The Ravenian

Lower study rooms
Descend to The Ravenian, Lord Alexei Barov and Lady Illucia Barov. Prepare crowd control for Alexei's linked guards before approaching him, and clear Illucia's surrounding enemies before Fear can send someone into them. Finish the remaining chambers before returning to the central study.

The Ravenian
Elite UndeadThe Ravenian tests sustained tank healing as Sundering Cleave reduces armor while Knock Away disrupts the tank's position.
Abilities

Sundering Cleave
Keep players other than the tank out of Sundering Cleave's adjacent targets, and prepare mitigation as its armor penalty accumulates.

Knock Away
Inflicts normal damage plus 30 to an enemy and knocks it back.
Tank with a cleared wall behind you to contain Knock Away rather than being pushed across the study.

Trample
Inflicts Physical damage to nearby enemies.
Trample damages nearby players. Keep ranged attackers and the healer outside close range rather than adding them to the tank's healing load.
Tank- Use a wall to contain Knock Away and keep Sundering Cleave off nearby teammates. Use mitigation as the armor penalty grows rather than treating the opening swings as the fight's maximum damage.
Healer- Stay out of close-range Trample and expect the tank to need more healing as Sundering Cleave accumulates. Keep the tank's wall position within reach after Knock Away.
Damage- Attack away from the tank's cleave position. Ranged attackers should remain outside Trample while maintaining damage so the tank spends less time under the stacking armor penalty.
