Venenatis is a large poison spider that resides east of the Bone Yard, and is the only monster to drop the treasonous ring. She uses multi-target Magic and long-ranged melee attacks. She is able to drain Prayer as well as perform a highly lethal stun attack that can hit up to 50 damage, and may use the attack twice simultaneously, which is capable of instantly killing any player.

↑Only dropped while on a slayer assignment given by Krystilia, unless the kill was done on world 318, the official Bounty Hunter world. Killing Venenatis on world 318 also increases the drop rate from 1/27.5 to 1/5.
She was a player-suggested boss, which was adopted into the game after a substantial amount of positive forum feedback.
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 1-8 damage from the player's attacks regardless of their weapon. This is because her habitat is surrounded by 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 while standing in the single-way area if she remains in a multi-way area.
On release, the tree stump found south-east of the trees in 24 Wilderness was one square south than what it is now. This was changed in an update in order to prevent players safespotting Venenatis behind the trees. However, it can still be done, albeit with a lot more effort.
If Venenatis is lured south near single-way combat and attacks a player with her multi-target Magic attack, any nearby players in the single-way combat zone already in combat with another entity will also be hit. This may be an oversight by Jagex.
