The Oath of the Arcane is sworn by those who wish to carry out the goals of those who are true masters of arcane powers, while not wishing to become a master themselves. Often called Arcane Warriors or Eldritch Bulwarks, they who swear the oath vow to protect the mission of eldritch powers and block attacks against their mage masters. Though they are far arcane power from the exemplars that are wizards, sorcerers, and warlocks, they do gain some eldritch magic from the oath that they uphold.

Though Eldritch Bulwarks do vow to protect masters of arcana, they do not hold this to be a universal law amongst their orders. Some of these paladins do choose to protect any mage under nearly any conditions, but most are more selective, choosing masters to serve depending on their goals, alignment, ideals, and other important factors. In many worlds there are paladins who devote themselves to divine orders, but it is rare to find paladins who serve arcane powers. In Toril, they may swear themselves to the Weave, Mystra, Azuth, or an ancient Netheril wizard or lich. In Eberron, knights of this order may serve the Ring of Siberys, The Shadow, Sul Khatesh, or the Wizards of Arcanix. IN Exandria, these knights may serve the Cerberus Assembly, the Luxon, or another arcane power. In Tor-eal, the Yikkan Goblinoids have many servants of the Yikare, and Oath of the Arcane paladins are relatively common. Others of this order in Tor-eal may swear themselves to Vecna, Zilya Darkcord, or the master artificers of Lantan. 

TENETS OF THE ARCANE

The tenets of the Oath of the Arcane focus on protecting arcane masters and spreading the touch of eldritch magic. 

Resilience. Be the bulwark that deflects the attacks of the forces of chaos when they target masters of the arcane powers. 

Eldritch Might. Arcane power will preserve the foundations of the world as long as it has worthy followers. As eldritch magic spreads through the world, it will become a better place, a haven to masters of arcana. 

Spread the Word. Be a missionary of the arcane masters, recruit all who are willing to study arcane magic, and strengthen the roots of magic in the realm. Never force and never preach. Instead, be an example to those who do not follow the Art, and practice magic in patience. 

Exorcism of Psionics.Crush all those who practice the abomination that is psionics. Psychic powers are alien and must be destroyed before they can disease the land around them. Never allow a psion or aberration to escape your grasp. 

Channel Divinity

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

Arcane Empowerment. When a creature within 30 feet of you (including you) casts a spell using a spell slot, you may use your reaction to cause the spell to come into effect without expending a spell slot, using your Channel Divinity instead. The spell slot used to cast the spell must be of a level equal to your proficiency bonus or lower. 

Eldritch Weapon. As a bonus action, you can imbue one weapon that you are holding with forceful arcane energy, using your Channel Divinity. For the next minute, when you hit with this weapon, all damage that you deal with its attack deals force damage. Additionally, it deals extra force damage equal to your proficiency bonus. 

If the weapon ever leaves your hand, you can choose to teleport it instantly back to your hand (no action required). If you are ever incapacitated, this effect ends. Additionally, if you take damage from a creature within 30 feet of you, you may end this effect as a reaction, dealing force damage to the creature equal to 2d10 + your paladin level. 

Oath Spells

Oath of the Arcane Spells

Aura of Arcana

Beginning at level 7, eldritch power surrounds you, causing others to have a more difficult time avoiding spell effects. Each creature of your choice within 10 feet of you has disadvantage on saving throws against spells and other magical effects. 

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

Mimic Magic.

Starting at 15th level, when a creature within 60 feet of you casts a spell, you may quickly learn how to cast that spell. If the spell is of a level you can cast, it becomes a paladin spell for you and you prepare it, not counting against the amount of spells you can normally prepare. Sometime before you take a long rest, you may cast any spell prepared this way once without expending a spell slot. You may use this feature an amount of times equal to your Charisma modifier (minimum of once), regaining all uses when you take a long rest. At the end of a long rest, you forget all spells prepared this way. 

Eldritch Bastion

At 20th level, you can harness your inner arcane power to become an embodiment of eldritch energy, causing your eyes to glow and your body to float. As an action, you gain the following benefits for the next minute: 

• You gain a flying speed of 60 feet and can hover. 
• Whenever you cast a paladin spell that has a casting time of an action, you can instead choose to cast it using a bonus action.
• When you deal damage with an attack or spell, instead of rolling damage, you deal the most damage possible. 

Once you use this feature, you cannot do so again until you finish a long rest.
