needs a trail, probably a shorter cooldown and to make you move way faster and negate gravity slightly but stop suddenly and really only go that distance in the first place. in addition the final explosion should always occur at the end of the attack even if it doesn't connect with a target because hitting a lagging target is hard as stuff and hitting vaguely near them to do damage is way easier
like it should essentially be a manually-aimed homing attack
also it shouldn't make you raise your hand, but when you first open it up the saw tomahawk's TIING goes off and the little spark comes from your eye
