This build was created by and will be explained by Yicky, an ESO content creator, the first setup is a Beginner's gear setup:
This guide is about the way that I run my Necromancer tank in Normal/Veteran Dungeons and Normal Trials. This is a CP160 build so I will be recommending Dungeon/Trial gear to be best effective. There are many different trial builds when it comes to end game and moving into high end vet content. This is the setup that has worked well for me when it comes to completing said content.
First off for attributes I go for a balanced Health/Magicka build. The Necromancer can be very magic heavy on the skills so building this out still gives you more than enough health w/ food buff and a decent Magicka pool. Adding Spirit Mender to your skill rotation will also increase your Magicka regen.
You can use a bit more Stamina in this build, however it is much quicker to use heavy attacks with your front bar Sword & Shield than swapping to your back bar to try to regain Magicka.
You can typically use any Race for this tank spec. Some races may have stats that you may desire or not, so feel free to check out ESOU's guide on Racial Passives and the last guide on tank Races by Nefas.
Choice of food will depend on your playstyle/stats but the most popular tank food tends to be Bewitched Sugar Skulls.
Recommended Mundus Stone will be The Lord or The Lady.
Recommended Potions will be Essences of Health that give back Magicka, Stamina and Health.
This is a step up from the beginner setup introduced earlier on this build page.
Saxhleel is another raid set from Rockgrove, and this set is a good one because of the Necro ultimate regen.
Effectively you can replace Aggressive Horn for another ultimate like reanimate if you have this build as the ultimate use provides the same buff. For some instances, such as off-tank, you can run Saxhleel and Arkasis for even faster ultimate regen and fire off your ultimates more often.
Encratis’s Behemoth is a very good set for dungeons where flame damage is primary, but even if it isn’t, the set is still strong because it increases enemies flame damage taken as well. An alternative would be Earthgore but it can be difficult to acquire. If Earthgore is out of your reach, The Troll King can be a good alternative as it is similar, but instead of removing effects and creating a direct heal, Troll King increases the health recovery of the target. Smaller heal, but still helpful.
