Oath of the Old Ones

As a paladin, you follow an oath that leads you to become a true warrior of your faith. Sometimes, that leads you to dark corners; shadowed halls where the whispers lay.

Calm. You have discovered that your existence is worthless. And yet with that realization, you are unburdened.

Compassion. To live is to suffer. Suffer for others so that you may help give them eternal rest.

Contemplation. Although you are but a glimmer to history, you have received revelations beyond your years. Think deeply and consider it all.

Continuity. Do not falter, do not yield, and give no quarter. Go on and go forth unto the never-ending river of time.

Channel Divinity

When you take this Oath at 3rd level, you gain the following two Channel Divinity options as well as the Eldritch Blast  and the Vicious Mockery Cantrip.

Forbidden Precept

As an action, you can imbue a weapon(s) that you are holding with aberrant energy, using your Channel Divinity. For 1 minute your attacks now deal an extra 1d8 force or psychic damage. This increases by 1d8 at level 14. Also, whenever you use divine smite you can change the damage type to force or psychic. 

Ancient Edict

Choose a target within sight, as an action you may attempt to temporarily weaken them. The enemy must make a Wisdom saving throw of 8 + Charisma modifier + proficiency bonus to not be affected by this ability. On a failed save, the target will have disadvantage on all rolls until the end of their next turn. You can cast Hideous Laughter at will, without expending a spell slot.

Oath Spells

You gain oath spells at the paladin levels listed.
