Oath of Truth

You are sworn to protecting and spreading the truth.

Channel Divinity

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

Binding Strike. When you expend a spell slot to smite a creature with your divine smite, you can cause golden chains to surround the creature, causing it to be restrained. A creature restrained by this ability can make an athletics check against your spell save DC to break free. Any creature within 5 feet of the restrained creature may also make an athletics check to free the creature.

Unveil the Truth: When you use your divine sense feature, any creatures you detect must make a wisdom saving throw.  On a failed save, you become aware of its alignment and what it was thinking for the last 10 seconds. In addition, you are aware of any deliberate lie it told within the last 10 seconds.

Oath Spells

You gain oath spells at the paladin levels listed.

Oath of Devotion Spells

Aura of Insight

Starting at 7th level, you and friendly creatures within 10 feet of you gain advantage on insight checks while you are conscious.

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

Bearer of Truth

Beginning at 15th level, you cannot deliberately tell a lie. Creatures within 30 ft. of you are automatically aware of this effect, and are aware that anything you say cannot be a lie. You have advantage on persuasion checks against such creatures.

Aura of Truth

At 20th level, as an action, you can emanate an aura of truth. For 1 minute, bright light shines from you in a 30-foot radius, and dim light shines 30 feet beyond that.

For the duration, you are aware of the thoughts of all creatures within 30 ft. of you, and know when a creature tells a deliberate lie. You also know the answer to any deliberate lie a creature tells.

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