Buy OSRS Jar of spirits
The Jar of spirits is a rare drop from the Corporeal Beast in Old School RuneScape. This members-only item drops at a rate of 1 in 1,000 from the level 785 boss. It is tradeable, so players can buy it instead of grinding for the rare drop themselves.
The jar has one main use. Players can place it on a boss lair display in the Achievement Gallery of their player-owned house. This creates a display of the Corporeal Beast. To set up the display, a player must have killed the Corporeal Beast at least once.
The Jar of spirits is one of many boss jars in the game, like the Jar of dirt from the Kraken or the Jar of souls from Cerberus. Collectors like to gather the full set to show off in their house. The jar cannot be equipped and does not stack in the inventory. It weighs only 0.04 kg. The item was added to the game on 17 March 2021 and is tied to the Wilderness league region. It is a great pick for house builders and collectors.
