To ensure a smoother experience, it is advisable to out-level the first Capstone Dungeon before entering, considering that the enemies in that particular dungeon are fixed at level 50. Also, it is beneficial to come prepared with a specific build and an elixir for survivability.

Defeating The High Council

The High Council Boss Fight

The first boss fight in the Capstone Dungeon consists of four mini-bosses. Defeating them in any order will trigger enemy swarms. 

Here are some strategies I recommend for defeating the High Council:

  • Prioritizing the Sacred Physician boss is important to prevent revivals, and stun abilities can break the bosses’ stagger meter effectively.
  • Following the triumphant victory against the High Council, players will encounter the Curator, a formidable Lich boss known for its aggressive nature.
  • Crowd control abilities, damage resistance, and good preparation are recommended for the Curator boss fight.
  • Lightning Resistance and Undead-slaying elixirs are advised for boss fights in the Cathedral of Light.

Facing The Curator

The Curator Boss Fight

The final boss of the first Capstone Dungeon is The Curator. This boss poses a significant challenge with its devastating magical attacks. I’ve got a few tips that might prove to be useful for you:

  • Ensure you are adequately leveled.
  • Use the Elixir of Undead Slaying to increase damage against skeletons.
  • Unleash a barrage of attacks, including your ultimate, at the start of the battle.
  • In a party, divide tasks, with some members focusing on the boss and others dealing with the spawned skeletons.
  • Quick movement and speed are crucial in this fight, so incorporate these elements into your build.
  • Manage health potions carefully and upgrade healing abilities if possible.
  • When attacking, aim for the boss’s back to avoid its powerful scythe swipe.
  • Be cautious of bone walls and spinning winds, as they can impede your movement.

Subsequent Capstone Dungeons

After defeating The Curator, you unlock World Tier 3: Nightmare as it presents you with further challenges in subsequent Capstone Dungeons, such as the Fallen Temple and Archives of Issalia, each with its bosses and unique strategies to defeat them.

Overcoming Elias In The Fallen Temple

The final boss in the Fallen Temple Diablo 4 Capstone Dungeon is Elias, who utilizes long-range fire magic and summons mobs. Here’s how you can defeat Elias:

  • Prepare with items like Desert Escape Magic Incense and Strong Elixir of Fire Resistance.
  • Use an Iron Skin Elixir for extra armor and strategically dodge or use defensive skills to avoid high-damage abilities.
  • Understand Elias’s attack patterns and adapt accordingly. These include fire rings, orbs, fire waves, ritual circles, and a large triangle ritual.
  • Use class-specific strategies; for example, for Necromancers, using Undead Minions, Bone Spear, Corpse Tendrils, Army of the Dead, and defensive skills like Blood Mist are beneficial.

Therefore, surviving the Capstone Dungeons in Diablo 4 requires a combination of proper preparation, strategic gameplay, an understanding of boss mechanics, and efficient use of class abilities.
