I used an all out sub formation to clear all the maps....there is no reason why you can't.

Else, just field a decent fleet composition if you have the resourcs to spare. If you have spare bauxite, you can field CVs to help clear trash mobs....if not, field a fleet formation that only use fuel and ammo. BBs and CAs and maybe a single DDs to attract enemies that don't target subs to attack her instead of your other fleet. Enemies love attacking DDs.

Or if or else fails/resources lack, you really should try fielding a all sub formation and makes sure Iona is equpped with two torps for her to trigger cut-ins and placed at the bottom of your fleet composition. That's how my Iona one-shots all the event bosses.

Good luck and god speed.
