Hearthsinger Forresten

Stratholme
From the main gate, clear the streets toward Festival Lane and Market Row without crossing the next arch during an existing pull. The Unforgiven ambush brings Vengeful Phantoms into the street. Check for Hearthsinger Forresten and Skul while travelling, but do not depend on either rare appearing. Ezra Grimm's tobacco box and the postboxes are deliberate side encounters; clear their surroundings before interacting.

Hearthsinger Forresten
Elite UndeadHearthsinger Forresten combines a breakable sleep with ranged volleys, so the group must preserve a working healer without standing together around the shooting target.
Abilities

Enchanting Lullaby
Lulls an enemy to sleep for up to 10 seconds. Any damage caused will awaken the target. Only one target can be asleep at a time.
Interrupt Enchanting Lullaby; if it lands, a magic dispel can return the sleeping player to the fight.

Multi-Shot
Leave space around the current target so Multi-Shot does not catch the healing position as well.

Demoralizing Shout
Demoralizing Shout weakens weapon damage; keep spell damage on Forresten while the melee attack-power penalty lasts.

Shoot
Shoots at an enemy, inflicting Physical damage.
Establish the pull in a cleared street so ranged shooting does not draw the group into another pack.

Incorporeal Defense
Incorporeal Defense increases dodge; spell damage avoids that obstacle to weapon attacks.
Tank- Bring Forresten into the cleared street and leave room behind the shooting target for the healer to stand apart. Do not chase the ranged fight through an uncleared arch while an ally is asleep.
Healer- Stand apart from the shooting target to avoid sharing Multi-Shot. Remove Enchanting Lullaby from an ally when possible; arrange another player's magic dispel if the sleep catches you.
Damage- Reserve an interrupt for Enchanting Lullaby and spread away from the shooting target. Spell attacks keep contributing through Incorporeal Defense and Demoralizing Shout.
