Plaguemaw the Rotting

The Murder Pens and idol
Clear the prison passages before starting the optional prisoner escort. If the prisoner offers it, follow the escort back toward the gong area and stay for the defense at the idol. Plaguemaw arrives at the end of the ritual; do not leave the prisoner to chase attackers down an uncleared passage.
Plaguemaw the Rotting
Elite HumanoidPlaguemaw ends the prisoner-defense event with a nearby silence and a mana-draining disease while the group must still protect the prisoner.
Abilities

Putrid Stench
Reduces nearby enemies' Strength by 50 and Agility by 50 for 10 seconds., as well as preventing them from casting spells.
Keep the healer and ranged casters outside Putrid Stench. It prevents spellcasting as well as reducing Strength and Agility.

Withered Touch
Remove Withered Touch from affected mana users instead of only healing its damage; the disease also transfers their mana to Plaguemaw.
Tank- Intercept ritual attackers before they reach the prisoner. When Plaguemaw arrives, hold him apart from the healer so Putrid Stench does not silence the group's healing.
Healer- Heal from outside Putrid Stench's reach. Remove Withered Touch from mana users when you can; otherwise call for disease removal before the drain costs them their next casts.
Damage- Leave Plaguemaw to stop an attacker hitting the prisoner. Ranged casters should remain outside Putrid Stench, and a player with disease removal should clear Withered Touch from the healer.
