The first shot of the weapon is completely normal up until it is almost about to hit the ground. Right at that moment, a new shot forms out of the original one and makes a small shot that goes further away. Both the original and newly created shots do 20 damage and have a decent sized blast radius.
This tier acquires the same attributes as tier one, except it makes 3 extra shots instead of one. All new projectiles forming off of the newly created ones. Again, all of these shots do 20 damage and have a decently sized blast radius.
Triple-Jumper can be used as a good close range weapon against a single target if it is shot at a very steep angle causing all projectiles to contact the enemy tank.
Under specific conditions, this weapon will never spawn its new "jumping" shots and thus will only explode with only one projectile having existed.
