The grifolic poncho is degrading mid-level magic body armour that requires 60 Defence to wear. It is part of the grifolic armour set. It can be made at level 78 Crafting by sewing 3,500 grifolic flakes onto a mycelium poncho web, granting 350 Crafting experience. Creation (and repair) can be assisted.
The grifolic poncho degrades over 30,000 charges of combat, and will revert into a mycelium poncho web when fully degraded. A partially degraded poncho can be repaired using grifolic flakes - 35 per 1% - which also requires 78 Crafting and some thread, granting a scaled amount of Crafting experience. If it fully degrades, it 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 grifolic flakes, rounded up - e.g. an 80% charged poncho will return 1400 flakes. Additionally, alchemy performed on the poncho returns a scaling amount of coins based on the remaining charges.
