Topic says it all really. I bought Magic Weapon and put it into my attunement slot. I have the stats to use it, but when I take out a catalyst and try casting my character just looks at the staff funny and scratches his head. It's weird, but I can cast things like soul arrow with no problem. For some reason Magic Weapon is also darkened no matter what I do, the way other spells are when you don't have the item used to cast them equipped. I really have no idea what I'm doing wrong. Can anyone explain how the spell is cast?
Bear in mind I'm feeling kind of stupid here, level 60-some-odd and I still have no idea how to work this basic spell.
