Jsk Duty of the Guardian

Guardian Aegis
At 3rd level, your Aegis feature is improved. While you wield a shield, all damage you take from Attacks is reduced by 2, excluding psychic damage. This damage reduction increases as you gain levels in this class (see the Aegis column of the Warden Feature Table).

Self Sacrifice
At 3rd level, you can put yourself in harms way to protect other creatures. When an effect or a spell targets multiple creatures at once with a Strength, Dexterity, or Constitution saving throw, and you are one of those creatures, you can use your Reaction to protect those closest to you. You can choose one of the following options.
 * You make the saving throw with disadvantage. In exchange, creatures of your choice within 5 feet of you make their saving throw with advantage.
 * You automatically fail the saving throw. In exchange, one creature of your choice within 5 feet of you automatically succeeds on their saving throw.

Guardian Mandate
At 6th level, your ability to protect people of importance is exceptional. No creature that you can see can make an Attack against a creature with advantage if the target of that Attack is within 5 feet of you, unless you allow it.

Area Control
At 11th level, you have an unlimited number of special reactions to use each round. A special reaction can only be used to make an opportunity attack, or to use a Martial Ability that you know.

Presence of the Guardian
At 15th level, you can bolster and inspire your allies to perform at their very best (no action required). You gain a non-magical aura centered on you that extends out to 15 feet. When you move, the aura moves with you. At the start of each of your turns, creatures of your choice within the aura, including you, gain the following benefits. These benefits last until the start of your next turn. Your aura lasts for 1 minute, and ends early if you are incapacitated. You can also choose to end your aura early on your turn as a bonus action. Once you have used this feature, you cannot use it again until you have finished a long rest.
 * When a creature is targeted by an Attack for the first time on a turn, the attack is made with disadvantage.
 * A creature can take the disengage action as a bonus action.
