Combat potion(3)

The Combat potion(3) is a members-only Old School RuneScape item — “3 doses of combat potion.”. Its Grand Exchange buy limit is 2,000 per 4 hours. Right now it buys at 116 gp and sells at 90 gp — a net margin of -27 gp (-23.3% ROI) after the 2% Grand Exchange tax of 1 gp. High alchemy yields 96 gp.

To flip it, place a buy offer near 116 gp and a sell offer near 90 gp; the spread minus GE tax is your profit. Confidence figures are model estimates from live OSRS Wiki prices, not guarantees — flip responsibly.
