Tiers of items will now be basic, advanced, superior, relic, mythic, legendary, and unique, but the devs are quick to point out that higher tier items aren’t always necessarily the most powerful; they trend in that direction but “unique” is mostly used to identify an item that has a distinct property or effect for example. The addition of categories also opens up the potential for new item variants that can be made from crafting, and the devs discuss the challenge of getting mythic items as an example.
