Abyssal anchor

Abyssal anchors appear during Heart of Stone in the final boss fight against the Prehistoric abyssal. During the fight, any attempt at attack the abyssal will fail because of his invulnerability, however, as the battle continues, Kipple will occasionally find weaknesses in his armor and make them visible to the player. These weaknesses appear on the map as abyssal anchors, and the player must destroy three of these to do damage to the abyssal.
