Silt Spider

A swarming nest of tiny pale spiders barely distinguishable from the shifting silt that is their home, these creatures rush towards you in a single heaving mass.

Combat
A silt spider swarm seeks to surround and attack any living prey it encounters. It deals 1d6 points of damage to any creature whose space it occupies at the end of its move.

Description
Silt spiders are tiny creatures that dwell in Athas‘ silt seas and basins. Easily able to camouflage themselves within and swim though the silt, they are a hazard wherever they are encountered. Although their bite and accompanying poison is not overly dangerous, their sheer numbers often mean that a target will be devoured by the swarm before he has a chance to regain consciousness. Individual silt spiders rarely reach six inches in size but can swarm in scores or hundreds.
