The ganodermic visor degrade over 30,000 charges of combat, and will revert into a mycelium visor web when fully degraded. 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 they fully degrade, they will need to be re-created from the visor web.
