Binding Mastery

Prerequisite: Ritual Caster feat, mastery of Magic Circle and one other binding ritual
Benefit: When interacting with creatures that have an origin other than natural, you can use Arcana or Religion in place of Diplomacy and Intimidate. You also gain a +2 bonus to Arcana checks or Religion checks made for this purpose. Once per day, you can ignore the component cost of a binding ritual of your level or lower that you have mastered.
