When the energy of the Corruption fueling Nightmare gets too high Nightmare grows stronger. Extra ears to hear behind him, and extra eyes to see even more enemies.

When Basalt is overtaken by corruption or crystal stability is dropping too low, he enters Darkness Form, which is a dangerous phase to be dealing with. The higher the phase the harder.

"How can this be? Is Basalt...truly corrupted? No, there's still time! The glowing essence of his soul is fighting back! There's no time to waste; give it your all and save a new friend!"
