Duriel, King of Maggots

Summoning Requirements & Location

In order to summon Duriel, collect 2 Mucus-Slick Eggs (from Varshan in World tier 4). Then collect 2 Shards of Agony (from Grigoire in World Tier 4). Again, only the player that summoned Varshan & Grigoire receives these items!

Once you have these you can travel to Gea Kul, and head east to the Gaping Crevasse where you can summon Duriel to fight.

Before heading to the fight, drop by the Alchemist to pick up a Potent Elixir of Poison Resistance to help counter his Poison abilities.

Duriel is located in the Gaping Crevasse to the East of Gea Kul

Health Bar & Stagger

One example of a Boss health bar.

Each Boss's health bar has multiple breakpoints. Once a breakpoint is reached, the red arrow flips up and turn grey. This indicates that you are in the next phase of the fight, while also dropping multiple healing vials. Each phase is more challenging than the last.

Stagger Bar Mechanic

Immediately beneath the health bar is a stagger bar, this slowly fills when Crowd Control (CC) is dealt. Once full, the Boss is rendered helpless for a short window of time. Use this opportunity to unleash as much hell as you possibly can.

Boss Mechanics and Strategy

Pay attention to each of the attacks used by Duriel, King of Maggots, the following section guides you through the boss's most dangerous abilities.

Duriel, King of Maggots awaits you in his domain.

Duriel's Abilities

Initially 2 Pangs of Duriel attack you. After a few moments, Duriel himself appears and the fight begins.

  • Poison Strike - When Duriel attacks with his claw, he inflicts Poison on hit.
    • This is difficult to avoid, but doesn't hit very hard.
    • Evade or use a movement skill to move behind the boss.
  • Poison Slam - Duriel slams his claw into the ground creating a Poison pool, and causing several poisonous projectiles to splash out in a circle.
    • Move away from the impact point for the initial telegraph, but stay at close to medium range.
    • This way you avoid the projectiles, and the pools they spawn.
  • Expel Waste - The boss inhales then after a short delay, Duriel expels waste from his lower maw.
    • Move away from the boss so you can dodge between the projectiles.
  • Rain of Maggots - At 80% and lower Duriel raises his claws causing maggots to rain from the ceiling.
    • Use AoE damage skills to clean up the maggots as you continue the fight.
  • Rampaging Charge - Below 80% health Duriel charges wildly flailing both of his claws in the process. Players caught at the end of the charge take significant damage.
    • This is a dangerous mechanic, so treat it with care.
    • When he begins his charge, move away from the boss.
    • If you're playing a melee build, wait for the move to finish before going in to attack.
  • Claw Spike - As his health gets lower, Duriel begins using a move similar to Poison Slam, except it hits harder and doesn't spawn any pools.
    • Watch for the telegraph where he raises his claw, and move away from the boss to avoid the impact.

Pang of Duriel

Throughout the fight, Duriel buries himself into the floor, summoning Pangs of Duriel. These minions are dangerous if ignored so killing them is your top priority.

  • Pangs of Duriel - 2 of these minions emerge in the room at the beginning of the encounter, approach and attack them to get Duriel to appear.
    • At 60% health 1 Pang of Duriel is summoned.
    • Then, at 40% and 20% health 2 Pangs of Duriel are summoned.
    • While below 20% health Duriel occasionally re-uses this ability.
  • Poison Nova - the Pang of Duriel occasionally spits out a nova of poisonous projectiles.
    • Avoid the projectiles by moving close to the minions.
  • Dive - After being approached, the Pang of Duriel dives into the ground in an attempt to escape.
    • Wait for it to reappear, then continue dealing damage.

Tormented Version

As part of the Boss Ladder system, this boss has a Tormented level 200 version that is much harder but more rewarding. In addition, certain abilities add a stacking extra damage taken debuff that only allows a few mistakes throughout the fight before the incoming damage overwhelms you. These abilities are:

  • Poison Slam (Ground Circle)
  • Expel Waste (Projectiles)

Tormented Bosses require x3 the amount of materials and x2 Stygian Stones acquired from high level Pit clears to summon and drop x5 the amount of loot. For endgame farming of Uber Uniques, it's advised to spec into a proper Bossing setup to complete these.
