The Remnant of Zebak is an item obtained from the Tombs of Amascut raid. It is used on the Tumeken's guardian pet to allow it to metamorphose into Zebo.
In order to receive one from the reward chest, players must complete a raid at level 450+ with zero deaths for all party members, whilst having all invocations for Zebak enabled. Furthermore, players must defeat him at path level 4 or higher.
