Lost Cavern, a new Battleground featuring just one lane —and a whole lot of team fighting— is now available for play exclusively in Custom Games! * Lost Cavern has no Mercenary Camps, and just one objective: Battle through the opposing Fort, Keep, and Core to claim victory. * Players cannot use Hearthstone and will not heal at the allied Hall of Storms. * Corridors on either side of the lane contain neutral Regeneration Globes, which will respawn regularly throughout the game.
