Toxin Adaptation

Your body quickly adapts to toxins, especially if you willingly expose yourself to them.

Prerequisite(s): Great Fortitude, Craft (alchemy) 5 ranks

Benefit: When you make a Fortitude save to resist poison, you become immune to future doses of that poison for 24 hours. Additionally, if you voluntarily expose yourself to a poison which you craft yourself, you get a +2 bonus on your Fortitude saves to resist the dose, and you become immune to that type of poison for a number of days equal to your ranks in Craft (alchemy). In either case, you become immune to future doses whether your saving throws succeed or fail.
