The Guthix max cape is a cape that is created by using a Guthix cape on a max cape. When the cape is created, the max hood that is required to be in the player’s inventory during the cape’s creation is automatically converted to the Guthix max hood.
Like the other max cape variants (a max cape combined with another cape slot item), the Guthix max cape does not have the max cape’s stats or perks; it only acts as a cosmetic upgrade to the Guthix cape. However, the cape can still be used to perform the skillcape emote.
Mac is able to refund a max cape, along with its variants, for 1,821,600 coins each, as long as the player has both the hood and cape in their inventory. It is important to note that capes combined with the max cape will be lost upon refund and will need to be earned again.
