The compositions of the spear heads wouldnt do much on earth, but within the cyberspace I can use all the materials and abilities of the spear! I can create barriers for protection, which i can also use to push viruses away! I can also drive the spear into the ground to make a powerful repulsive force, similar to an explosion of energy. It comes in mighty handy when your completley surrounded! The last abilities that I know of are energy pulses and a beam. All I need to do is to hit the handle against a wall, and hold it tight to send the vibration through the quartz,  it resonates at a specific frequency which within the cyberspace causes disruptions in the air which appears as a beam of energy. I can also tap the spear with my fingers for a similar effect to fire pulses of said energy, which is easier on your hands.
