Okay, let's see can Will survive this combat round :P. Use 3.5 DnD variant for mass taunt all monsters in area to focus attacks on Will for 1 round. It's mind affecting ability which asks will save 16 from everyone. I doubt even disciplined those orcs will saves do not grow big and in most best case scenario around half charge Will (and break formation) or all they charge and leave archer's exposed (as they need to clutter and surround Will and so leave space for others reach archers). Top of all if archers fail, they are firing shots which likely only critical hit would only hit Will. I doubt fiendish woman falls for Will's taunt but who knows. At least everyone got bless spell in which is bread and butter for group buffs in skirmish figths.
