Fungal leggings are degrading low-level magic leg armour that require 25 Defence to wear. They are part of the fungal armour set. They can be made at level 12 Crafting by sewing 1,000 fungal flakes onto a mycelium leggings web, granting 50 Crafting experience. Creation (and repair) can be assisted.
The fungal 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 fungal flakes - 10 per 1% - which also requires 12 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 fungal flakes, rounded up - e.g. 80% charged leggings will return 400 flakes. Additionally, alchemy performed on the leggings returns a scaling amount of coins based on the remaining charges.
