Be sure to check out this solo Vampire Magicka Necromancer build, prepared especially for the Blackwood chapter in The Elder Scrolls Online. Necromancer builds are especially strong as you are practically impossible to kill due to the strong survival skills of this class.
This is very helpful for people who like to play solo. The Blackwood chapter, due to the introduction of new things such as companions, will be favorable for solo play in ESO.
