Black warlock (item)

The Black warlock (item) is a members-only Old School RuneScape item — “There's a black warlock butterfly in here.”. Its Grand Exchange buy limit is 125 per 4 hours. Right now it buys at 175 gp and sells at 285 gp — a net margin of 105 gp (60.0% ROI) after the 2% Grand Exchange tax of 5 gp. High alchemy yields 42 gp.

To flip it, place a buy offer near 175 gp and a sell offer near 285 gp; the spread minus GE tax is your profit. Confidence figures are model estimates from live OSRS Wiki prices, not guarantees — flip responsibly.
