This battle exercise will test your ability to breach enemy stronghold defenses. Eliminate targets in each of the three antechambers before infiltrating the final chamber and engaging the cyclopean toad who makes the cave its den. Making quick work of the creature is key, for the yarzons who lurk behind the chamber's boulders will emerge once they smell blood.
Some gates will open automatically after all enemies have been defeated and the area is secure. There are, however, other gates which can only be opened using a lever.
When you arrive in the final chamber, yarzons will attempt to break through the boulders they are trapped behind. Finish off the ledgeleaper before the vilekin can join the fray.
