You can keep your enemies at bay with reach weapons. You gain the following benefits:

• While you are wielding a weapon with the Reach property other creatures provoke an opportunity attack from you when they enter your reach.
• When a creature moves 15 ft or more while within your reach they provoke an opportunity attack from you.
• When you hit a creature with an opportunity attack, you can subtract your weapon damage and only deal your STR modifier and proficiency bonus as damage. This must be chosen before damage is rolled. When you choose this the creature must succeed a strength save of 8+ your STR modifier+ your proficiency bonus or the target's speed becomes 0 for the rest of the turn.
