Shade of the Archmage

Purple Parlor
Meet the Image of Archmage Modera at the Violet Citadel and use the portal to the Purple Parlor. Defeat Shade of the Archmage and collect the Arcane Mote for Heart of Disruption. After turning it in, follow Friend of the Kirin Tor or Shrewd Negotiations to Archmage Celindra.
Shade of the Archmage
Bounding Mana threatens both its outward and return paths, while Mass Polymorph interrupts the fight before the Shade restores mana with Evocation.
Abilities

Arcane Bolt
Hurls a magical bolt at an enemy, inflicting Arcane damage.
Maintain healing on the tank for Arcane Bolt while the group moves around Bounding Mana.

Bounding Mana
Move out of the orb's outward path and leave its return path clear as well. Reposition the Shade away from the orb's origin.

Arcane Explosion
Sends out a blast wave of magic, inflicting Arcane damage to nearby enemies.
Move away from the Shade for Arcane Explosion after the orb returns; dodging the orb alone does not avoid this nearby blast.

Mass Polymorph
Transforms nearby enemies into an animal, forcing it to wander around for up to 8 seconds. While wandering, they cannot attack or cast spells.
As the Shade runs out of mana, prepare for a period in which Mass Polymorph prevents the group from attacking or casting.

Evocation
While channeling this spell, your mana regenerates at an accelerated rate.
The Shade restores mana with Evocation after Mass Polymorph. Once control returns, recover the group's positions and resume the fight.
Tank- Move the Shade away from Bounding Mana's launch position without crossing its return path. Create distance for the following Arcane Explosion, then restore control after Mass Polymorph ends.
Healer- Keep the tank covered for Arcane Bolt while moving clear of both orb paths. Recover the group's health as the Shade's mana empties, before Mass Polymorph stops your casts.
Damage- Dodge Bounding Mana on both legs of its journey and back away from the following Arcane Explosion. Resume damage after Mass Polymorph and Evocation rather than treating the mana refill as the end of the encounter.
