Hairy spider

Hairy spiders are vicious black hunting spiders that are found in jungles, tombs, caverns, and throughout the UnderWorld. Though they spin no webs, they can move readily in the webs of other spiders, and they are immune to all known spider venoms.

Hairy spiders hunt in groups, swarming over victims to bite. They are remarkably resistant to crushing damage; rolling or crashing into walls is ineffective at removing or destroying hairy spiders. They must be individually struck or torn away.

Hairy spiders are sometimes used as familiars, especially by drow wizards. They can carry small items and walk on walls and ceilings; they have 60-foot infravision and are not afraid of fire.

Note: Hairy 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.
