Briar used his own power to test what was in the bags. Crushed dried plants. Well then, perhaps he would be more use than he'd expected in what the unfamiliar mage attempted. "Give me just a minute."

He wrapped his magic around the contents of each bag, strengthening the ingredients. They regained the power that fresher plants would have, reminded of what they had once been. Briar took pains to do so in equal measure for each in order to maintain the balance necessary for whatever use she intended to put them to. He might not be much help for the actual spell, but he could make it easier for her to cast. "Alright, whenever you're ready."
