Malachai, The Nightmare (Act 4)

Master the Malachai, The Nightmare boss fight in Path of Exile Act 4. This guide provides strategies, stats, and tips to overcome this challenging encounter.

Stats / Weaknesses:

• Malachai is a large, imposing boss with significant health and damage output.
• He is resistant to most damage types but can be vulnerable to specific damage types depending on the phase.
• Focus on avoiding his area-of-effect attacks and managing the adds he summons.

Phases:

1. Phase 1: The Nightmare
   Malachai remains in his physical form, utilizing powerful melee attacks and summoning adds. He will also cast various spells, including a sweeping beam attack and a ground-based AoE. The arena will be filled with hazardous pools.
2. Phase 2: The Heart of the Nightmare
   After depleting his health in Phase 1, Malachai will merge with the Heart of the Nightmare. This phase introduces new mechanics, including a large, pulsating AoE that covers most of the arena and requires precise movement to avoid. He will also continue to summon adds and utilize powerful projectiles.

Strategy:

• Phase 1: Keep moving to avoid Malachai's attacks and the adds. Focus your damage on Malachai while kiting any summoned monsters. Utilize any defensive cooldowns you have for his more powerful attacks. Be mindful of the hazardous pools on the ground.
• Phase 2: The key to this phase is understanding the pulsating AoE. Stay on the edges of the arena and move inwards only when necessary to dodge. Prioritize killing the adds quickly as they can overwhelm you. Continue to focus damage on Malachai whenever there is an opening.
• General Tips: Ensure your build has adequate life regeneration or sustain to deal with the consistent damage. Bring flasks that can cleanse curses or remove bleed/poison effects. If you are struggling, consider respeccing into more defensive or offensive capabilities tailored to this fight.
