Level 64

This is the fourth stage you will fight on this island. This stage is basically Obsidia Hell but with higher levels and only one wave.

Strategy
Level 27 was a very annoying stage. This stage, however, should be easy by the time you get here since you will probably have Arch Knight who can counter each and every annoying thing about Obsidia. He is Immune to Blind and can deal very heavy damage to the Obsidias. He can also heal his team and shield them. He could potentially solo this level on his own.
