- Phasing — The Celestial Protector exists in a state of flux, held together by the immense power of the Energy Vortex. When the Protector has over 25% remaining health and exists outside the bounds of the Energy Vortex, players inflict 90% less damage to it.
- Arcing Energy — The Celestial Protector inflicts 94,000[note 1] Arcane damage to two[note 2] random players and applies Closed Circuit to each target.
- Closed Circuit — After being hit by the Arcing Energy, the Closed Circuit reduces the healing received by the target by 50% for 20 sec.
- Stability Flux — Upon reaching 25% remaining health, the Celestial Protector begins to pulse energy and periodically inflicts 25,000[note 3] Arcane damage on all players.
- Total Annihilation — Celestial Protectors explode when near death, inflicting 200,000[note 4] Arcane damage to all players.
In Heroic Difficulty, Total Annihilation also applies Destabilizing Energies. In Heroic Difficulty, Total Annihilation will trigger Catastrophic Anomaly if it hits no targets.
- Destabilizing Energies — Exposure to Total Annihilation causes lasting negative effects, stuns the enemy and inflicts 45,000[note 5] Arcane damage every 2 seconds until the target is healed to 80% of max health.
- Destabilized — When struck by Total Annihilation, powerful waves of energy course through the victim, rendering them more susceptible to the harmful effects of Total Annihilation. Players instantly die if Total Annihilation inflicts additional damage to them. Lasts for 2 minutes.
