Under the Iron Sky
Dagger of Venom
This +1 dagger allows the wielder to use a Poison spell-like effect upon a creature struck by the blade once per day. The wielder can decide to use the power after he has struck. Doing so is a free action, but the poison effect must be invoked in the same round that the dagger strikes.
The poison deals 1d3 Stamina damage per round for 6 rounds. Poisoned creatures can attempt a DC 14 Fortitude save each round to negate the damage and end the affliction.
