Managing mana is crucial for this build, as Chthonic Fissure and Chaos Bolts can quickly deplete resources. The Soul Stealer node in the Warlock tree, combined with Devour the Damned in Last Epoch gold the Chaos Bolts specialization, helps replenish mana while actively casting. Additional nodes like Cauldron of Blood and Crimson Favors further improve damage output by increasing Bleed chance and scaling physical interactions with Rip Blood.

Important Stats And Gear

One of the best aspects of this Warlock leveling build is its gear independence. Unlike some other builds that rely heavily on unique items, this one functions smoothly with just basic stat priorities. While progressing through the campaign, look for items that enhance Damage Over Time and Elemental Damage Over Time, as these contribute the highest gains to overall DPS. Fire Damage, Necrotic Damage, and Spell Damage are also valuable.

For defensive stats, prioritize Ward per Second, Ward Decay Threshold, and resistances. Health and armor are secondary but still useful. Intelligence scales several key nodes and skills, so it would be taken whenever possible. Cast Speed and Mana Regeneration round out the list, improving both smoothness and efficiency.

Uniques To Watch For

Although no unique items are mandatory, several can improve the quality of life or reduce damage:

Advent of the Erased: Increases movement speed and pairs well with Fleeting Crone.

Blood of the Exile: Boosts bleed damage, movement speed, and grants Intelligence.

Calamity: Provides significant bonuses to Chthonic Fissure and Ignite damage.

Soulfire: Enhances Fire damage and Ignite chance, while boosting Armor when ignited.

If you acquire a Rune of Ascendance during leveling, use it on boots in hopes of obtaining Advent of the Erased or Blood of the Exile. Both dramatically increase campaign efficiency by speeding up movement, which quickly becomes more impactful than raw damage once enemies are dying within seconds.
