Banshee
Banshee is a boss that can appear in the Boneyard on the second floor.
Attack Pattern
This Boss has 2 Attack Patterns.
1st phase:
Pattern 1:
It moves in a straight line towards your position until it reaches a wall. This is repeated until the end of the pattern.
During that, it will launch a pair of projectiles at you. They create a small shockwave on impact.
This is repeated 4 or 5 times.
Pattern 2:
It teleports into the corner that is the furthest away from you and launches a big blue ball that splits into 10 smaller balls on impact.
The fan pattern that they spread out in is aimed at you, but because it's an even number, they will not hit you if you don't move.
2nd phase:
Pattern 1:
The launched projectiles now leave behind 3 or 4 red balls on impact.
Pattern 2:
The big ball changes color to red. Instead of 10, it now splits into 8 small red balls and 7 bigger blue ones.
