years for trafficking with dark powers. Illidan's case was unique. Sargeras, lord of the Burning Legion, burned away Illidan's eyes with magic fire until only scorched sockets remained. Illidan's resulting sight was a maddening display of violent colors. His altered vision allowed him to easily recognize both demons and mortals with magic powers. In addition, Sargeras covered Illidan's body with black tattoos that increased his arcane power.
Later, a group of night elves, inspired by Illidan's example, made a pact to turn the Burning Legion's powers against it, fighting destruction with destruction. Obviously they could not gain their powers in the same way Illidan did, but they discovered other means. In the millennia since, other night elves, and a few creatures of other races, have made the same pact, binding demonic essence in their bodies and using it to destroy the Legion's minions.
Development & Abilities
Demon hunters have a variety of abilities that assist them in destroying demons, though the power coursing through their bodies also allows them to prevail over lesser foes. Demon hunters eschew heavy armor, valuing mobility and speed. As a demon hunter grows in power, they undergo a gradual evolution, becoming more and more demonic in appearance. The changes are cosmetic and can take many different forms, from burning eyes to black blood. By the time the demon hunter reaches the pinnacle of his development, he is a twisted and dark version of his former self - though the chaotic energy in his body does not affect his personality and allegiance (or so the demon hunters claim), it wreaks great changes on his physical form. The demon hunter’s gradual evolution achieves its pinnacle as they become a demonic entity. Their appearance has changed to something frightening: The exact changes vary, but can include glowing red eyes; horns; clawed feet and hands; nonfunctioning wings; cloven hooves; a spiked tail; dark skin; a deep, rumbling voice; and similar cosmetic changes. The demon hunter becomes an outsider.
The demon hunter can drain a demon’s energy to fuel their own powers. They mainly use arcane and fire energy. Shadow energy is rare. No other energies have been confirmed. The demon hunter can channel the chaos energy within them into a melee weapon to increase its powers. In time the demon hunter becomes more proficient in channeling demonic energy into their weapons, and highly skilled demon hunters are adept at this technique. Demon hunters have shown the ability to cover their bodies in a shell of flame. At the pinnacle of evolution, Demon hunters can unleash the demon in them and turn themselves (temporarily) into something more. This is called Metamorphosis.
Demon hunters hone their speed and maneuverability to overcome their foes.
