Oath of the Aegis

Tenets of the Aegis:

Bravery: A castle does not yield, do not bow in the face of opposition, but rise to meet it.

Comradery: A blade may have a single edge, but a shield must be broad. Do not take upon yourself the burden alone.

Fervor: First to the fight, last from the field. Action is demanded of you, a moment of laxity and the line is broken.

Protection: To shield allies from harm is tactically wise, to shield innocents is absolute.

Channel Divinity

When you take this oath at 3rd level, you gain the following two Channel Divinity options.

Bolster Allies: As an action, you can strengthen the resilience of your allies, using your Channel Divinity. Select a number of creatures you can see within 30 feet of you, equal to your charisma modifier (minimum of one creature). Each creature gains temporary hit points equal to your paladin level + your charisma modifier.

Blunt the Offensive: You can use your channel divinity to foul your opponent's strikes. As an action, you can force a number of creatures you can see within 30 feet of you, equal to your charisma modifier (minimum of one creature) to make a wisdom saving throw. On a failed save the creature is weakened and subtracts your Proficiency Bonus from it's attacks. A weakened creature repeats this save at the end of each of it's turns. 

Aura of the Stalwart

At 7th level you emit an aura of grit and resilience while you aren't incapacitated. When you and any creatures of your choice within 10 feet of you roll initiative, you all gain temporary hit points equal to your Proficiency Bonus your Charisma modifier (minimum of one). 

At 18th level, the range of this aura increases to 30 feet. 

Unyielding Defense

At 15th level your determination is so great you can shake off effects that would leave a lesser warrior reeling. When you fail a saving throw imposing a status condition, you may instead choose to succeed instead. Doing so imparts one level of exhaustion onto you. You can use this class ability a number of times per day equal to half your proficiency bonus

Living Fortress

At 20th level you can imbue yourself with the ultimate defense, a shimmering ward encompassing your form and radiating into your immediate surroundings. Using your action you manifest the ward and gain the following benefits for one minute:

You gain resistance to all damage.

When an enemy hits you with an attack, their speed is halved.

Allies within 10 feet gain resistance to piercing, slashing, and bludgeoning damage.

Once you use this feature you cannot use it again until a long rest.
