After becoming poisoned, sick, plagued, diseased, or any other health effecting status ailment, except burns and other such physical problems, the character can develop an immunity to the status ailment. When effected make a Resist check. If you pass after you are infected, then your character will develop an immunity chance of 20% to that particular infliction. Each time you succeed at the check for that affliction, your character's immunity chance increases by 20 until your character is completely immune, no longer being able to be inflicted by the same infliction. This must be done for every new infliction of any new health affecting status ailment, including beneficial ones, and happens despite player or character will. This is a permanent effect.
Having this talent lowers your Will when resisting mind, mental, or psychological affecting status effects and attacks, such as fear, by 20 points.
