What Is A Crafting Set Station?

A crafting set station is a crafting area that allows you to craft a specific set piece of armor.  Often there are additional requirements, like a number of traits that must be researched before you can make an item of a specific set.  While you can make generic pieces at crafting set stations, these are the only areas where you can the specific set that is listed.  There is one exception – attunable crafting tables (which are ‘tuned’ to replicate set stations) can be obtained and placed in houses for use.

ESO Map Icon Crafting Set Stations

On your map, crafting set stations appear with a blackened crafting icon when you are close to a location.  Once the set station has been visited, the icon turns white.

What Is A Delve?

A delve in The Elder Scrolls Online is in essence a small dungeon.  Delves usually contain a few enemies, at least one ‘boss’, and a skyshard.  Delves can generally be completed solo.   If you are a new player, you may want to explore delves with a friend.  Most delves have an associated quest that you can get just inside or near the entrance.  This quest is more a side story to the main quest of the area but does offer rewards for completing it.
