Polearm Savant

You’ve honed fighting with hafted weapons, including glaives, halberds, pikes, quarterstaffs, or any other similar weapons.

• Creatures entering your threatened area provoke attacks of opportunity while you are wielding a hafted weapon.
• You may expend your bonus action to make a haft attack after taking the attack action with a hafted weapon. This attack uses the same attribute modifier as the primary attack and inflicts a d4 bludgeoning damage.
