Polearm Master - Hook Bonus Attack

When you take the Attack action and attack with only a glaive, halberd, quarterstaff, or spear, you can use a bonus action to make a melee attack with the hook side of the weapon. This attack uses the same ability modifier as the primary attack. On successful attack, you hook your target and attempt to sweep them prone. Target must pass a DC 16 DEX check or be knocked prone
