Necromancer Healer Build
Necromancer healer builds are incredibly potent in The Elder Scrolls Online. They have some of the strongest area heals in the game, and can provide amazing group utility with valuable buffs and debuffs. They excel in using fallen enemies against remaining foes, and can even bring their allies back from death in an instant! Necromancer healers are excellent to have in your group in ESO.
Gear Sets
Spell Power Cure: One of the best healer sets in the game, Spell Power Cure will help to boost the damage output of your team by a huge amount. You can get this from White Gold Tower, and is worth the investment.
Pillager's Profit: This is a powerful set that allows you to transfer ultimate to your entire team - and a lot of it! You can get this from Dreadsail Reef, and it is well worth the investment.
Baron Zaudrus: Necromancers already have excellent ultimate regeneration with the Necrotic Potency skill. By also using Elemental Susceptibility and adding in Pillager's Profit, you can feed ultimate to your whole group quickly and efficiently, massively boosting damage output.
Perfected Grand Rejuvenation: Helping further with providing resources back to your group, this set will boost the Stamina and Magicka Recovery of any team member within the AoE by a lot, making it a valuable item. You can get this from Veteran Dragonstar Arena.
Skills
Illustrious Healing: A strong healing over time ability that affects a decently sized area, and returns resources back thanks to the staff we use.
Combat Prayer: This is primarily used to provide the Minor Berserk and Minor Resolve buffs to your group, boosting damage output and survivability.
Radiating Regeneration: A cast-and-forget skill that allows you to apply sticky healing to your group members that will last a lengthy duration.
Renewing Undeath: This is an incredibly useful skill that applies instant healing to everyone in a decently sized area, consuming a corpse to also purge them of their negative effects.
Spirit Guardian: Primarily used to keep the Undead Confederate passive active, granting you additional recoveries. Also provides healing to you or nearby allies, and 10% damage mitigation to yourself.
Glacial Colossus: Your ultimate of choice for providing Major Vulnerability to enemies in a wide area for a long duration, which is a massive DPS boost for your whole group.
Elemental Blockade: Provides a projectile shield to your allies along with snares, immobilizations, Chilled and Brittle to your enemies.
Elemental Susceptibility: With the Baron Zaudrus set, you can spam this skill to provide a huge amount of ultimate back to your party.
Blighted Blastbones: While Blastbones provides a nice boost to DPS, even though you are the healer, it is actually used to provide corpses at the target location that you can use to empower Renewing Undeath.
Unnerving Boneyard: This is a flex slot, and can be switched out for single boss fights. Boneyard is used to provide Major Breach to all enemies within the area.
Energy Orb: Your allies will be able to activate the synergy on this moving healing orb to restore resources to themselves.
Reviving Barrier: When things go south and you need to save your group, this will do the trick. Use it to get out of a tricky situation, or power through intense mechanics.
Champion Points
Soothing Tide: This perk grants a substantial power boost to your area healing abilities, allowing you to strategically place healing area spells where they are needed most.
Swift Renewal: Healing over time abilities are some of the most common you will use on a healer, and this will boost their healing power substantially.
Hope Infusion: The ability to grant Minor Heroism to allies is a very useful boon to you and your group. Every time you heal an ally below 50% health, you will grant them Minor Heroism for one second per 300 Magicka Recovery that you have.
Enlivening Overflow: Similar to Hope Infusion, you can grant resource recovery to your allies based on how high your Max Magicka is, up to 150.
Boundless Vitality: Every bit of health makes a difference, especially in some of the tougher content that The Elder Scrolls Online has to offer. This will help you bump yours up a little more, increasing your survivability.
Fortified: Similar to Boundless Vitality, one can never have enough resistances, and this will add a little extra to boost your survivability so that you can focus more on the task at hand.
Rejuvenation: Recoveries are important for every role. For healers, it is essential for keeping your group alive, for tanks, it is the source of most of your buffs and debuffs, for DPS, you can't deal damage with no fuel, and in PvP, no resources means death.
Celerity: Extra movement speed is an amazing boost in all content. In PvE, it helps massively with avoiding nasty mechanics, and in PvP, it allows you to run circles around your opponents.
Mundus Stone
The best Mundus Stone to use on this build is the Thief. Good healers are adepts at stacking up plenty of healing over time so they can focus on individual targets or on buffing instead, and critically healing boosts healing power massively. However, if you have enough critical chance, use the Mage for more max Magicka, or Atronach if you need more recovery.
Food Buff
The Ghastly Eye Bowls food buff is typically the best option for any PvE Magicka character. It offers the best combination of Max Magicka and Magicka Recovery. If you are in content that requires higher health, you can use the Withmother's Potent Brew or Clockwork Citrus Filet if you prefer.
Race
The best race to use for this build is a Breton. This is the best race in ESO for Magicka sustain, but the Argonian is also a good option.
Potion
Spell power potions will offer this build access to the valuable Major Sorcery and Major Prophecy buffs, both of which will boost your healing power by a lot. You also get the much needed Magicka return, and a long boost to your Max Magicka.
Mortality
The benefits of being a Vampire or Werewolf are not worth the drawbacks on this build. Therefore, it is strongly recommended that you remain a Mortal with this build to ensure you don't run into issues.
Notes
Necromancers are unique qualified to generate a lot of ultimate, and between Pillager's Profit and Baron Zaudrus, that can be used to provide incredibly high uptime on Major Vulnerability, buff your group and debuff your enemies very effectively. You can even switch in Necrotic Potency in fights with a lot of adds, allowing you to generate ultimate at a crazy rate. All of this comes with incredible healing potential that will keep your group alive through the toughest content.
