A ganodermic visor is degrading high-level magic head armour that requires 75 Defence to wear. It is part of the ganodermic armour set. It can be made at level 86 Crafting by sewing 500 ganodermic flakes onto a mycelium visor web, granting 100 Crafting experience. Creation (and repair) can be assisted.
The ganodermic visor degrades over 30,000 charges of combat, and will revert into a mycelium visor web when fully degraded. A partially degraded visor can be repaired using ganodermic flakes - 5 per 1% - which also requires 86 Crafting and some thread, granting a scaled amount of Crafting experience. If it fully degrades, it will need to be re-created from the visor web.
The visor can be cleaned at any point to return the mycelium visor web, and half of the remaining charges in ganodermic flakes, rounded up - e.g. an 80% charged visor will return 200 flakes. Additionally, alchemy performed on the visor returns a scaling amount of coins based on the remaining charges.
