Or convert the AF into a key item that gives you a trait that enhances your ability.

For example, convert Drachen Armet+1 into a key item called Drachen Soul: Head which when you are a DRG, grants you a trait called "Drachen Attunement" which allows breaths to be activated at 50%. These can be set like atma and would only apply to AF1+1 and AF2+2
