Execution Powder

The spores of a certain mushrooms, if carefully collected and suspended in a properly mixed alchemical fluid, can kill those near death. If a creature is reduced to 0 Hit Points while under the effect of execution powder, it must succeed at a DC 34 Will save or die (this is a Death effect). If a creature dies from execution powder, the spores from their last breath alight on a random creature adjacent to the victim, granting that creature 20 temporary Hit Points and a +1 status bonus to attack and damage rolls for 10 minutes.

Saving Throw DC 34 Fortitude; Maximum Duration 6 rounds; Stage 1 7d6 poison damage (1 round); Stage 2 9d6 poison damage (1 round); Stage 3 12d6 poison damage (1 round)
