Oath of Leadership.

Paladins who swear the Oath of Leadership reject lofty idealism and swear a personal commitment to those under their charge. Whether they be sea captains, military officers, or mercenary leaders, these knights believe that command is a sacred contract of service and not a means to an end. Their oath bids them to protect, guide, and do right by those that would follow them.

Level 1 Features:

Tenants of Leadership.

The tenets of the Oath of Leadership demands a paladin do right by those who they are responsible for.
Burden of Leadership. You are in service of those who follow you, and you bear responsibility for the actions of your followers.
Chart the Course. A leader's duty is to chart a path forward. Be thoughtful, but decisive. Determine the necessary steps and follow through to the end.
Create Unity. The strength of many exceeds the strength of an individual. Bring people together toward a shared goal.
Lead by Example. Never give an order that you yourself would not follow.

Level 3 Feature:

Oath Spells.

Each oath has a list of associated spells. You gain access to these spells at the levels specified in the oath description. Once you gain access to an oath spell, you always have it prepared. Oath spells don't count against the number of spells you can prepare each day.
If you gain an oath spell that doesn't appear on the paladin spell list, the spell is nonetheless a paladin spell for you.

Channel Divinity: Captain's Command.

As a bonus action, you can use your Channel Divinity to call out to one creature you can see within 60 feet of you. If it can hear you, the creature can use its reaction to take the Attack (one weapon attack only), Dash, Dodge, or Use an Object action.
The number of creatures you can call out to when you use this Channel Divinity increases when you reach higher levels in this class, to two creatures at 7th level, three creatures at 15th level, and four creatures at 20th level.

Channel Divinity: Together We Triumph.

When you succeed on a saving throw against an effect that targets at least one other creature within 30 feet of you, you can use your reaction to use your Channel Divinity to choose a number of creatures up to your Charisma modifier (minimum of 1 creature) that you can see within 30 feet of you. If a chosen creature can see or hear you, it automatically succeeds its the saving throw against the triggering effect. You can choose to use this Channel Divinity after all the saving throws are rolled, but before the outcomes are determined.

Level 7 Feature:

Aura of Morale.

Starting at 7th level, you radiate an aura of confidence that inspires those who follow you. When you score a critical hit or reduce a creature to 0 hit points, you can choose any number of creatures other than yourself within 10 feet of you. If a chosen creature can see or hear you, it gains temporary hit points equal to your Charisma modifier (minimum of 1 hit point), which last for 1 minute. While a creature has these hit points, it has advantage on attack rolls and ability checks.
At 18th level, the range of this aura increases to 30 feet.

Level 15 Feature:

Aegis of Trust.

Starting at 15th level, those who follow you are protected by their trust in you. While a creature has temporary hit points granted by you, it has resistance to all damage.

Level 20 Feature:

Commanding Presence.

At 20th level, you can manifest divine power to become an avatar of unquestionable authority. You can use your action to gain the following benefits for 1 minute:
-You can cause your voice to boom up to ten times as loud as normal and be audible from up to 1 mile away.
-When you deal damage to a creature with your Divine Smite, you can mark it for your allies to strike down. Until the start of your next turn, the creature takes an additional 1d8 radiant damage whenever it is hit by an attack.
-You can cast Command as a bonus action on your turn, without expending a spell slot.
Once you use this feature, you can't use it again until you finish a long rest.
