After some vague comments on Season Three Legendaries, all of which were immediately enabled (for seasonal and non) in Patch 2.2.0 on the PTR, the Blues have put together a complete list of which of the new Legendary Items will only drop for Seasonal characters, at least until the season ends.
Season Three Exclusive Legendary Items:
As with previously reworked Seasonal items, once patch 2.2.0 launches, these items will no longer drop in non-Seasonal games and will remain removed from the non-Seasonal Legendary pool until Season 3 concludes.
On a related note, we will be removing Bane of the Stricken from Patch 2.2.0. We’re not happy with its current implementation. It’s possible we may revisit it in a later patch.
I pasted the legendary affixes for all of the items into the Blue post, as I doubt many of us have memorized all the new powers just yet. Note that “rework” in the post means those are existing legendary items without useful legendary affixes, which are getting new powers and becoming seasonal items for S3. Subject to change during further PTR testing, obviously. (For instance, both guests on last week’s Podcast felt the Ob/Zod is now too powerful and probably due for a nerf to the proc rate.)
Also note that there are a lot of other legendary item changes in v2.2.0 that are not seasonal, and that the most impactful item changes in patch 2.2.0, the three new Item Sets and all the big changes to the vanilla class sets, are not going to be Seasonal and will be available for existing characters once the Patch 2.2.0 goes live after Season Two ends. Plus, changes to item sets are retroactive and will take effect on the green items you’ve already found, while you have to find new copies of the orange items to get their new legendary bonuses.
