I think that INT is already strong enough for the chanter, more duration for invocations and more aoe both phrases and invocations. Resolve needs to be able to make longer linger: "Resolve reflects a character's internal drive, determination, fearlessness, and the emotional intensity they can project to others. It can be useful for mental intimidation, leadership, and convincing performances. In combat, it helps characters maintain Concentration and contributes to the Will and Deflection defenses." More pathos in my words!
