Mountain Heart Chest

Mountain Heart Chest will spawn after defeating Cyndr the Mountain Heart or Magmus in the final level of the Heart of the Shiverpeaks dungeon. Each player in the party may open the chest and will receive one item from the drop list in normal mode (2 in hard mode). After the chest has been opened by every player, a countdown timer will begin and the party will be teleported outside the dungeon after three minutes.
