The Elder Scrolls Online site has been updated with a brief preview of the new content coming in the Scalebreaker DLC and Update 23 in August. Scalebreaker will include a pair of new PvE dungeons called Moongrave Fane and Lair of the Maarselok. All players will receive Update 23 that includes the much-requested "multi-crafting" utility that allows players to craft, deconstruct, and refine multiple items at one time.
The Scalebreaker DLC will soon be released in the Crown Store as a separate purchase. It is included in ESO Plus membership.
Other additions in Update 23 include multi-bidding for Guild Trader locations; Undaunted Keys & rewards are being updated; and Ald Carac and Istirus Outpost have been updated.
