This gives you the Samurai Rank in game & the Samurai Helmet Hat. You can see an image of the Samurai Helmet Hat by viewing the image below, equip it in game by using /cm and clicking the Samurai Helmet Hat! The Samurai Knight Rank grants a Red -> Yellow 'Sunset' chat gradient in game when equipped.
You can equip your rank in game by doing /ranks, clicking Cosmetic Ranks and scrolling over to Samurai 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.
