Fathom Lord Karathress

Fathom-Lord Karathress is the third boss you encounter in Coilfang Reservoir Wing 4.

## **Mechanics**

* Cataclysmic Bolt [Every 7 seconds] - Targets a random ranged hero, dealing damage and stunning for 1.5 seconds.

* Sear Nova [Every 11 seconds] - Karathress inflicts damage to nearby heroes around his position.

* Materialization [Every 15 seconds] - The phantoms temporarily become vulnerable to attack for a short duration before becoming invulnerable again.

* Dash [Every 20 seconds] - The boss places 2 embers on the floor in a random location in the boss room and charges between the the embers before moving to his starting position. He will charge to the red ember first and then travel to the green ember before returning back to his starting position.

* Frenzy [At 25% Health] - On a low health threshold Karathress falls into a rage, increasing his base attack and effectiveness of all his abilities by 45% for the remainder of the encounter. His Phantoms are also buffed if they are alive.

          *Karathress (Frenzy)*

* Enrage [300 seconds]

### Adds

* Phantoms - Karathress fights with 2 of his Phantoms. They will attack random heroes and repeat Karathress' abilities with 25% damage.

## **Tactics**

* The ranged damage dealers and healer should always stay near the bottom of the room below the two blue lanterns. The main tank should keep Karathress just above the lanterns to avoid unnecessary damage caused by Sear Nova from damaging the ranged raid members.

* The Off-tank should be prepared to grab the Phantom adds as soon as Materialization activates to bring them together for AoE damage.

* Keep an eye out for the embers that spawn when Dash activates, Karathress will always go to the red ember first so prioritize avoiding the red ember before the green ember.

* It is heavily recommended to kill the Phantoms before Karathress hits 25% health, because they will also become stronger when Frenzy is active.

* Save powerful abilities and Bloodlust for when Karathress hits 25% to end the fight as quickly as possible. During Frenzy, melee damage dealers should try to move out of range of Karathress before he uses Sear Nova because the damage received is devastating. He may also use Cataclysmic Bolt to drop a target low and finish them with Sear Nova in a combo if the timers line up.
