Doctor Theolen Krastinov

Upper study rooms
Work through Malicia's classroom, Krastinov's room and Polkelt's room around the upper level of the study. Finish each chamber before moving on. These rooms can later receive a player separated by Gandling's Shadow Portal, so leaving ordinary enemies alive creates a second fight for that player.

Doctor Theolen Krastinov
<The Butcher>Elite HumanoidKrastinov tests whether the tank and healer can survive Rend continuing through Backhand, then keep enough resources for Enrage.
Abilities

Rend
Inflicts Physical damage to an enemy every 3 sec. for 15 seconds.
Rend keeps dealing Physical damage after the initial application. Account for the bleed when judging whether the tank is safe through a stun.

Backhand
Backhands an enemy, stunning it for 2 seconds.
Backhand stuns the target. Keep the tank's health high enough that the ongoing Rend does not require a defensive action during the stun.

Enrage
Save mitigation, healing resources and burst damage for Enrage, when Krastinov's melee attacks become more dangerous.
Tank- Keep a defensive ability for Krastinov's Enrage. Do not count on being able to react after Backhand lands while Rend is still ticking.
Healer- Maintain enough health on the tank to cover Rend through Backhand, then increase healing when Enrage starts. The bleed continues while the tank is stunned.
Damage- Save burst for Enrage to shorten the period of increased melee pressure. Avoid a threat change that leaves an unprepared player taking Krastinov's attacks and Rend.
