Avatar of Destruction

The Avatar of Destruction is one of the two avatars in the Soul Wars activity. Both avatars have a Combat level of 525, making the two tie for the 8th strongest monsters in RuneScape. Along with having a maximum hit of nearly 500 Life Points, the avatar can also drain a player's Prayer. This avatar can be found on the red team's side of the battlefield. The required Slayer level needed to begin attacking this beast starts at 100 (meaning that no one can attack him, as the Slayer Cape cannot be brought into the battlefield), but as players add Soul fragments to the Soul Obelisk, the avatar's power will gradually diminish and this Slayer requirement will eventually reduce to 0. When members of the red team bury the bones of their fallen comrades or slaughtered enemies in captured graveyards, they will have a chance of increasing their avatar's Slayer Level.
