Large spider
From Ardrana
Large spiders are web-spinners that build strong, sticky webs, and often lurk nearby waiting for victims to get stuck while examining the beautiful constructions of their own spinning. As many spiders as possible will attack the defenseless victim during its struggle to free itself.
Note: Large spiders originally appeared in this form in the 2nd Edition Monstrous Manual for the AD&D game from TSR. Their use here is for the purposes of providing context for the campaign only.
