Tectus – 1st Boss in “The Arcane Sanctum” (optional)


An ancient embodiment of the chaotic forces that shaped the terrain of Draenor, Tectus has been twisted and enslaved by the maddened Pale Orcs – who themselves barely maintain in control over this imposing force of nature.

Healing Strategy

This fight that start somewhat orderly, then rapidly deteriorates into absolute chaos. It is a fun fight for healers, since the chaos adds an extra layer of challenge.

Tectus most characteristic ability is that when he dies, he splits into two replicas of himself that inherent the exact same abilities he normally has. He goes from Tectus, the Living Mountain into 2 Shards of the Mountain. You are fighting Tectus times two, just with a little less HP. It won’t stop there though! If you kill the Shards, the Shards will then split into 4 Motes of the Mountain. If you kill both of the Shards at the same time, that means you have 8 Motes active, doing Tectus abilities times 8. Once the Motes die however, he is completely and irrevocably dead.

Now, let’s deal with the abilities that Tectus does. His first ability is Accretion. This is a constant ability that make him deal 5% more damage per stack. The only way to remove the Accretion stacks is to hit him. Sounds easy? Remember that the same goes for the all Motes of the Mountain, meaning someone should always hit Tectus or Tectus-remnants that are active.

Tectus - Earthen Pillar indicator
Earthen Pillar indicator

The second ability is Earthen Pillar. This is a large earthen spike that erupts from the ground. It is an instant kill-shot and should always be avoided. It has a very large indicator to show where the pillar will erupt, which makes it easy to avoid. The problem is that the pillar creates an obstacle for line of sight. It takes a long time for these pillars to despawn, which makes it paramount to place them properly. Since Earthen Pillar always target ranged players, ranged should stack close to the wall and slowly rotate around the room, only moving when targeted by Earthen Pillar.

Tectus - Crystalline Barrage
Crystalline Barrage

Crystalline Barrage is another quite worrisome ability. It is a red mist which starts at the boss and then fixates on a random player which it pursues, leaving trails of Crystalline Barrage behind. It always fixates on a ranged player which means that if the fixated player doesn’t move, you’ll have mist in your stacked ranged group, causing immense damage. When a player gets fixated, it should run towards the opposite direction of where everyone else is and kite the red mist away. The easiest tactic is that the ranged group run left to avoid Earthen Pillar and the fixated person run right with the red mist.

Tectus will also create mini earthen pillars, called Fracture. These will not instantly kill you if hit, but it will do high amount of damage. He will do this ability more frequently than Earthen Pillar, so the raid has to be on its toes.

Now for the most important ability Tectus does: Tectonic Upheaval. This ability do high, unavoidable damage to the entire raid. You will have to save your healing cooldowns for this ability, since the damage spikes over a longer period of time. The important part of this ability is that Tectus can only be killed or split into shards/motes during this ability! DPS should save their cooldowns for Upheaval and burst him down, because they won’t be able to kill him otherwise. If DPS fail, the raid has to wait for the next upheaval which will prolong the fight immensely.

All Shards and Motes of the mountain have these abilities, meaning you could have theoretically 8 Tectonic Upheavals at the same time. This is why DPS should time the kills as best as possible. The easiest is to burst down one of the Shards and then deal with 4 Motes. Leave the other Shard until the Motes are dead, then go on the second Shard and the last 4 Motes.

Tectus will also summon adds that have some important abilities. There are the Night-Twisted Berserkers, which enrage and forget their current target and will start hitting people in the raid. These should be cleaved down, and when they reset the aggro table, tanks should re-taunt them. There are also the Night-Twisted Earthwarper. Earthwarpers do a frontal cone which should naturally not be directed towards the raid, but they should be standing close to the melee and be cleaved down.

The most dangerous ability Earthwarpers do are Gift of Earth. Gift of Earth is a vortex that travel towards Tectus, and if it reaches him he will gain stacks of Accretion. It can be intercepted by having a player running through it, but it causes high damage and a debuff called Petrification. If a player is hit by Tectus melee attacks while having this debuff active, Tectus will gain stacks of Accretion and be healed. It is also possible to interrupt this ability, which will also cause high damage. There are therefor some options on how to handle it:

  • Let the vortex reach Tectus; causing him to gain stacks of Accretion.
  • Having the off-tank intercept it, which will cause high damage and the off-tank can’t be hit by Tectus with the Petrification debuff active (otherwise Tectus will gain stacks of Accretion and will be healed).
  • Interrupt Gift of Earth cast, causing high damage.

During this fight, tanks will take immense damage. The danger is that tanks stand too far away from healers, since they will run around and pick up adds while healers are stationary in the ranged group. Tanks should be really alert to where the healers are standing.

Melee DPS who are not aware of where ranged are standing will most likely take a hit from Crystalline Barrage, which spawns on the boss and travel towards a fixated ranged player. Other players who are not paying attention could take spikey damage from both Crystalline Barrage and Fracture. Players who stand in Earthen Pillar will die instantly.

For healers it is a fairly simple fight until the Motes are up. Then the raid will spread more and it will be every man for himself. During this part of the fight, healers have to watch out for all of Tectus attacks while trying to reach players in need. During Tectonic Upheaval, healers should rotate the big healing cooldowns. Just don’t use Revival too soon in the channel, since it’ll be more incoming damage until Tectonic Upheaval is done.
