Buy OSRS Demonic skin contract
The Demonic skin contract is a members-only item in Old School RuneScape. It lets your character change skin color to red. This is a rare cosmetic look that few players have.
To use it, take the contract to the Makeover Mage. The Makeover Mage lives south-west of Falador. Give the contract to the mage to unlock the demonic skin color. After that, your character can wear the red skin look.
This item comes from the Leagues Reward Shop, where it is called a Demonic skin sample. It is tradeable, so players can buy and sell it. It is not stackable, but it can be noted. It weighs only 0.1 kg and cannot be equipped. You can read it or drop it. Its item ID is 33302.
The Demonic skin contract is a good pick for players who want a bold new look. Red skin makes your character stand out in banks, at the Grand Exchange, and in group content. Since the unlock is tied to the Leagues Reward Shop, this cosmetic is a nice way to show off in game.
