You have become an expert in handling polearms such as halberds, glaives, and quarterstaffs. You gain the following benefits:

• When you take the Attack action and attack with only a polearm, you can use a bonus action to make a second attack with the opposite end of the weapon. This attack uses the same ability modifier as the primary attack but deals bludgeoning damage and has a damage die of 1d4.
• If a creature enters your reach, you can use your reaction to make an opportunity attack against it. This attack uses your polearm.
• When you successfully hit a creature with a polearm, you can attempt to push the creature up to 10 feet away from you. The target must succeed on a Strength saving throw (DC 8 + your proficiency bonus + your Strength modifier) or be pushed.
