Assault on Violet Hold

Blood-Princess Thal'ena immediately uses [Vampyr's Kiss] to infect an enemy with [Essence of the Blood Princess]. When [Essence of the Blood Princess] wears off, the victim has a short amount of time to infect another target. If they cannot do so, they submit to [Uncontrollable Frenzy].

Festerface spews torrents of nasty bile that form into Congealed Goo. When a Congealed Goo is killed it begins to reform and will fully heal after a few seconds. During this time, Festerface can consume the Congealed Goo if he is brought close to it.

Shivermaw uses powerful Frost magic, forcing players to move between the upper and lower sections of the prison to avoid [Relentless Storm] and [Ice Bomb].

Anub'esset attacks the party and calls scarabs and beetles to assist him in battle. Players must quickly eliminate his minions before becoming overwhelmed.

On Heroic difficulty, Blistering Beetles will burrow into the fight, fixating on nearby players. When they come into contact with a player or die, they will explode, creating a pool of Blistering Ooze.

Once released from her magical prison cell, Millificent Manastorm uses her technological gadgets to overpower her enemies.

Mindflayer Kaahrj attacks the party with his Shadow Crash and Hysteria spells. At 80% and 40% health, Mindflayer Kaahrj casts Eternal Darkness, ushering in a swathe of Faceless Tendrils to repeatedly damage party members.

Fel Lord Betrug periodically sends players flying to the extreme sides of the Violet Hold. One of these players is chosen for Execution and must be freed or else they will die.

Sael'orn pulls her enemies close to her while attacking them with viscious short ranged attacks. Periodically, her invulnerable phase spider guardians join the fight, attacking enemies foolish enough to turn their backs.
