I'd say Far Song (from the replacement blacksmith in Redcliff) for a Cunning Rogue, or in general for a Character in need of additional attack rating. For a Dex Rogue or one with enough att the better Choice is probably Sorrows of Arlathan (reward item from Witch Hunt). These are the best ones for the warden in DAO, i think. A Good Early Bow would be in Haven (merchants house). Its in a locked Chest (not in the backroom), so no fighting. You only would need to have the mapmarker and a good enough rogue (its a 50exp chest i think).
