Ultimate The Reach & Arkthzand Cavern Zone Guide

The Reach Area Description

Few adventurers choose to brave the rocky highlands of the Reach. Savage predators, perilous Dwarven ruins, and hostile Reach clans make it one of the least hospitable regions in all of Tamriel.

Arkthzand Cavern Area Description

The superstitious Reachfolk rarely speak of the dark caverns that lie beneath the surface of their sacred land. This willful ignorance, born from the wise belief that no good can come from unearthing what’s best left forgotten, has served them well since they first settled along the Karth River.

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.

ESO Delve Icon Map Image

On your map, delves appear with a blackened single torch.  Once the delve is completed (by defeating the boss or bosses), the delve icon turns white.

Voidmother Elgroalif at Four Skull Lookout

Travel northeast from the Rebel’s Retreat Wayshrine to locate the ruin called Four Skull Lookout.

Mechanics Notes

Voidmother Elgroalif summons Void Bombardiers and Void Horrors to aid her in battle.  She also summons Shades.  There are several aoes that you need to avoid but the largest one that can be devastating can be blocked if well timed.  Four Void Shields will appear and tether to the Voidmother.  During this time, she cannot be damaged.  You will need to quickly destroy these shields.  There will be a smaller circle that begins around the Voidmother that grows while the Void Shields are still active.  If that smaller circle reaches the larger circle, there will be a huge explosion.  You can block during this explosion and take a little bit of damage but if you aren’t aware, it will wipe you.  Focus on destorying those Void Shields as quickly as possible.  When they are all destroyed, her shield is down and you can damage her again.
