The Iskaara Soup rewarded after the Community Feast event is one of the best additions to World of Warcraft in a long time. Players will have 10 minutes to finish tasks for the Chef as you slowly level up the quality of the soup. Eventually, you'll finish, kill an elite mob and finish the event. Afterward, you can continue to drink the soup to earn a buff.
The buff lasts for one hour and doesn't replace your own food, so you can eat stat food and the community feast as well, but the questions remains, can you use it in instances and raids.
Does Iskaara Soup Work in Dungeons and Raids?
The buff does not work in instances and raids. As the buff states, "Killing a creature in the Dragon Isles grants you and a nearby player Spirit of Sharing." That means only in the open world of the Dragon Isles. It would be a little too powerful if it was able to stack inside of raids. But this is pretty incredible for the many different world farming events. Players looking to get keys, motes or hunts will enjoy the buff.
