Oi! Swarming is Deskari's signature move!

Abramo despises locusts, but he's not above stealing an effective tactic. That's not the sort of property he respects - and anyway, inter armes silent leges. At least that part of the law that protects "signature moves".

...and eventually, it's Arueshalae who lands the decisive blow.

It hardly matters. It was a team effort; she couldn't have done it without Sosiel's Breath of Life keeping Nenio in the fight; without the hail of Maximized Bolts of Justice that weakened the demon lord; without the mass buffs that kept the worst of the acids and locusts off her aim. Or the mass of nameless elementals and Azata that rushed in bravely to their permanent deaths and kept him busy while the named characters landed their named attacks.

...or without Arueshalae's bow. Recognising everyone's contribution means including herself, too.
