Buy OSRS Ancient emblem
The Ancient emblem is a members item in Old School RuneScape. It is a mysterious artifact from ancient times. Revenants in the Revenant Caves drop it. It is tradeable and noteable, but you cannot wear it or stack it.
The main reason players want this emblem is coins. You can give it to the Emblem Trader, who wanders the Revenant Caves, and get 500,000 coins for it. This trade only works on the official Bounty Hunter world. The Emblem Trader in Edgeville will not take it.
There is a second use too. You can use a chisel on the emblem to break it into 1,000 revenant ether. Ether is useful for players who fight revenants or charge wilderness weapons.
Be careful with this item. It is always lost on death, even if it is the only item in your inventory. Being skulled raises the drop rate from revenants, but a skull from a high-risk PvP world does not count.
Higher level revenants, like the dragon and knight, drop the emblem more often than low level ones like goblins and imps. It can also come from Bounty crates.
