Didn't the robot drop two black boxes on the ground before engaging them in combat? Even if the robot's buried, who's to say the boxes housing the relics are?If there's a round two, Kuhaku may be down for the count. He's already expended any carried ammunition for his weapon and his Semblance is reaching its limits. If the fight drags on any longer and he continues to strain and push himself, his Semblance will betray him and recoil back at him in a very nasty way. There's only so long his Semblance can fool his and Gren's own senses.

The things it dropped were just pieces of its limiters. That thing's a practice bot, but it was set to kill after they beat all the bots in the tunnel.
