Question about the Polearm Master Feat. The first bullet point says (PHB, p. 168, bold added):
- When you take the Attack action and attack with only a glaive, halberd, or quarterstaff, you can use a bonus action to make a melee attack with the opposite end of the weapon.
Imagine you are a 5th level fighter with this Feat, and you take the Attack Action while wielding a quarterstaff:
- First attack: used to Shove your opponent
- Second attack (from Extra Attack): attack with your quarterstaff
Could you then get the bonus action attack? I'm not sure if the "only" in Polearm Master's text would preclude this or not (it's unclear if it mean you can't attack with other weapons, or that you can't take any actions other than polearm attacks.)
NOTE: This question is further complicated by the fact that it's ambiguous whether or not you can shove with your quarterstaff (since Shove does not require a free hand, and a target must be "within your reach" [PHB, p. 195]). And before an answer comes along saying otherwise, a Shove is an attack, since the rules say
you can make a special melee attack to shove a creature... If you’re able to make multiple attacks with the Attack action, this attack replaces one of them. (PHB, p. 195, bold added)
And Jeremy Crawford has stated "Is something an attack? Yes, if... the rules expressly call it an attack."
