I don’t like save-or-die poisons. Here are a couple of quickies that give your PCs a little more time to act or react.
Save or collapse on the ground from loss of breath. Target will lose 1 HP each round until dead. A Save is permitted at the beginning of each round to end this effect.
Choking Poison may be applied to a bladed or piercing weapon or consumed.
Save +2 or be -1 to-hit and AC until one hour after the last dose of Crippling Poison was received. This effect stacks if hit by more doses.
Crippling Poison must be applied to a bladed or piercing weapon.
