Actually, you’d be better served using high dodge guys than typical tanks, even without FM, as lost souls do damage directly to HP regardless of armor. If you’re only fighting LS and have the chance to re equip, it’s actually best to go in naked for extra fatigue and initiative (pay no attention to my screenshots not showing this in action :P).
I don’t think that’s needed though, as Lost Souls drop so easily. And they are not really that hard to hit at least in my experience, since I’ve got a lot of Perfect Focus/Battle Flow characters with very high Melee/Range Skill.
