Shield Dash

Holding down the shift/crouch button, and double clicking/tapping the forwards, backwards, right and left movement keys makes the player dash in any direction for a brief second. This mechanic would give players an actual way to dodge melee and ranged attacks when trying to back away from an enemy. Shield dash can also be used to bump into your enemy. This would have a 20 percent chance of stunning your enemy, and also giving you a chance to attack. Other than this, it will always knock back the player at the receiving end of the Shield Dash.
