Legendaries : not yet implemented, supposed to be rare and strong gear, more than uniques.
Uniques :There are already a lot of them. They give special effects. You can check the wiki.
Set items : a bit like uniques but have set buff depending of how many items from the set you have.
Normal gear : can have up to 4 affixes, 2 suffixes and 2 prefixes. Each affixe has a tier from 1 to 5 (5 is the strongest). Affixes can be found on the gear when it drops but you can also add affixes or upgrade their tier through crafting.
Perfect sounds good. I’m a still a big fan of the D2 loot system. Yea I know builds became samey with rune words(never seem any game get close to these.
Think will definitely be picking up. Is there going to be a demo launched with beta or is that planned later?
