Trials Boss Guide - Sunspire - Yolnahkriin

I highly recommend checking out Code's Mechanics Guide here for a written version: https://forums.elderscrollsonline.com...

Yolnahkriin can be broken down into a "grounded" phase and several "flying" phases. He will fly at 75, 50, and 25 percent health remaining.

Yolnahkriin "Grounded" moves

Flame Aura - There will be an aura under the dragon that damages anyone underneath him.

Wing Thrash - If you are too far to the left or right of the dragon (i.e. if you are by the wing), he will smack you with his wing. This will throw you back (assuming it doesn't kill you) and put you in a CC break immune stun for about 5 seconds.

Flame Breath - Giant conal AoE

Heavy Attack - Dodgeable, but will leave an AoE on the ground.

Light Attack - He bites when in melee range, and shoots an fireball at ranged. The fireball puts a debuff on you so flame damage moves does more damage. The bite move places a bleed on you.

Focused Fire - He will target one random person with the fewest stacks of Focus Fire. This will never target the tank that has taunt, and if you are far away from him, you will also not get targeted. There will be a large AoE that appears under the person's feet. The more people in the AoE, the less damage it deals to each person. However, each hit will place one stack of the Focus Fire debuff, which causes the next hit of Focused Fire to hit harder. You will need 2 stacks with 5 people to survive this move (1 healer and 4 DPS per stack). These stacks will be on the wing and the head.

Flame + Iron Atronachs - He will spawn in one Iron Atronach and two Flame Atronachs about every minutes or so. The Iron Atronach should be held in the back by the off-tank. The Flame Atronachs will drop a pool of lava when they die. On HM, after about 20 seconds, the Flame Atros will "enrage" and turn blue. They will then chase down one random person and self-destruct, causing massive AoE damage.

Yolnahkriin "Flying" Phase

Cataclysm - He will breath fire down on the arena, which instantly kills anyone in the center. This also removes all lava pools from the Flame Atros and makes the Iron Atros take significantly more damage, although it also enrages them. During this time, the DPS need to kill the Iron Atros before Yolnahkriin lands.

Nahviintaas's Hard Mode Mechanics

Time Stop - Nahviintaas will throw down Time Stops throughout the fight. These will deal some minor damage if you get caught in it when the spell completes and stun you. You can CC break out of the stun.
