 * Sways back and forth while moving towards the player, lunging quickly whenever the tip of the blade is pointing at them.

 * Stabs into the ground, shaking the screen, and causes several waves of massive blades to erupt from the ground. These blades are telegraphed by red warning beams.

Below 50% HP, Imperious gains a dark tint and starts exclusively using the following attacks.


 * Flies very high into the air and summons four rings of 7 massive phantom blades around the player, which slowly converge on them. Imperious will take the place of the top blade in the last ring and emerge once the ring converges.
 * Repeats its first attack but also leaves behind damaging afterimages while moving.
