Looking for mod component: Mage can use Crossbows?

About six months ago I played through BGEE (after 2.0 and SOD launched) using Big World setup and I know I checked some component that let Mages become proficient with and equip Crossbows; however, looking through the hundred or so components of BWS for my next play through I can't seem to find it anywhere and I can't remember what larger mod it was a part of. I though it may have been Tome and Blood or one of the other Mage overhauls but I can't seem to find it. Does anyone remember what mod this was?
