A spider swarm seeks to surround and attack any living prey it encounters. A swarm deals 1d6 points of damage to any creature whose space it occupies at the end of its move.
Any living creature that begins its turn with a spider swarm in its space must succeed on a DC 11 Fortitude save or be nauseated for 1 round. The save DC is Constitution-based.
Injury, Fortitude DC 11, initial and secondary damage 1d3 Str. The save DC is Constitution-based.
A spider swarm has a +4 racial bonus on Hide and Spot checks and a +8 racial bonus on Climb checks. It uses its Dexterity modifier instead of its Strength modifier for Climb checks. It can always choose to take 10 on a Climb check, even if rushed or threatened.
