—From Codex entry: Rage Demon
Rage demons are encountered in 2 varieties: Critter-ranked lesser rage demons and Normal or Lieutenant greater rage demons. Besides having more health and dealing more damage, the latter also possess several additional abilities. Both types, however are immune to Fire damage, but have have Cold vulnerability, to the point where a single Winter's Grasp might instantly kill a lesser version at full health. Like all demons, they're immune to stun and knockback/knockdown effects. However, they can be shattered and unlike abominations, they have normal reaction to Nature damage.
The rage demons faced in the Fade can be dealt with effectively in either the Spirit or Burning Man forms, as the Spirit form has Winter's Grasp and the Burning Man form provides virtual immunity to all their attacks.
- Both types:
Greater rage demons only:
- A boss-level greater rage demon can be fought at the end of the Watchguard of the Reaching quest. He doesn't gain any new abilities when compared to regular Greater Rage Demons.
- Often, rage demons will rise up from the floor of the room, invisible (and un-targettable until they do so). At death, they always sink back in, with a small black circle of (presumably) their essence appearing during the process. This process leaves no loot (although in some quests) a lootable white sack appears.
