Human Adaptability

As an errand action, you may refund an ability and choose to learn another ability. You cannot pick an ability that makes you ineligible for any of your prerequisites. Your new ability must cost the same as your unlearned one, or you must pay additional normal EXP to make up for the cost difference. If you choose to unlearn a class and learn a new one with this ability, you must spend IP for that new class as normal. Any previous IP spent on learning the class you unlearn is NOT refunded.

If you choose to refund primary stats, secondary stats or skill points and then level up the class again, you must put those points back in the same things you originally put them in.

Does not work on breakthroughs.
