So just wanted to clarify the 13th level Thief ability to use any magic device regardless of race or class. RAW seems pretty straightforward on this but just to make sure, a rogue can use a Holy Sword? Robes of the Archmagi? Anything? Reason I'm asking is I was going to have an NPC who passes himself off as a wizard, but really he's a rogue who managed to stumble upon a fantastic cache of magic items left from a long dead wizard. Wands, robes, Iron flasks, that sort of thing. He basically does high end magic shows and then robs powerful people, although I'm not 100% sure exactly what his end game will be but it sounded like an interesting idea I'd like to run with.
