Level 4
You have learned how to steel yourself against a specific type of hostile environment. Choose one conditioning style from those listed below. You gain a +2 insight bonus to saving throws against the types of effects listed in any conditioning styles you have selected from this archetype. This is your conditioning bonus. If your conditioning bonus would apply multiple times to a single saving throw, instead increase your conditioning bonus by +1 for every time after the first that it would apply.
