Guardian

Your battlefield awareness and quick reflexes allow you to control the area around you, making it difficult for enemies to bypass you. You gain the following benefits:

• When a creature within 5 feet of you makes an attack against a target other than you, you can use your reaction to make a melee weapon attack against that creature.
• Creatures within 5 feet of you have their speed reduced by half.
• If you hit a creature with an opportunity attack, you can choose to reduce their speed to 0 for the rest of their turn.
