Black mace

The Black mace is a free-to-play Old School RuneScape item — “A spiky mace.”. Its Grand Exchange buy limit is 125 per 4 hours. Right now it buys at 900 gp and sells at 900 gp — a net margin of -18 gp (-2.0% ROI) after the 2% Grand Exchange tax of 18 gp. High alchemy yields 259 gp.

To flip it, place a buy offer near 900 gp and a sell offer near 900 gp; the spread minus GE tax is your profit. Confidence figures are model estimates from live OSRS Wiki prices, not guarantees — flip responsibly.
