The Sanctum Guardian is the first boss of the Temple of Aminishi elite dungeon. She is a large Crassian that guards the temple's sanctum to prevent both outsiders and unworthy acolytes from exploring the inner sections of the temple.

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

In Story mode her health is reduced by 50% and her damage output is reduced by 66%


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.
