Staff of the dead

The Staff of the dead is a members-only Old School RuneScape item — “A ghastly weapon with evil origins.”. Its Grand Exchange buy limit is 8 per 4 hours. Right now it buys at 5,701,000 gp and sells at 5,864,000 gp — a net margin of 45,720 gp (0.8% ROI) after the 2% Grand Exchange tax of 117,280 gp. High alchemy yields 600,003 gp.

To flip it, place a buy offer near 5,701,000 gp and a sell offer near 5,864,000 gp; the spread minus GE tax is your profit. Confidence figures are model estimates from live OSRS Wiki prices, not guarantees — flip responsibly.
