Let me think this through: the basic principle of affecting reality with spiritual means requires:
- spiritual energy
- spiritual attributes
- will of an entity
In this case the attributes of annihilation came from the blade, directed by Sharpie and Ketis while using her spiritual energy. Right?
How dare you blame Sharpie for what you did yourself young lady? I am glad you are not an idiot. Figuring it out should prevent you from becoming a rational mech designer.
It looks like she can expand her specialization to melee weapons, switching her philosophy like a revolver. Sharpness, destruction, blocking, flexibility, etc.
