Leonel met the eyes of the Half Spiritual, his gaze not giving anything away, though he knew the reality of the matter. If they fought a battle like this one, casualties would be inevitable, and not just casualties that he could just casually revive either, true, final death casualties.
It would take too much time for the war to end, and by that point, damaged Ethereal Glabella or not, the end result would be the finality of death. There wasn't much he could do about this. This was the reality of a war you weren't prepared for, and the striking difference was stark in comparison to the war he was prepared for.
The decision would be in the hands of the Half Spiritual Overlord, but no matter how you looked at it, he didn't receive the kind of benefits he wanted from this battle.
