Our defensive layers comes in the form of Fortifying our massive Life pool, stealing health from enemies, and having access to Blood Orbs which will heal us. This build is entirely designed around Blood Surge to clear packs of enemies & for single-target. Thanks to the massive amount of Life and Fortify we have on this build, the damage dealt by Overpower on our skills skyrockets, as Overpower provides bonus damage based on the sum of your current Life and Fortify. Building corpses is one great way to get the upper hand.The Blood Surge Necromancer build, also known as the “Bloodmancer”, provides a sturdy, resilient and high damage dealing character for you to start your adventures in Diablo 4.

That is one of the strengths of the Necromancer, causing a ton of damage and being able to heal and use his dead enemies against the others. A useful skill with a dual purpose, Bone Armor can absorb damage and causing it at the same time which comes in handy when getting surrounded. This will allow less damage to get to the Necromancer and throw out skills like Simulacrum and Gift of Death. This is also true of the other summoning spells but they should be used more as distractions as the Necromancer should pump out more damage worthy skills. Using summoning spells like Skeletal Mage, for the most part, attacks only one enemy at a time but it's extremely powerful when upgraded. Another skill to hone in on is Siphon Blood with Power Shift for tons of damage and healing. Pair it with Close Quarters and it becomes a damage machine. With all the corpses laying on the ground, one of the best skills available in a Necromancer's arsenal is Corpse Explosion.
