Barrel of Monkeys

Barrel of Monkeys is a raid achievement earned for defeating Grong, the Jungle Lord for the Horde or Grong, the Revenant for the Alliance in Battle of Dazar'alor on Normal difficulty or higher, after having Grong smash 6 barrels.

The barrels are located about the boss arena and can be picked up and moved by interacting with them. They are destroyed by Reverberating Slam and Deathly Slam, but doing so grants Grong a stacking buff which gives him 20% extra damage dealt, per stack.
