yes, being a mage just means you can summon magic circles to conduct your magic energy through and give it form, everyone else who isn’t a mage can still possess magic energy control, but only to a small degree (which is why most powerful fighting style/weapon users aren’t even aware they are imbuing magic onto their attacks as “aura”, as the boxing mentor says)
i mean yeah why wouldn’t they be able to, if its in lore its not like they aren’t allowed to pick up a weapon or something
