I dont really know much about addy armor droppers, but from the monsters i have killed from slayer tasks, i have seen black dragons and greater demons drop some addy stuff. usually the only monsters to drop addy armor are tough so i would recomend you just buy it from other players or the grand exchange.
Any armour you can buy on the Grand Exchange is legitimate.
