In fact, there’s a new build up this week in case you’d like to get an advance preview (and help stomp out some bugs, of course). The biggest change is the addition of tier 2 difficulty for the new instance cluster. Standing Stone Games has also adjusted lootbox gear, increased the power of crafted potions, and bumping up the danger level of mid-level monsters.
If you missed it, you can get a preview of the new Dwarven zones coming in Update 23, thanks to a series of videos straight from the test server.
