Base Class: Paladin
When tyrant's wage wars of conquest, many people retreat to castles and fortresses in small hope that they will survive the fires that will ravage their homes. But sometimes it is not possible to merely survive a despots armies. Sometimes the only options is to fight or die. Unconquered Paladin's are soldiers who dedicate themselves to defending the ideals of freedom and prosperity and fighting those who would use strength to subdue and rule the weak. Commonly called Bulwark Knights, Mountain Knights, and the Unbroken, these soldiers stride into battle with defensive magics alight, making them mobile fortresses that can withstand the wrath of mortals, kings, and gods.
Adamantine Bulwark
Anytime you take damage from an attack or spell, you can use your reaction and your channel divinity to reduce all damage to you by an amount equal to three times your paladin level.
Unstoppable Tilt
You may spend an action to use your channel divinity in order to move up to your speed in a straight line. You can move through enemy creatures, and the first enemy creature you come in contact with must make a strength saving throw equal to 8 + your proficiency + your strength modifier or they take 2d8 bludgeoning damage, and is forcefully moved along with you until you finish your movement. On a successful save they take no damage and are not moved. All other creatures you pass through, or the creature you are carrying, must also make the save or be knocked prone.
Aura of Iron
Beginning at 7th level, you emanate so many protective magics that it is almost palpable. You and creatures you choose within 10ft of you; reduce all damage they take by an amount equal to your charisma modifier(minimum 1). At 18th level, the range of this aura increases to 30ft.
Living Fortress
At 15th level, you have become as tough as the mightiest fortress, and embody many of its qualities. You can no longer be restrained or forcefully moved. Additionally, allies that are adjacent to you, and are of your size category or smaller, have your AC when they are targeted by an attack.
Unbreakable Defender
At 20th level, you may spend an action in order to create an additional, secondary layer of armor made up of solidified arcane energy that appears over your armor. For the next minute, you gain the following benefits:
•If an attack or spell deals 15 or less points of damage to you, ignore it.
•Anytime a hostile creature makes a ranged attack against an ally within your Aura of Iron, roll a d6. On a 4, 5, or 6, the attack is made against you instead.
•Allied creatures in your aura always gain the benefits of half cover.
Once you use this feature, you cannot use it again until you finish a long rest.
