Vial of Spiders

Wondrous item, common

This palm-sized vial is filled with exactly 888 tiny spiders. The spiders magically obey the verbal commands of the last person to open the vial.

Too small to harm Tiny or larger creatures, the spiders have little use in combat, but can be used as sentries, to creep people out, or to keep a small house clear of insects. New spiders grow in the bottle at night, so that 888 spiders always exist at a time.
