Venenatis is a large spider that resides in the Silk Chasm, at level 35 Wilderness.

According to Phabelle Bile, Venenatis is the last of her kind, who were hunted to extinction by dwarves.

A dwarf multicannon cannot be set up in the Silk Chasm; if attempted, you will receive the message: It doesn't seem safe to set up a cannon here.

Ironmen are eligible for drops from Venenatis when defeating it alongside other players.

In order to enter Venenatis' lair, the player must have completed the medium Wilderness Diary tasks, OR they must have a Venenatis boss Slayer task (a spider Slayer task does not bypass the diary requirement).

Venenatis attacks with melee towards any player that's adjacent to her, and either magic or ranged for any player out of her melee range. Protection prayers will fully block the attacks, however, they will have their effectiveness reduced for every spiderling alive in the chamber.

Every four attacks, Venenatis will shuffle to another position in her lair. Every two movements will cause her to alternate between ranged and magic attacks.

When a kill starts, Venenatis begins by summoning two spiderlings, who also increase her max hit along with reducing prayer effectiveness. The spiderlings will drain prayer by 1 for every hit made regardless if it damages or not, however they only have 5 health and players will deal their max hit on them regardless of gear. Venenatis can also launch a sticky web that if stood on, damages and drains prayer by 3 and run energy by 10 every few ticks. Venenatis will always alternate between the spiderlings and the sticky web after moving around twice.

If there are more than 10 players in Venenatis' lair, she will move more often and perform a special attack every time she moves, as opposed to every other time.

The following money making guide is available for Venenatis:

Method	Hourly profit	Skills
Killing Venenatis	5,950,220	80+ 80+ 70+ recommended for Piety

Drop rates are estimated based on 60,120 samples from the Drop Rate Project, unless otherwise cited.

The listed quantities are for soloing Venenatis. In group encounters, Venenatis's drops, including uniques, will be split proportionally based on damage done. Up to 10 players may obtain drops per kill in this manner, and each of the top 10 players will receive at least 25% of the solo loot quantity.

Ironmen must deal 7% of the overall damage to be eligible for 25% of the solo loot quantity. Ironmen dealing less than 7% damage will receive a minimum of 5% of the solo loot quantity.

The average solo Venenatis kill is worth 246,174.83. This increases marginally to 247,887.93 on a Konar task, or 248,648.47 on a Krystilia task.

The effective drop rate for a unique (fangs, pet, voidwaker gem, or treasonous ring) is ~1/95.24.

From her release to 25 January 2023, Venenatis could be found roaming just north of the green dragons on the eastern shore of the Wilderness and was the only one of the bosses she was released with to be below level 30 Wilderness. She only attacked with melee and magic and had two mechanics; a prayer drain on her target and could also launch sticky webs at them that could deal up to 60 damage and briefly stun them. Venenatis also had a unique damage reduction mechanic in part that she would only take 1-6 damage from any hit if she was in a single-way area, as the area was partially multi and single combat zones.

• Concept art of Venenatis' Silk Chasm, by Mod Jerv.

• Venenatis' 2014 model was a recoloured version of Kalrag.
• 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 "venēnātīs", which means "venomous" or "poisoned".
• Despite her name's origin and Phabelle Bile mentioning Venenatis does indeed produce venom, she and her spiderlings are not venomous or poisonous to players. This is leftover from before the Wilderness boss rework, when her attacks inflicted poison.
• If someone starts a battle with Venenatis, but leaves the cave without killing her, she will de-spawn after 10 minutes.
