Battle Master maneuvers can give to-hit modifiers, attack advantages, damage bonuses and various effects to regular attacks.
My question is : can they do the same for Shoves (trips & pushes) and Grapples, which are classified as "special attacks" ?
Examples :
- Applying a Precision Attack maneuver to a Shove-Trip roll;
- Getting an advantage on a Grapple thanks to a Feinting Attack
maneuver; - Using the Disarming Attack maneuver during a Shove-Push;
- Adding the Menacing Attack maneuver effect to a Grapple;
etc.
Note 1 : although this question is related, it pertains to Pathfinder instead.
Note 2 : It is probably up to your DM whether a Shove can be made with a weapon, and although a Grapple must be made with a free hand, it is currently unconfirmed whether Battle Master maneuvers requiring a weapon can be applied to an unarmed attack.
Best Answer
No
Each of the maneuvers you have listed clearly state either
or
Emphasis Mine.
Grapple, Shove, and Trip are all Athletics checks, not weapon attacks. Therefore, you are not making a weapon attack roll, or hitting with a weapon attack. You are performing an Athletics check to grapple, trip, or shove.
See the definitions of Grappling and Shoving a Creature on PHB 195, and Attack Rolls on PHB 194. A Grapple or Shove is a distinct type of attack from a Weapon Attack. The presence of 'weapon' in those maneuvers is there to indicate that the maneuvers only work when you make a Weapon Attack. Not when you make any attack.
This is the same rule that prevents things like grappling with Green Flame Blade, or Sneak Attacking with a Shove.
