Grifolic leggings are degrading mid-level magic leg armour that require 60 Defence to wear. They are part of the grifolic armour set. They can be made at level 72 Crafting by sewing 1,200 grifolic flakes onto a mycelium leggings web, granting 120 Crafting experience. Creation (and repair) can be assisted.
The grifolic leggings degrade over 30,000 charges of combat, and will revert into a mycelium leggings web when fully degraded. Partially degraded leggings can be repaired using grifolic flakes - 12 per 1% - which also requires 72 Crafting and some thread, granting a scaled amount of Crafting experience. If they fully degrade, they will need to be re-created from the leggings web.
The leggings can be cleaned at any point to return the mycelium leggings web, and half of the remaining charges in grifolic flakes, rounded up - e.g. 80% charged leggings will return 480 flakes. Additionally, alchemy performed on the leggings returns a scaling amount of coins based on the remaining charges.
