DESC: Your races body produces a poison naturally. The poison can be released in 1 dose per successful attack and a user is limited to round(healthh/10) doses per day.
The target will make a save on the following round and each round after or maintain the effect and/or damage. This is not a magical effect and so can not be dispelled but must be cured or healed.
There are a number of different effects from real world poison but I have reduced these to 5 for game mechanics with a varied delivery method.
