The Seercull is a members-only Old School RuneScape item — “An ancient Fremennik bow that was once used to battle the Moon Clan.”. Its Grand Exchange buy limit is 8 per 4 hours. Right now it buys at 28,301 gp and sells at 33,035 gp — a net margin of 4,074 gp (14.4% ROI) after the 2% Grand Exchange tax of 660 gp. High alchemy yields 4,800 gp.
