Mystic dust staff

The Mystic dust staff is a members-only Old School RuneScape item — “It's a slightly more magical stick.”. Its Grand Exchange buy limit is 8 per 4 hours. Right now it buys at 25,000 gp and sells at 45,000 gp — a net margin of 19,100 gp (76.4% ROI) after the 2% Grand Exchange tax of 900 gp. High alchemy yields 25,500 gp.

To flip it, place a buy offer near 25,000 gp and a sell offer near 45,000 gp; the spread minus GE tax is your profit. Confidence figures are model estimates from live OSRS Wiki prices, not guarantees — flip responsibly.
