I know that feats have usrCandid fields beyond 2 and don't show, but what should I do for a feat that needs 3 selections? Normally I would bootstrap a helper ability, but they don't seem to have usrCandid fields. I know the Headband of Vast Intellect bootstraps a special wonderous item to select its 3rd skill, do I need to do something similar and have a special feat?
