Poison (Ex): An opponent hit by a drow’s poisoned weapon must succeed on a DC 13 Fortitude save or fall unconscious. After 1 minute, the subject must succeed on another DC 13 Fortitude save or remain unconscious for 2d4 hours. A typical drow carries 1d4–1 doses of drow knockout poison. Drow typically coat arrows and crossbow bolts with this poison, but it can also be applied to a melee weapon. Note that drow have no special ability to apply poison without risking being poisoned themselves. Since this poison is not a magical effect, drow and other elves are susceptible to it.
