Dark cavalier

The Dark cavalier is a members-only Old School RuneScape item — “All for one and one for all!”. Its Grand Exchange buy limit is 4 per 4 hours. Right now it buys at 2,000 gp and sells at 2,185 gp — a net margin of 142 gp (7.1% ROI) after the 2% Grand Exchange tax of 43 gp. High alchemy yields 120 gp.

To flip it, place a buy offer near 2,000 gp and a sell offer near 2,185 gp; the spread minus GE tax is your profit. Confidence figures are model estimates from live OSRS Wiki prices, not guarantees — flip responsibly.
