Oathplate shards

The Oathplate shards is a members-only Old School RuneScape item — “A strange metal from a distant realm. It has long since lost its luster.”. Its Grand Exchange buy limit is effectively unlimited. Right now it buys at 139,000 gp and sells at 139,222 gp — a net margin of -2,562 gp (-1.8% ROI) after the 2% Grand Exchange tax of 2,784 gp. High alchemy yields 600 gp.

To flip it, place a buy offer near 139,000 gp and a sell offer near 139,222 gp; the spread minus GE tax is your profit. Confidence figures are model estimates from live OSRS Wiki prices, not guarantees — flip responsibly.
