Revenant vampyres are a type of revenant, lost souls of vampyres that died in the God Wars.
As of 1 February2011, revenants can no longer patrol the Wilderness freely. They are now only found within the Forinthry Dungeon, which is a PVP-enabled area. They used to have a longer respawn time than any other revenant in the Forinthry Dungeon. As of 22 July2014, the revenant vampyre's respawn time is the same as that of the other revenants in the Forinthry Dungeon.
Like all revenants, they can restore health quickly, can cure themselves of poison and react quickly to a player's protection prayers. In addition, they seem to have the slowest respawn rate out of all the revenants in the dungeon.
WARNING: The Forinthry Dungeon is a PVP-enabled area, meaning it is entirely possible for other players to attack you whilst fighting the revenants in the dungeon. Do not bring equipment that you are not willing to lose.
Revenant vampyres take the longest time to spawn of all revenants, even longer than revenant goblins. Although the revenant goblins respawn rate was drastically changed to meet that of other revenants' spawn rate, the revenant vampyre's spawn rate was not.
