If you have a claw attack (either from an actual natural weapon or from an effect such as claws of the beast), you can use this power to produce a mild venom that coats one of your claws. On your next successful melee attack, the venom deals 1 point of Constitution damage per round for 2 rounds. A target struck by the poison can make a Fortitude save each round to negate the damage and end the affliction.

Augment For every 3 additional power points you spend, the poison’s duration increases by 1 round.
