pretty sure they wouldn't just unclick that armor-unit parameter just so hammers would stop working, that's just dumb and dirty.
meanwhile I'm trying to figure this out with my wip "don't talk to me or my sisters ever again team" consisting of elise, sakura, fcorrin, and azura ninian (don't have her, sob sob). Why do rods have to have crap stats AND do half damage. You'd think having higher than average res would mean you could at least survive magic attacks, but with such low health and >45 mag on average, you don't tend to survive those well either.
