PF2: Corrupted Spider

Corrupted Spider

I mentioned in the PF 1e version of the Corrupted Spider that I have not made monsters in quite some time. So that is something I’m going to try to do for a while: make PF 1e and 2e versions of the same monster. This monster is obviously based on the hunting spider, but I increased the challenge rating and themed it to be more demonic. Tell us what you think in the comments below.

Spring Upon Prey [Reaction] (attack); Requirement Initiative has not yet been rolled. Trigger A creature touches the corrupted spider’s web while the spider is on it. Effect The corrupted spider automatically notices the creature and Strides, Climbs, or Descends on a Web before it rolls initiative.

Corrupted Spider Venom (poison); Saving Throw Fortitude DC 20; Maximum Duration 6 rounds; Stage 1 2d6 poison and flat-footed (1 round); Stage 2 2d8 poison, enfeebled 1, and flat-footed (1 round); Stage 3 2d10 poison, enfeebled 2, and flat-footed (1 round).
Descend on a Web 1 (move) The corrupted spider moves straight down up to 40 feet, suspended by a web line. It can hang from the web or drop off. The distance it Descends on a Web doesn’t count for falling damage. A creature that successfully Strikes the web (AC 22, Hardness 4, 6 HP) severs it, causing the spider to fall.
Web Trap A creature hit by the corrupted spider’s web attack is immobilized and stuck to the nearest surface until it Escapes (DC 22).

The overwhelming majority of creatures that find their way to the Abyss end up either ripped apart by demons or other denizens for pure enjoyment. Those that not only survive but thrive in this environment for generation after generation end up changed by it, becoming one of the horrors of this dreadful place. Vermin are most often the creatures that undergo this change with spiders being the undisputed masters of being foul creatures that survive this change. 

While they are no smarter than their mundane counterparts, corrupted spiders are larger, stronger, and more deadly than those found on the Material Plane. Even worse, they gained some of the protections that the creatures native to this plane possess. Generations of these creatures feasting upon demons will impart their natural biology upon them. They still remember their taste for humanoid flesh and will ensnare such prey at their first opportunity.
