Oath of the Imperium

Potential paladins of the imperium study magics that can counter and control the flow of magic around them or directed at them. The senior council of the imperium assign aspiring spellcaster to the paladins who want to join their elite ranks.

Learning magic that is not well known and sometimes frowned upon by other paladins. Recruits spend their time reading over books and learning from tutors on how to warp magic energies against the spellcasters who cast magic towards them, sometimes nullifying sometimes redirecting.

When a paladin is bonded with an aspiring spellcaster the two have the ability to warp to each other regardless of distance, The bonded spellcaster also gains a +1 to AC.

Taking this oath at 3rd level gives you the arcana skill proficiency.

Channel Divinity

• Nullifying Aura: You can use you Channel Divinity to exude a 10ft aura of nullifying negative energy, the aura follows you wherever you move, cancelling out magic from all sources except yourself, Spellcasters caught within the aura lose the ability to cast spells, No magic can be cast within the aura nor can any magic pass into it, if the creature affected leaves the aura they can cast normally again. The paladin can cancel the effects at any time but the aura last for 1 minute.
• Imperium's Judgement: You can use your Channel Divinity to infuse your weapon with negative energy, when you make an attack roll you unleash the stored energy upon any spellcasters to silence them until the end of your next turn, When struck spellcasters can't use any magic unless they succeed on a Charisma saving throw against the paladins spell save DC.
