All About The Super Arrow

The Super arrow takes two points of ammo to fire, though it can be fired with only 1 point of weapon energy remaining.

You cannot walk (or slide) off the front of a moving arrow - it will catch you.

Riding the Super Arrow drains 1 point of energy as Mega Man is on it. As such, many strats in this game walk off the front of the arrow, reducing the time Mega Man is technically still riding it, and conserving "just enough" ammo.

You can stand on an arrow stuck to a wall until it despawns without draining ammo.
