Buy OSRS Jar of chemicals
The Jar of chemicals is a rare item from Old School RuneScape. It drops from the Alchemical Hydra, a level 426 boss in the Karuulm Slayer Dungeon. The drop rate is 1 in 2,000, so this jar is hard to get on your own. Buying one saves you many hours of boss fights.
Players want this jar for their player-owned house. You can use it on a boss lair display in your Achievement Gallery. This creates a display of the Alchemical Hydra in its final form. You must have killed the Alchemical Hydra at least once to set up the display.
The jar is light at 0.04 kg. It is tradeable and noteable, but you cannot wear it or stack it. It also has a fun side. If you use the jar on another player, a message says they do not want to drink something with that many chemicals in it.
This item is a great pick for collectors and house builders. It shows off your win over one of the toughest Slayer bosses in the game.
