Yes, Mira, you can use a hold from Dance of Blades to give a +1 to any allie on any move!  However, there's no need at all for you to do it with Ari at this moment, Aribeth has full authorial control as far as this NPC is concerned!<br/><br/>I know, this feels SUPER weird, but it's okay! NPCs with knives to your throat get the same advantage ;D
