• Evolution
• Aura of Acceleration
• Dark Command
• Evolved Twilight Zealot
• Force Blast
• Gravity Strike
• Grievous Whirl
• Shadow Strike

Corla, Herald of Twilight will start the fight with 3Twilight Zealots worshiping her. Corla will channel beams of energyinto these Twilight Zealots, giving them stacks of Evolution every second. Upon reaching 100 stacks of Evolution, the Twilight Zealots will transform into anEvolved Twilight Zealot, gaining multiple deadly abilities. Toprevent this from happening, a player will need to be assigned to each beam to"interrupt" it, by standing between Corla, Herald of Twilightand the Twilight Zealot. This will instead cause the player to gainstacks of Evolution, rather than the Twilight Zealot.If a player reaches 100 stacks of Evolution, they will insteadtransform into a Twilight Drakonid, attacking their allies. Toprevent this, stand in the beam until you have around 80 stacks of Evolution, then move out until your debuff resets.Corla, Herald of Twilight herself is rather weak, with her main threatbeing Dark Command, as this can fear a target away from theirbeam and prevent them from soaking the stacks.

• Quicksilver Armor
• Superheated Quicksilver Armor
• Heat Wave
• Burning Metal
• Cleave
• Lava Spout

Karsh Steelbender starts the fight with Quicksilver Armor full stacked, reducing his damage taken by99%. The tank will need to drag him through the flowing lava in the middleof the room to damage his armor, giving him a stack of Superheated Quicksilver Armor for every 2 seconds he is under thelava. While under the lava, Karsh Steelbender will cast Heat Wave every second, dealing more for each stack of Superheated Quicksilver Armor. Because of Heat Waveand the Burning Metal damage he will be dealing while debuffedwith Quicksilver Armor, you will only want to briefly drag himthrough the lava to gain 1 or 2 stacks of Superheated Quicksilver Armor. If you keep him under the lava fortoo longer players will start dying from his increasing damage output.

Use as much crowd control as you have available on the pups, killingany besides Runty that you can not CC before focusing Beautydown.

Beauty will Berserker Charge the target that isfarthest away, and often uses Flamebreak to deal Fire damage toall nearby enemies. She will also periodically use Terrifying Roarto fear your group, which may cause someone to run into Runty andengage him in combat.

• Transformation
• Stone Blow

• Thunderclap
• Shadow of Obsidius

Ascendant Lord Obsidius will be protected by threeShadow of Obsidius, which can be attacked but do not take damage.These Shadows will ignore threat and only attack the player that most recentlyattacked them, with each Shadow applying Crepuscular Veil to theirtarget when they get close. These should be handled by having a DPS class withhigh mobility or DoTs to attack the Shadow of Obsidius clones andkite them around the room, ideally using any slows available to the group toavoid taking damage.

Ascendant Lord Obsidius will swap places with one of theShadow of Obsidius at both 66% and 33% health, so besure the group is ready to change targets. He will also cast Thunderclap often, slowing nearby members movement speed. If theplayer who is kiting the Shadow of Obsidius clones gets slowed bythis, quickly dispel them to allow them to properly kite. Lastly, eitherdispel the Twilight Corruption debuff or simply heal through it.
