This gives you the Ghoul Rank in game & the Duskull Hood Hat. You can see an image of the Duskull Hood Hat by viewing the image below, equip it in game by using /cosmetics and clicking the Duskull Hood Hat! The Ghoul Rank grants a Black -> Purple chat gradient in game when equipped. 
You can equip your rank in game by doing /ranks, clicking Cosmetic Ranks and scrolling over to Ghoul Rank. You CANNOT equip two ranks at once. If there's any issues, feel free to open a Ticket on our Discord describing the issue.
