I think it'd really invigorate the game if y'all added rarity above Legendary. Name wise, I was thinking you could go with Mythic, Ancient, Ascended or Godly. Imagine crafting Godly Flip-Flops lol.
Then for color, I feel like red is an obvious choice, but orange or hot pink could be fun too. Or maybe even a radiant white?
Finally, you'd likely have to adjust success chances across the board to craft one of these, but I was thinking that only players level 65+ or even 70+ even have a chance to craft this tier, as who could make a Mythic or Godly item on accident. You need experience.
An alternative would be this new tier only unlocks once you've successfully crafted each previous rarity tier. Buying from the market wouldn't count!
Thanks for your time and would love to hear y'alls thoughts!
