Hmm, something like, “spend 1 mettle as a bonus action, and an ally who can see and hear you can cast a cantrip that they know as a reaction. If they do, the weapon attacks of all allies in your presence deal the same damage as the cantrip until the start of your next turn. The ally casting the cantrip, or their target, must be within your Presence.”Maybe a small mettle spend (BA, not action) and an elemental cantrip, with the elemental damage matching the cantrip? That's neat.
