A ganodermic poncho is degrading high-level magic body armour that requires 75 Defence to wear. It is part of the ganodermic armour set. It can be made at level 98 Crafting by sewing 5,000 ganodermic flakes onto a mycelium poncho web, granting 1,000 Crafting experience. Creation (and repair) can be assisted.
The ganodermic poncho degrades over 30,000 charges of combat, and will revert into a mycelium poncho web when fully degraded. Partially degraded poncho can be repaired using ganodermic flakes - 50 per 1% - which also requires 98 Crafting and some thread, granting a scaled amount of Crafting experience. If they fully degrade, they will need to be re-created from the poncho web.
The poncho can be cleaned at any point to return the mycelium poncho web, and half of the remaining charges in ganodermic flakes, rounded up - e.g. an 80% charged poncho will return 2000 flakes. Additionally, alchemy performed on the poncho returns a scaling amount of coins based on the remaining charges.
