Stench (Ex): The stink of death and corruption surrounding a crawling slaughter is overwhelming. Living creatures within 30 feet must succeed on a DC 17 Fortitude save or be sickened for 1d6+4 minutes. A creature that successfully saves cannot be affected again by the same crawling slaughter's stench for 24 hours. A delay poison or neutralize poison spell removes the effect from a sickened creature. Creatures with immunity to poison are unaffected, and creatures resistant to poison receive their normal bonus on their saving throws. The save DC is Charisma based.

Web (Ex): A crawling slaughter can create a web three times per day. This ability is similar to an attack with a net but has a maximum range of 50 feet and a range increment of 10 feet. A web attack is effective against targets of up to one size category greater than the crawling slaughter. Upon a successful hit, the web anchors the target in place, allowing no movement. The crawling slaughter cannot create a sheet of web like a normal monstrous spider can.

A creature entangled in a crawling slaughter's web can burst it with a successful Strength check (DC 32) or escape with a successful Escape Artist check (DC 32). Both are standard actions. [he DCs are Constitution-based (+0 due to a lack of Constitution) and include a +10 racial bonus.

Single Actions Only (Ex): Much like a zombie, a crawling slaughter has poor reflexes and can perform only a single action in a round. Thus, it can either move or attack, but it can do both only if it charges.

The crawling slaughter follows what ever simple instructions it receives from its creator or controller. It is capable of following directions such as, "March forward and destroy all dwarves you encounter."

The crawling slaughter is an enormous undead creature created from the remains of a monstrous spider. Although not venomous, the crawling slaughter drips fetid goo from its orifices as it lumbers across the landscape. The creatures horrific stench foretells its approach for hundreds of yards, and it leaves a trail of slime and rotting lumps of flesh behind it.

The crawling slaughter is often found in the company of drow, serving either as the centerpiece of a warband or occasionally as a mount for a powerful drow cleric. In the latter case, the drow commands the creature with a large spiked ankus. A crawling slaughter feels no fear, no joy, no want, and very little pain - it exists only to destroy the enemies of its master.
