The Boneguard was an enemy encountered during the Enakhra's Lament. It was an enchanted creature, bound to guard Enakhra's Temple against its will. It attacked the player with melee, and the Crumble Undead spell had to be cast on it to defeat it, after which it would turn into a Freed Spirit and thank the player. Players could then climb over its bones.
As the spell was removed with the Evolution of Combat, the Boneguard no longer makes an appearance, but the Pile of bones it left behind is still present.
Another Boneguard appears later in the quest, which is revealed to be Akthanakos. Like the other boneguard, he was altered with the release of the Evolution of Combat. Previously, players had to use protect from melee to block his attack before he would converse with players.
