====Shield Bash====
: When you perform a shield bash, you may still apply the shield's cover to your Defense.
: '''Specialist:''' Any shield bash you make with a small or large shield also affects your opponent as if you had performed a bull rush. You don't actually move into your opponent's square or incur attacks of opportunity for the bash. You also can't move your opponent back more than 5 feet, nor can you move along with the defender. You can't use this feat with a buckler.
: '''Expert:''' You can now move with your opponent that you bull rush.
