[X] Take Command - This will replace your Action for the turn and risk escalating the matter, as well as weaken you elsewhere. Still, you are the best commander in the Clan bar none, and you are confident that with your personal intervention the war will be easily won. Don't take the field directly, though - keep yourself off the field for a potential counterstrike against enemy Nascent Souls.
[X] Draft a new Protostrator - There are no true excellent candidates, but plenty who could be well-tempered. Get the best Core Formation Elder and raise them to Protostrator. You'll need to do this eventually, and this will give them plenty of experience. It is likely to draw out the war, though, and command will be difficult as they will need to accustom themselves to their new position mid-war.
[X] Take the Field - As Take Command, but do take the Field. If no Nascent Soul comes to oppose you, you can wrap this war up neatly and quickly. Very high risks of escalating to Nascent Soul combat, though.
