Elemental Mage

Elemental Mages are monsters that appear in the Rift.

Behavior
Depending on how close the player is to the Elemental Mage it will either attack with a short ranged or a long ranged spell of their current element.

Abilities
The Elemental Mages are able to switch between fire, electric and ice masks, granting them the respective resistances and allowing them to attack with different spells.

Their spell repertoire consists of a frost nova spell, an iceball spell, an eleclance spell, a lightning bolt spell that phases through walls, a short ranged fire particle spell and a fireball spell.

Tactics
Generally, there is enough downtime between their attacks and during their charge animations to easily dispose of them.
