The revenant hellhound is a type of revenant. It is the undead version of the Hellhounds. It's more dangerous than its combat level might suggest. All revenants are capable of using all three corners of the attack triangle effectively. It can also restore life points rapidly and cure itself from poison a limited number of times.
As of 1 February 2011, revenants no longer patrol the Wilderness freely, and can only be found within the Forinthry Dungeon. The hellhound is at level 31 Wilderness in the Forinthry Dungeon.
Surprisingly, Hellhounds have a higher level than the revenant hellhound. Normally, the revenant version would be higher than the monster. This is probably because of Jagex's original intention for revenants to be a threat to players skilled enough to enter the wilderness, since for example, if a Revenant Dark Beast was level 182 like the normal version, the lowest level player it would be able to attack (prior to the 1 February 2011 update) is 126 (at level 56 Wilderness), making it a threat only to a select few players.
These revenants can be used for either Ghost or Hellhound slayer tasks.
The examine text on this Revenant has a mistake similar to the Revenant vampyre. When reading the examine text of this revenant, it says "The essence of a hellhound slain during the God Wars." However, the term essence in this text would mean their non-revenant verisons would have a 100% drop of ashes of any sort, but their 100% drop are Bones instead. The same also affects the Revenant vampyre.
Despite the fact they are slain hellhounds from the God Wars, Revenant hellhounds have a lower combat level compared to regular and God Wars hellhounds, but hit much more higher then them.
