The archers ring is one of the Fremennik rings and is dropped by the Dagannoth Supreme in the Waterbirth Island Dungeon. The Fremennik rings are some of the very few rings in RuneScape to give stat bonuses, and the Archers’ ring is considered to be the best ring for rangers to use.
It can be imbued using 650,000 Nightmare Zone reward points, which doubles its bonuses.
