Alear's passive gives a guaranteed 3 true damage to all adjacent ally hits. Panette is a crit machine, that's her purpose, so she always does 3x damage. She's also fast, so she attacks 2 times. And giving her a brave axe makes her attack 2x per hit.
So 3*3*2*2=36. You then can use Seadall to dance her for another 36, then a Byleth ring to dance both of them for Panette to do a third 36, then Seadall dance her again for a fourth 36.
And Alear is a dragon, so if she's using the Lucina ring, she jumps in for a backup hit every time guaranteed. So every combat becomes like 40 damage. Deletes healthbars, especially since it's multiple combats.
