Jar of stone detail.png

The jar of stone is a rare drop from the Grotesque Guardians that can be found on the Slayer Tower's rooftop.

The jar can be used on a boss lair display in a player's Achievement Gallery to have a display of the Grotesque Guardians. Doing so requires killing them at least once.

  • Upon release, the jar of stone could not be used on the boss lair display, due to the graphics being incomplete. This was added in an update two weeks later.
