Channel Divinity

When you take this oath at 3rd level, you gain the following two Channel Divinity options.
Tide of Stone. As a bonus action, you can use your Channel Divinity to beseech the earth for aid, ensnaring your foes and pushing them back. Creatures of your choice within 15 feet are pushed up to 10 feet away from you. For one minute or until you end this effect (no action required), the ground around you in a 15 foot radius is considered difficult terrain for creatures of your choice. The radius moves with you, centered on you.
Unbreakable. You can use your Channel Divinity to call upon the strength of ancient stone and stand where others would fall. When you are reduced to 0 hit points but not killed outright, you can choose to drop to 1 hit point and gain temporary hit points equal to your paladin level + your Charisma modifier instead. Additionally, you have resistance to bludgeoning, piercing and slashing damage until the end of your next turn.

Aura of Resilience

Starting at 7th level, you and all friendly creatures within 10 feet of you have advantage on saving throws against being forcefully moved, and can't be knocked prone.
At 18th level, the range of this aura increases to 30 feet.

Earthen Barricades

Starting at 15th level, you can summons walls of stone to intercept attacks. As a reaction when a creature within 30 feet of you takes damage, you can summon an earthen wall to absorb part of the damage. The triggering damage is reduced by half your paladin level + your Charisma modifier.

Mountains Might

At 20th level, you can take on aspects of the earth becoming even mightier. Using your action, you undergo a transformation. For 1 minute, you gain the following benefits:

• The ground in a 15 foot radius around you rumbles and shifts, creatures of your choice moving through the area must spend 4 feet of movement for every 1 foot it moves.
• When you hit a huge or smaller creature with a melee weapon attack it is knocked prone.
• At the start of each of your turns, you regain 10 hit points.

Once you use this feature, you can't use it again until you finish a long rest.
