The Necromancer class in Diablo IV offers a variety of playstyles, and one of the most powerful upgrade strategies is the Blood Wave DoT build. This build centers around utilizing the Blood Wave ability to gradually drain enemy health through a DoT effect. This ability is most effective when combined with other Necromancer abilities and Diablo 4 Items . Therefore, this build requires a relatively diverse item set.

The Blood Wave DoT build effectively combines DoT effects with the Necromancer's ability to summon troops and dominate the battlefield. The Blood Wave ability releases blood energy, dealing permanent damage to enemies. When paired with special items and passive abilities that enhance DoT effects, it acts like a ticking time bomb, continuously draining enemy health without requiring constant monitoring.

Item selection is crucial to the effectiveness of this build. Prioritize items that enhance DoT effects, extend Blood Wave's range, and reduce its cooldown, significantly increasing its damage output. Additionally, Legendary items that increase minion survivability or provide bonuses to Bloodtide can boost overall damage and survivability. Finding a balance between offense and defense is crucial, especially in the challenging encounters of the Abyss.

Your skill allocation should prioritize the synergy between Bloodtide and summoned minions. Investing in passive effects that increase long-term damage and reduce cooldowns will help maintain long-term damage output. Meanwhile, summoning Skeleton Mages or other minions can increase damage and repel enemies, allowing players to focus on positioning and survival.

The Abyss in Diablo IV is the ultimate test of a build's survivability and damage output. This build's strength lies in its high durability. Even under powerful enemy attacks, the damage-over-time effect remains unaffected, making it easier for players to survive and advance deeper into the Abyss. This is especially effective when paired with carefully selected Chaos uniques item that optimize both offense and defense.
