I can vouch for this. I played in a campaign as a Warlock. The party found the illusionist bracers; but all we knew was the name, not the functionality. I piped in, "My warlock specialized in deception (he's a fortune teller by trade), so I imagine something to do with illusions would be helpful." The party agreed and I strapped them on. I became a walking cannon. The campaign ended shortly afterwards because of the imbalance. —
