Project Lore

The Underbog is the second instance in the Coilfang Reservoir in Zangarmarsh, accessible through the easternmost entrance. Inside are a wide variety of enemy types, including beasts, elementals, giants, humanoids, and insects. A hunter's ability to trap most of these enemies is useful, as are mages and warlocks for their crowd control abilities. There are four bosses in the Underbog, and defeating enemies in Underbog gives Cenarion Expedition reputation. Heroic mode requires the Reservoir Key, purchasable in Cenarion Refuge.
