Items:

There seems to be a ton of new unique effects being tested out mostly on rings however i’d imagine there not being 50+ legendary rings coming out in the expansion so some might be migrated to weapons and such and are just being tested using the rings.

There is just tons more information that is mostly in gibberish strings that may or may not make sense to some people so I’m going to avoid posting that here. However if you wish to take a look feel free to head to the link at the bottom of this post and jump into the Diablo 3: Reaper of Souls rabbit hole and see how much info you can get out of it… theres more info there dealing with things such as enchanting, quests, backstories, transmog, paragon bonuses and, SO SO much more.
