Hi, I'm not sure whether this has been asked before, but when creating an attack on the PF character sheet, there are the usual options, Melee Ranged and CMD, as well as BAB Full for when you have to fiddle around with the modifiers. Then there's also a BAB Max option, which if I change the attack to, it doesn't change anything, but I'm assuming it's there for a reason. Does anyone know what's it's purpose?
