Your duty is to protect your allies during and hold the line. You can gain the following features:

Ability Score Increase. Increase your Strength, Dexterity, or Constitution by 1, to a maximum of 20.

Immovable. When you or a creature within 5 feet of you are subjected to an effect that would forcefully push a creature, you can reduce the distance pushed by 10 feet.

Active Aegis. While wielding a shield and not Incapacitated, you can choose up to a number of targets, other than yourself, equal to your Proficiency Bonus within 5 feet of you. Each target can add your shield’s AC bonus to their own AC and can reduce any damage taken (except Psychic damage) by an amount equal to your Proficiency Bonus (to a minimum of 0 damage).
