|A power emanates from the crystal.|
The keystone crystal is obtained from the other side of the tightrope in the deathly room within the Chambers of Xeric. Players must defend against deathly rangers and deathly mages. Once obtained, players can open the barrier while carrying it.
It is recommended to kill some of the deathly rangers and mages before crossing the rope to obtain the crystal, as they can hit extremely high.
