Venenatis is a large spider that resides east of the Bone Yard, and is the only enemy to drop the Treasonous ring. She is able to drain prayer points and perform a highly lethal special attack that can hit up to 50 damage, and may use the special attack twice simultaneously, which is capable of almost instantly killing players. She was a player suggested boss, which was adopted into the game after a substantial amount of positive forum feedback.
Like God Wars bosses, Venenatis is unable to be frozen.
The term Venenatis comes from the Latin "Venēnātis" which means "Venomous" or "Poisoned".
If Venenatis is attacked while she is in a single way area, she will only take 1-6 damage from the player(s) attacks regardless of their weapon. This is because her habitat is in a single way area, and all of the Wilderness bosses (excluding demi-bosses) reside in multi-way areas. Players can still deal full damage to her in the single way area if she is lured into a multi-way area.
