Superior Zuriel's robe bottom is degradable tier 88 magic legs power armour. It is made by upgrading Zuriel's robe bottom with an Ancient warriors' equipment patch. This increases its tier from 78 to 88, and makes it augmentable. This process is irreversible, and the upgraded item cannot be traded, even if it remains unused. Superior Zuriel's robe bottom degrades to dust over 100,000 charges of combat. It cannot be repaired, and when it runs out of charges it vanishes.
