Terros Heroic Boss Guide

Terros will target a random player and launch a swirling vortex, inflicting 961,298 Nature damage split evenly among players within 12 yards and causing eruptions of Awakened Earth.

Afterward, an Aftershock occurs at the impact location. 

This is a simple soak to split damage ability with an added twist. It triggers 2 other abilities at the same time which prevent you from assigning specific people to deal with it, and it also makes positioning a bit more complicated. You can also immune this but make sure to call it fast.

The Aftershock of Rock Blast inflicts 115,356 Nature damage to players standing in it, knocking them upwards.

It will create a puddle of earth (Stone-Legion Generals eruption) instantly after soaking the initial hit from Rock Blast. A few seconds later it will explode. The best way to deal with this is to have people soaking Rock Blast stand on the edge of the soak-circle. That way they only have to move 2-3 yards to dodge the puddle.

The earth erupts beneath several players, inflicting 27,637 Nature Damage to players within 2 yards and knocking them back. Upon erupting, the Earth Pillars will inflict 7,210 Nature damage to all players every 2 sec until destroyed. Upon destruction, it triggers a Seismic Assault.

Players are marked with a Yellow arrow and will have a small circle around them, you should make sure to place the Pillars in a line, or very close together. Do not stack with other players.

This ability comes pretty much at the same time as Rock Blast, which forces players targeted by Awakened Earth to skip soaking Rock Blast and deal with placing Awakened Earth in a proper spot.

Never place this in melee!

Inflicts 24,032 Nature damage to all players when an Earth Pillar is destroyed. Inflicts an additional 2,403 Nature damage every 1 sec for 10 sec. This stacks.

The important thing to understand here is that each Earth Pillar will give you a DoT. Meaning if you have 4 Pillars up, you will take 7,210 x 4 Nature damage every 2 seconds. If those pillars get destroyed, you will receive a different DoT (from Seismic Assault tooltip). However if you happen to destroy several Pillars, but miss some.. You will have two different dots hitting you at the same time. This is the worst case scenario and it will hurt the most, since not only will you take extra damage from two different dots, you will also eventually destroy all Pillars with Resonating Annihilation and trigger a much stronger Seismic Assault.

Terros discharges a line of tectonic energy (laser beam) that inflicts 242,728 Physical damage to players hit and increases damage taken by 30% for 45 sec. This stacks.

It will also destroy any Awakened Earth (Earth Pillars) caught in the blast. You should probably tank swap every Concussive Slam.

Basically the same laser from Halondrus which you now use to destroy Earthen Pillars. If done correctly, the Tank should never have to move with it. We will discuss more about it in the Strategy section.

Terros fractures the earth, inflicting 252,341 Nature damage to players within 12 yards of the impact location, and knocking them upwards. This will also trigger Fractured Rubble.

On testing, this ability would mostly target the largest clump of players which is 90% of the time the melee camp. Ranged are often split due to puddles on the ground and because they are dropping off Awakened Earth. So this ability mainly exists to keep melee players awake (he he).

It’s a large yellow circle, just move out of it.

When Terros reaches 100 energy, he will unleash a brutal slam a la Sire Denathrius (aka Pizza Slice). This slam inflicts 478, 246 Nature damage to all players caught in it, and destroys Awakened Earth Pillars. It will also trigger Fractured Rubble.

Rubble falls from the ceiling, inflicting 96,250 Nature damage to players within 6 yards of the impact location and leaving behind Resonant Aftermath.

Swirls will spawn on the ground that need to be dodged. It leaves a puddle behind, just don’t stand in it.

Both Frenzied Devastation and Tectonic Barrage abilities serve as a soft enrage and do not require special attention. 

One will trigger if you manage to fill the entire room with Resonant Aftermath (puddles) and the other will trigger if no player is in boss range. Both will deal massive damage and most likely cause a raid wipe.
