Mystic smoke staff

The Mystic smoke staff is a members-only Old School RuneScape item — “It gives a 10% accuracy and damage bonus for spells on the standard spellbook.”. Its Grand Exchange buy limit is 8 per 4 hours. Right now it buys at 1,979,000 gp and sells at 2,000,000 gp — a net margin of -19,000 gp (-1.0% ROI) after the 2% Grand Exchange tax of 40,000 gp. High alchemy yields 25,500 gp.

To flip it, place a buy offer near 1,979,000 gp and a sell offer near 2,000,000 gp; the spread minus GE tax is your profit. Confidence figures are model estimates from live OSRS Wiki prices, not guarantees — flip responsibly.
