Heroic Overview

Tectus is the third boss in the Highmaul raid instance. There are a lot of interesting mechanics to this encounter and how we plan to overcome these challenges I will detail in our strategy section below but for now lets go over the basics of this fight. This is a one stage encounter that takes place in the Market District of Highmaul. When the battle begins Tectus will be fully formed and buffed with a spell called The Living Mountain. While under the effects of this buff Tectus will be unkillable and will periodically gain energy (the rate of gain increasing as he loses health). Upon reaching 100 energy he will start channeling an ability called Tectonic Upheaval during which he will temporarily lose The Living Mountain buff and become vulnerable to shattering. The first time Tectus is shattered he will split into two Shards of Tectus, when each of these Shards are shattered they will split into four Motes of Tectus. Both Shards of Tectus, and Motes of Tectus have all the same abilities as the fully formed Tectus. It is important to mention that Motes of Tectus can be killed outright whether or not they are channeling Tectonic Upheaval. Players are victorious over Tectus after they have killed all of the Motes of Tectus. Lets start by reviewing Tectus' abilities.

  • Accretion is a buff that Tectus will periodically gain that increases his damage inflicted by 5%. This effect stacks. Damaging Tectus removes stacks of Accretion.
  • Earthen Pillar is an ability where Tectus will erupt a massive pillar from the ground at a targeted location killing any players still standing on it (25 energy). This abilites area of effect is telegraphed and therefore completely avoidable if players are quick to move out of the way.
  • Crystalline Barrage creates a cloud of crystalline blades that moves towards a targeted player. Players who enter the cloud of crystalline blades suffer large Physical damage each second they remain in the cloud.
  • Fracture causes a spike of earth to shoot up from the ground, inflicting a large amount of Physical damage to players standing where the spike erupts knocking these players back. This abilites area of effect is telegraphed and therefore completely avoidable if players are quick to move out of the way.
  • Tectonic Upheaval is an ability that Tectus will start channeling upon reaching 100 energy. While channeling he will create a massive series of earthquakes that each inflict a large amount of Physical damage to the entire raid. If Tectus's health is depleted during Tectonic Upheaval, he will Shatter. Remember as previously mentioned Motes of Tectus can be killed outright whether or not they are channeling Tectonic Upheaval.
  • Hollowed Heart of the Mountain, after being shattered Tectus will split by a factor of 2 (first split is 2 Shards of Tectus, second split is 4 Motes of Tectus) with each product having a fraction of its predecessor's health. These smaller versions do not gain additional energy as their health percentage decreases however the rate of energy gained will increase in relation to their proximity to one another.

At the beginning of the fight, only while Tectus is fully formed, there will be two types of adds that spawn Night-Twisted Earthwarpers and Night-Twisted Berserkers. These adds will attempt to empower Tectus and attack players and must be dispatched as quickly as possible. These adds have the following abilities.

Night-Twisted Earthwarpers

  • Gift of Earth creates a swirling vortex of earth in an attempt to empower Tectus. If the vortex reaches Tectus, he will gain 10 stacks of Accretion. Players may intercept the vortex and if they do, they suffer a large amount of Physical damage and are afflicted with Petrification.
  • Petrification is a debuff placed on players that have been hit by the Gift of Earth. A petrified players movement speed is reduced by 2%, and Tectus will absorb their petrification whenever he makes a melee attack against them, granting him stacks of Accretion and healing him. This means Tectus' tank cannot soak Gift of Earth.
  • is an ability that inflicts a large amount of Nature damage to all enemies within a cone in front of the caster.

Night-Twisted Berserkers

  • Raving Assault, the Berserker is afflicted with temporary insanity, forgetting their current target, clearing all threat, and dashing towards a random player. The Berserker inflicts moderate Physical damage to targets caught in the path of the dash.

What makes this encounter challenging isn't Tectus and his few abilities, its when there is multiple copies of Tectus (potentially up to 8) with those same abilities. In order to be successful at this encounter everyone needs to exercise strong raid awareness and good positioning. That means players should always avoid being hit by Earthen Pillar, Fracture, and Earthen Flechettes. Players targeted with Crystalline Barrage will need to react quickly and move out of the raid in a safe direction. Gift of Earth should always be soaked by the off-tank or anyone with a strong damage mitigation ability. Players who afflicted by Raving Assault need to use damage reduction abilities when appropriate.

Mythic Changes

On Mythic Tectus gains one new ability all of the other previous abilities from Heroic remain intact however some of them have been slightly modified to make the encounter more challenging. Lets begin our Mythic review by looking at Tectus' new ability Hollowed Heart of the Mountain.

  • Hollowed Heart of the Mountain will cause Tectus and Shards of Tectus to resurrect after they have been shattered with 20% of their health. When respawned they will retain all their former abilities but now can be killed independent of Tectonic Upheaval. Both Tectus and Shards of Tectus will contribute to the Accretion gained to nearby enemies, so it is important that they are dispatched quickly.

