Revenant

A revenant is a form of undead that is created when a powerful demon, usually that of desire or pride, possesses a corpse. Revenants have access to a few forms of magic, usually of a utilitarian nature, which assists with its primarily-martial fighting style.

Background

An entire unit of men, all slain by one creature. I didn't believe it at first, your Perfection, but it appears that this is so. We have a survivor, and while at first I thought his rantings pure exaggeration... it appears to be no simple skeleton. The descriptions of the creature's abilities were eerily similar to those our brothers at Marnas Pell encountered almost a century ago: men pulled through the air to skewer themselves on the creature's blade, and attacks so quick that it was able to assault multiple opponents at once. No, your Perfection, what we have here is indeed a revenant and nothing less.

Involvement

Dragon Age: Origins

There are two types of revenants encountered: one is considered undead, and thus has +75% cold resistance, -25% fire resistance, and is immune to nature damage. The other type is considered a demon, and thus has +50% fire resistance and +5% spirit resistance.

Eleven revenants can be found during the campaign, as a part of four separate quests:

The Black Vials - six boss-level revenants are trapped in glass phylacteries

Dragon Age: Origins - Awakening

It is possible to encounter revenants in Blackmarsh after escaping the Fade. Fade Portals will spawn various undead and demonic enemies, including revenants, though those that are encountered will be elite level and far easier to dispatch than the boss counterparts encountered in Dragon Age: Origins.
