The Purifier Boss Guide


The Purifier is - next to the Constrictor, the Enslaver and the Eradicator - one of the four Guardians of the Elder. In order to fight him, you have to open a Purifier occupied Map. These Elder Influenced Maps have a special Boss Icon in place of the typical Map Icon. Defeating an Elder Guardian for the first time unlocks a favourite Map slot for your Atlas.

Each of the Elder Guardians drop a specific Map Fragment that is required to face the Elder. The Elder and the Shaper drop different map fragments that are needed to open portals to the Uber Elder Encounter. Defeating the Uber Elder for the first time rewards you a Decayed Voidstone that can be socketed into the Atlas.

The Elder - Boss Guide:

Elder Guardian Maps can be dropped upon killing any regular T14+ Map Boss on the Atlas and have 2 implicit modifiers:

Area is influenced by The Elder
Map is occupied by The Purifier

Area is influenced by the Elder
This implicit modifier adds the Elder influence to the Map, adding Elder monster packs

Map is occupied by The Purifier
This implicit modifier adds the Purifier as the new map boss, replacing the default boss of the area.

You can increase the drop rate of these Maps with the Atlas Passive skill Remnants of the Past. You can also obtain Elder Guardian Maps from Kirac or encounter an Elder Guardian as part of his Atlas missions. These Maps can also be acquired by getting Map rewards in other League Mechanics such as Tujen from Expedition, Delirium or the Ritual Altar.

An Elder Guardian Map can be converted into another Map via an Orb of Horizon and even upgraded in Tier with a Harbinger's Orb. However, you cannot change the Guardian that is occupying the Map itself.

Defeating an Elder Guardian counts as clearing the Map in terms of Master Missions and unlocking them for your Atlas. Note that Maps that are occupied by an Elder Guardian do not grant the Map completion bonus, since the Elder Guardian replaces the default Map boss.

It is possible to have multiple influences on a single Map. As an example, while in an Elder influenced Map, you can also encounter any of the Conqueror's of the Atlas invading it. This makes your Map more rewarding, but also increases the difficulty.

Loot Table

In addition to regular loot, the Purifier has the following boss-specific drops:

  • Fragment of Purification (100%)

Skills Breakdown

Default Attack

The Purifier strikes with his scepters at close range, dealing Physical Damage.

Double Slam

The Purifier performs a massive slam attack with both weapons, dealing heavy Physical Damage.


The Purifier calls down a flurry of weapons targeting you multiple times throughout its duration.

Sceptre Toss

The Purifier goes airborne, tossing his weapons, which deal heavy amounts of damage in an area on impact.
This ability hits hard and should be avoided.

Energy Blast

The Purifier charges up an energy blast snap shotted on to your location, exploding after a short period of time.
Make sure to immediately move out of the circle.

Animated Weapons

The Purifier fires a wave of projectiles that transform into Animated Weapons that chase you down.
Kill them to restore some Flask Charges.

Crossed Swords

The Purifier summons seven tentacled swords which surround you. Each tentacle fires a projectile crossing the center of the circle. Make sure to move after you see the tentacles spawning.

Boss Mechanics

Once you encounter the default Map boss in an occupied Map, the Elder appears to dispose of it and open a portal to the Guardian's domain. Make your way through the portal and find the Guardian locked in a Cocoon. The Elder starts summoning the Guardian, which is vulnerable as soon as the ritual finishes.

Make sure to check out the Skills Breakdown above to learn more about each of the abilities.

The Purifier can spawn in one of three different zones:

  • Vaults of Insanity
  • Halls of Delirium
  • Pits of Sorrow

At 66% and 33% health respectively, the Elder appears to teleport both you and his Guardian into another phase with new hazards to be dealt with.

Vaults of Insanity

Phase 1 - Beams of light travel through the area, dealing Fire damage over time.
Phase 2 - An altar is placed at the center of the arena, shooting Scorching Rays in two different directions.
Phase 3 - Yellow circles on the edge fire Spark projectiles that travel through the arena.

Halls of Delirium

Phase 1 - 4 burning orbs are placed on the edge of the arena, periodically firing circular explosions.
Phase 2 - Multiple fire beams travel through the arena in a straight line, dealing Fire damage over time.
Phase 3 - Two circular degen grounds chasing you, dealing Fire damage over time.

Pits of Sorrow

Phase 1 - Circular explosions appear periodically in random areas of the arena.
Phase 2 - Burning orbs drop from mid-air on random areas.
Phase 3 - Beams of light spawn that are chasing you, dealing Fire damage over time.

Map Modifiers

Since the Elder influenced Guardian Map is a typical Map, it can be modified with Currency like any other Map. But be careful! Some Map modifiers can make it very difficult.