In addition, Night-Twisted Earthwarpers and Night-Twisted Berserkers will continue to spawn throughout the encounter in contrast to Heroic where they only spawned during the initial stage while Tectus was alive. The approach to tanking these adds remains the same as Heroic, face the Night-Twisted Earthwarpers in a safe direction away from the raid so players don't get annihilated by Earthen Flechettes. Position Night-Twisted Berserkers on top of the boss(es) so they can be cleaved down.

On Mythic Gift of Earth does a significant amount of damage so above all Dps must prioritize Earthwarpers. Since they can be stunned, Dps will need to kill them inside a stun to prevent them from casting this ability. Lastly on Mythic Earthen Pillars no longer disappear, they will persist throughout the entire encounter so placing Pillars intelligently to conserve space is a requirement to defeat this boss.

Going Ham

We will use Heroism/Time Warp after the first shatter when the Shards of Tectus reach approximately 75% energy. We want to use it here because the sequence of Tectonic Upheaval is a critical juncture in the encounter where the raid will be taking the largest amount of damage so its important that we exit this stage quickly and with both Shards shattered.

Strategy

On the pull, Range will be stacked up to the right of the entrance on the outer perimeter. Tanks will position Tectus approximately 30-yards away from Range on the same edge facing him at a 90 degree angle in respect to where the Range group is positioned. Remember this is to allow melee to have his backside without being affected by Crystalline Barrage. Players targeted with Crystalline Barrage will move forward a bit then strafe left on an imaginary inner track. The goal for players with Barrage is to stack the clouds as much as possible to minimize its footprint, as an analogy think of it as multiple lanes on a running track, when a player is targeted they move forward into a clear lane and run clockwise (left) to kite the cloud.

Flamethrower Positions

In Mythic we will be shattering both Shards of Tectus at the same time. The goal is to keep both Shards relatively at the same health percentages because the amount of energy generated per second is dependant upon how much health they have remaining. We don't want to stagger two Tectonic Upheavals because we simply don't have the cooldowns to survive that amount of raid wide damage over that additional extended period of time. Theoretically this will be the point where the raid will be taking the highest amount of damage. Healers will need to expend their raid cooldowns, players need to use any personal damage mitigation abilities and health tonics to survive. We will use Heroism/Time Warp just before entering this phase and Dps will need to use their second potion here. If Dps fails to shatter both Shards during this Tectonic Upheaval it will most likely result in a raid wipe.

The after the both Shards have been shattered, things are going to get chaotic. Kill the respawned Shards first, but remember cleave is the name of the game. At the start we will get ten Crystalline Barrages, (yes ten) kite them (still strafing left) along the outer edge of what remaining space we have. Range spread out continue to stand on the outer edge of the room so we can spawn Earthen Pillars away from melee and where they are not a line of sight obstruction for healers. While all this is going on Dps will still need to stun and focus down Night-Twisted Earthwarpers as they spawn.

  • At the start position Tectus on the right edge of the courtyard facing him at a 90 degree angle, approximately 30-yards away from the Range. As the Range group transverse the circumference of the room depositing Earthen Pillars make sure along with them so you never out range your healers.
  • The tank currently not tanking Tectus will need to pick up any Night-Twisted Earthwarpers and Night-Twisted Berserkers that spawn and position them on top of the boss(es). With Night-Twisted Earthshapers make sure to face them away from other players to minimize damage from Earthen Flechettes.
  • When Tectus is shattered, each tank will grab a Shard of Tectus and one tank will need to grab the reanimated Tectus. Position all the bosses and adds on top of one another so Dps can maximize their efforts.
  • During the final shatter that produces Motes of Tectus, gather up the eight Motes and the two Shards and stack them on top of one another as quickly as possible. Expect to get annihilated here so utilize all cooldowns both internal and external to stay alive as long as possible.
  • Be mindful that all players will take heavy damage during Tectonic Upheaval. The second sequence of Upheaval will be the most demanding part of the fight so plan accordingly.
  • Make sure to move out of both Fracture and Earthen Pillar! Both these abilities are telegraphed and therefore completely avoidable if players are quick to move out of the way.
  • Remember if you are targeted with Crystalline Barrage that you are to move inward from the Range and then proceed strafe left kiting the cloud. If you are uncertain about this please refer to the strategy diagram or ask myself for further explanation.

Dps needs to adhere to the following target priority based upon whether or not the boss(es) are casting Tectonic Upheaval.

  1. Night-Twisted Earthwarpers
  2. Tectus
else if Tectus IS casting Tectonic Upheaval
  1. Tectus
If Shards of Tectus are NOT casting Tectonic Upheaval
  1. Night-Twisted Earthwarpers

  • Make sure to move out of both Fracture and Earthen Pillar! Both these abilities are telegraphed and therefore completely avoidable if players are quick to move out of the way.
  • Do not stand in front of Night-Twisted Earthwarpers they have a frontal cone attack called Earthen Flechettes that deals a significant amount of damage to all players hit by it.
  • Remember if you are targeted with Crystalline Barrage that you are to move inward from the Range and then proceed strafe left kiting the cloud. If you are uncertain about this please refer to the strategy diagram or ask myself for further explanation.
