How to flip the Aether catalyst
The Aether catalyst is a members-only Old School RuneScape item — “A piece of the cosmos' soul? Or souls belonging to the cosmos?”. Its Grand Exchange buy limit is 25,000 per 4 hours. Right now it buys at 272 gp and sells at 290 gp — a net margin of 13 gp (4.8% ROI) after the 2% Grand Exchange tax of 5 gp. High alchemy yields 120 gp.
To flip it, place a buy offer near 272 gp and a sell offer near 290 gp; the spread minus GE tax is your profit. Confidence figures are model estimates from live OSRS Wiki prices, not guarantees — flip responsibly.
