This Zodiac-style weapon drops in both of the Canthan Elite Missions.
Uninscribable versions are universal in the caster attribute type they can be linked to, and the damage type of these is determined by the respective attribute. These are dropped by the monsters and the chests in The Deep and Urgoz's Warren.
Inscribable versions can drop out of the end chest of The Deep or Urgoz's Warren. They can only be linked to the Primary attribute of its respective caster profession (except for Mesmer where they are tied to Inspiration Magic).
Dye affects the glowing gems on the staff. The staff is dyed yellow by default.
