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 115 gp and sells at 300 gp — a net margin of 179 gp (155.7% ROI) after the 2% Grand Exchange tax of 6 gp. High alchemy yields 42 gp.

To flip it, place a buy offer near 115 gp and a sell offer near 300 gp; the spread minus GE tax is your profit. Confidence figures are model estimates from live OSRS Wiki prices, not guarantees — flip responsibly.
