A new five-dungeon adventure pack is on the way for the game and is in fact being tested right now. The devs said that this pack doesn’t contain a single narrative arc but instead is “tied thematically around wizards run amok.” We can get behind that.
The patch also contains the new Falconer enhancement tree, which will give an avian combat pet to any character that wants one: “It is designed to provide fewer big hits; the hunting bird swoops to attack seconds after you have made your weapon attack to provide extra damage and certain status effects.”
Favored Soul and War Priests are due for a revamp with this update, and Barbarians are going to be seeing their fair share of changes as well.
