Buy OSRS Jar of decay
Description
The Jar of decay is a rare item from Old School RuneScape. It drops from Vorkath, the dragon boss on the island of Ungael. The drop rate is 1 in 3,000 from the post-quest version of Vorkath at level 732. That makes it a hard item to get on your own.
The main use for this jar is in your player-owned house. You can use it on a boss lair display in your achievement gallery to make a display of Vorkath. To build the display, you also need to have killed the stronger form of Vorkath after finishing Dragon Slayer II at least once.
The jar has one more trick. If you use most types of bones on it, the jar eats them. The chat box says the bones decay into nothingness. The jar's own description says it is "Very healthy."
The Jar of decay weighs 0.04 kg. It is tradeable and noteable, but you cannot equip or stack it. It is a great pick for players who collect boss jars or want to show off a Vorkath display without waiting on a rare drop.
