Online:Delves

Barrow Trench

This page lists all the Delves in Elder Scrolls Online. Delves can be entered by anyone at any time, so you'll likely see other players in these locations, even if they are not in your group. Each one of these dungeons contains a Skyshard, so keep an eye out. Finding and defeating the final named enemy in each location earns you a 10 Point Achievement, and doing so in each dungeon within a zone earns you an additional 15 Point Achievement. There are usually 6 Delves in each zone (18 in Cyrodiil). Note that if you traverse the dungeon but do not take part in battle against the final boss, you will not get credit for the dungeon. If the boss has recently been killed, you may need to wait for them to respawn.

At release, delves were much smaller and consisted of a single linear, circular path. Updates 3, 4, 5, and 6 expanded most delves to their current size, but some base game delves still retain the old layout.

Group Delves in Craglorn function differently and are listed separately.

Notes

• Delve bosses respawn every 10–15 minutes. The boss will respawn instantly if a player without that delve's achievement approaches, although this does not result in any extra drops for players grinding that boss.
• Originally, delves in Cyrodiil behaved more like Public Dungeons, in that they had a very slow respawn timer and often multiple bosses. Unlike Public Dungeons, the number of bosses which would spawn at a time was limited, usually to one boss every fifteen minutes. This was intended to reduce boss farming and allow for better PvP interaction within the delves, but for those with multiple bosses it would mean a very large time investment should the wrong boss spawn several times in a row. This was changed in Update 19 (Patch 4.1.5) so that Cyrodiil delve bosses now spawn like in any other delves.
• Defeating a delve boss in Cyrodiil grants the Blessing of War buff for one hour.
