Combat mix(2)

The Combat mix(2) is a members-only Old School RuneScape item — “Two doses of fishy combat potion.”. Its Grand Exchange buy limit is 2,000 per 4 hours. Right now it buys at 100 gp and sells at 225 gp — a net margin of 121 gp (121.0% ROI) after the 2% Grand Exchange tax of 4 gp. High alchemy yields 63 gp.

To flip it, place a buy offer near 100 gp and a sell offer near 225 gp; the spread minus GE tax is your profit. Confidence figures are model estimates from live OSRS Wiki prices, not guarantees — flip responsibly.
