Vengeful Chicken

To collect this pet, players need to enter the Waycrest Manor 5-man dungeon when the World Quest, Waycrest Manor: Witchy Kitchen is active. The group must pull the 3 quest NPCs in the kitchen, and keep them alive until they complete their "cooking" process. Executive Chef Daniel does not have to be kept alive.

Roast Chef Rhonda needs to spawn a Raw Chicken
Roast Chef Rhonda needs to cast Roasting Fire on top of Raw Chicken, resulting in a Cooked Chicken
Sauciere Samuel needs to cast Gravy Spray on Cooked Chicken, resulting in Delicious Chicken

After the above steps are complete, players can defeat the kitchen staff (killing them is not necessary), and all group members should be able to accept a quest from the Delicious Chicken.
