Guardian*

You have mastered techniques to take advantage of every tell and telegraphing of any enemy's attack, gaining the following benefits:

• While carrying a shield, when a creature attacks a friendly entity within 5 feet of you, you can use your reaction to attempt a DC 15 roll to protect your ally with your shield. The target ally takes half damage on a successful save.
• If a friendly creature within 5 feet of you is also carrying a shield you can form a shield wall. Attacks against either of you are now made at disadvantage.
• If a friendly creature within 5 feet of you has also learned this feat, you can use your bonus action to hamper an enemy within 5 feet, reducing their movement to 0 for a single turn.
