The Sanctum Guardian is the first boss of the Temple of Aminishi elite dungeon. She is a Crassian that guards the inner sections of the temple.

Players may use a fishy treat to skip the fight with the Sanctum Guardian.


The Sanctum Guardian attacks with AoE ranged and melee attacks. Her ranged attack consists of a purple ball landing on its target's position, and can be avoided by moving out of the way. The melee attack is a splash of water which hits all players within a 5x5 radius of the Guardian.

After the initial 4 ranged attacks, she splashes the surrounding area with a large blast of water, and from there onward, every ranged attack is followed by the special attacks rotation.

For her second attack, the Guardian blasts a torrent of water from her mouth, which is always aimed starting at the north side of the room and turns in a counter-clockwise formation, dealing up to 7,000 soft typeless damage if the player is hit by it. Players can Surge through the water or Resonance it for no damage. It cannot be outrun, as the Guardian moves too fast to do so. Players can safely avoid the attack by standing in the north-east corner, then run north-west.

Her third attack consists of picking one player and blasting a jet of water on them, causing a blue bar beneath their adrenaline bar to appear. When this bar fills, the 5x5 area around where the player stood is enveloped in purple flames. While this initially deals low damage, it will quickly cap out at 5,000 damage per tick which will easily kill any player standing in it. This attack pattern repeats until the fight is over.

After every three torrent attacks, she will summon two crassian reinforcements to assist her in battle.

Using a Fishy treat on the GuardianEdit

  • A fishy treat? It may pass!


In normal mode 2 drops are rolled; the 100% drop and a common mob drop.
In story mode Crassian Allegiance is the only drop; however its drop rate is higher compared to normal mode.[1]


The Guardian drops onyx dust, unless a fishy treat or Crassian Allegiance is dropped, which replaces the dust.
