According to a post on Elder Scrolls Online website by game director Matt Firor, the ESO Update 5 is currently on public test servers and is ready to be tested right now.
Firor shared some details regarding update 5 and stated that players should expect a new veterun dungeon along with a new facial recognition system which will improve how NPC’s look during a conversation.
The update will also fix some known issues of player separation during a quest in a group. The main highlights for update 5 are as follows:
A new Veteran Dungeon: City of Ash continues the dungeon’s story and introduces dangerous new challenges for your group.
The new facial animation system makes NPCs far more lifelike during conversations. Repeatable Pledges: The Undaunted now reward players once a day for specific dungeon runs with special loot and trophies.
Repeatable Writs: You’ll be able to obtain certification in your crafting skills and then complete Writs for inspiration, materials, and special Survey Reports that will lead you to high-yield harvesting nodes.
Dungeon level scaling: Dungeons’ enemies and rewards will scale to the level of the group leader, giving you more chances to group up, experience a challenge, and get appropriate rewards.
More player separation fixes: More quests will be streamlined so you aren’t separated from your group members as often while adventuring.
Furthermore, Matt Firor also stated that a part from these features and fixes, the update would add a new item set for crafting, a new Dwemer crafting style and chat bubbles.
