Neverwinter's module 1 update, also known as Fury of the Feywild, will hit the game next Thursday, August 22nd, but you don't have to wait until then to read up on all of the specifics. Cryptic has posted many of the patch's details today, although they are of course subject to tweaking.
Expect to see a lot of changes with module 1, including many class balance adjustments, a reduction in cost for some astral diamond purchases, a new passive power for non-augment companions, better inventory management, foundry tag searches, and LFG and trade chat channels.
Fury of the Feywild will also include the new high-level zone of Sharandar, the ability to upgrade companions with astral diamonds, the salvage feature, and the new professions of artificing and weaponsmithing. The patch will also lay the groundwork for the Summer Festival to begin on August 29th.
