Encounter phases
Adventure Guide says
- Stage One: You Dare Invade? At the start of the encounter, Feludius and Ignacious enter the battle. Arion and Terrastra then watch from the balconies above. In Heroic Difficulty Arion and Terrastra assist their fellow councillors.
- Feludius Ascendant Councillor of Water
- Ignacious Ascendant Councillor of Flame
- Arion
- Terrastra
- Stage Two: We Will Handle Them! Once either Feludius or Ignacious reaches 25% health, both Councillors retreat. Arion and Terrastra then descend from above to carry on the fight.
- Arion Ascendant Councillor of Air
- Terrastra Ascendant Councillor of Earth
- Feludius
- Ignacious
- Stage Three: BEHOLD YOUR DOOM! Once either Arion or Terrastra reaches 25% health, the Councillors grow impatient and place all combatants in a stasis field. All four Councillors combine to form the Elementium Monstrosity, beginning the final phase of the encounter.
- Elementium Monstrosity The initial health of the Elementium Monstrosity equals the combined remaining health of each of the four Councillors.

Boss abilities
| Ability | Adventure Guide | Notes |
|---|---|---|
| Glaciate | Feludius unleashes a burst of Frost that damages all players in the room. Damage taken decreases with distance from Feludius, and any victims at point-blank range suffer fatal damage. Players afflicted by Waterlogged when Feludius uses Glaciate become Frozen and suffer additional damage. | lethal |
| Hydro Lance | ||
| Water Bomb | Water Bomb afflicts Waterlogged on any enemy damaged. | |
| Heart of Ice | ||
| Aegis of Flame | He begins channeling Rising Flames immediately after Aegis. | |
| Inferno Rush | Ignacious then rushes back to his last target, leaving a trail of fire in his wake. | |
| Flame Torrent | ||
| Burning Blood | ||
| Static Overload | Powerful gravitational fields cause this energy to dissipate harmlessly. | |
| Gravity Core | ||
| Call Winds | Arion focuses and agitates the nearby air into a violent cyclone. This cyclone wanders randomly around the room for 50 sec before dissipating. The cyclones knock upwards any player who touches them and inflict the Swirling Winds effect on that player. | |
| Thundershock | Players with the Grounded effect take greatly reduced damage. | |
| Lightning Rod | Arion marks a random player as a target for a forthcoming Chain Lightning attack. In 25 player raids Arion marks three random players as targets. | |
| Disperse | Arion dissolves into swirling wind and materializes elsewhere in the room, then casts Lightning Blast. | |
| Gravity Well | Terrastra creates a pocket of intense gravity near a random player. Players pulled into Gravity Wells gain the Grounded effect. | |
| Harden Skin | If Terrastra reaches this threshold before the effect ends, Terrastra's rocky skin shatters, causing him to suffer all the damage that Harden Skin absorbed. | |
| Quake | Players with the Swirliing Winds effect take no damage. | |
| Eruption | Terrastra causes rocky spikes to emerge from the ground around his feet. | |
| Frozen Orb | Feludius summons a sphere of pure Frost energy to relentlessly pursue a random player. The sphere gains speed over time. | |
| Flame Strike | Ignacious targets the location of a random player, then launches a massive fireball towards that location. | |
| Electric Instability | The electrical bolt chains to nearby players. The Elementium Monstrosity is an unstable creature and emanates increasing amounts of electrical energy over time. The increased energy causes the electrical bolts to strike an increasing number of targets. | |
| Gravity Crush | When the effect ends, the player falls to the ground. In 25 player raids the Elementium Monstrosity traps three players in a gravity bubble. | |
| Lava Seed | The Elementium Monstrosity showers the surrounding area with kernels of pure Flame energy. | |
| Cryogenic Aura | The Monstrosity continually forms pools of Liquid Ice beneath its feet. Pools of Liquid Ice expand while they remain in contact with the Monstrosity. |
