You exude a mild contact poison through your pores.

Prerequisite: Entobian.

Benefit: Any creature that makes a successful unarmed or natural attack against you takes one point of Constitution damage. You can turn this ability on and off as a free action. Entobians and any creatures immune to poison are immune to this effect. The damage is cumulative per hit, and wears off all at once, three rounds after the last point of Constitution damage was received.
