I'm just getting into D&D. I'm looking at fighter and some of the things available to them and came across this:
- Shield Mastery allows me to knock back/shove an opponent I attack as a bonus action.
- Polearm Mastery allows me to attack with the base of my quarterstaff as a bonus action.
This is where things get a little hectic: if a monster moves within range of me, Polearm Mastery allows me to get an opportunity attack on them, but I don't understand to what extent.
How many bonus actions are you allowed per turn? If a monster comes within reach on their turn, can I hit them with my quarterstaff, knock them back with my shield potentially making them prone, then get an opportunity attack for my 2nd hit from the butt end of my quarterstaff?
