Feat: Cantorian Reinforcement

The life energy that helped create the first hobgoblins is particularly potent in you, protecting you from ongoing maladies. If you roll a success on a saving throw against a disease or poison, you get a critical success instead. If you have a different ability that would improve the save in this way (such as the Battle Hardened fighter class feature), if you roll a critical failure on the save you get a failure instead.
