Lorekeeper Polkelt

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.

Lorekeeper Polkelt
Elite UndeadPolkelt tests whether the group separates and cures Volatile Infection before Nature vulnerability turns its repeated splash damage into a group problem.
Abilities

Volatile Infection
Move the infected player away from allies and cure the disease when possible; Volatile Infection makes its carrier damage nearby teammates.

Noxious Catalyst
Noxious Catalyst reduces Nature resistance. Cure it when possible, and avoid exposing its target to an infected teammate's splash damage.

Corrosive Acid
Corrosive Acid reduces armor. Remove it from the tank when possible instead of treating it as another disease; it is a magic effect.
Tank- Keep Polkelt in a stable position so an infected player has room to move away from the group. Request Corrosive Acid removal when its armor penalty increases the melee damage you take.
Healer- Cure Volatile Infection and Noxious Catalyst if your class can remove diseases. Corrosive Acid instead needs magic removal; prioritize the tank if the armor loss is threatening them.
Damage- Separate from allies when Volatile Infection lands on you and remain apart until it is removed or ends. Avoid standing beside an infected player while Noxious Catalyst has reduced your Nature resistance.
