Boss farming

Kessime's Legacy can drop from Lord Zir and other Ladder/Uber Bosses. These high-tier bosses are one of the most reliable methods for farming this unique item.

Running Nightmare Dungeons is another effective way to obtain Kessime's Legacy, as they frequently reward unique items. Since these dungeons provide high-tier loot, focusing on high-difficulty Nightmare Dungeons is one of the best ways to farm for this item.

Helltide Events

Kessime's Legacy can also drop from Helltide Chests, making Helltide farming an effective strategy.

What is the unique effect of Kessime's Legacy in Diablo 4?

In Diablo 4, Kessime's Legacy drastically enhances the Blood Wave skill by modifying its mechanics. Instead of a single wave, Blood Wave now generates two waves—one on each side of the Necromancer. These waves move toward the player, pulling in surrounding enemies before converging at their feet and exploding for massive damage. This effect significantly improves Blood Wave’s crowd control potential.

Additionally, enemies struck by Blood Wave take 5-10% increased damage from subsequent Blood Waves, with this effect stacking up to 150-300%. Thus, repeated uses of Blood Wave will deal exponentially more damage to enemies caught in its radius. When combined with cooldown reduction and double-damage chances from the item's affixes, Kessime’s Legacy allows for highly effective chain damage.
