Oath of the Underhanded

Unlike the Oath of Glory, you'll do anything to win, even if it's fighting dirty.

Inspiring Smite

Aura of trickery

At 7th level, you emit an Aura that increases the movement speed of you and your allies (within thirty feet) by ten feet.

You also gain the ability to use your oath spells (one per level) per day without expending a spell slot. The spell cannot be your divine smite, and at later levels you're capped with using this ability to your first and second spell slots.

Cheeky Defense

When you reach 15th level, you can turn an attack against you or an ally into a strike. When you or a friendly creature within 10 feet of you is hit by an attack you can use your reaction to impose disadvantage by distracting it potentially causing the attack to miss. You can use this ability a number of times equal to your charisma modifier (for a minimum of one), you regain all uses of this ability when you finish a long rest.

Living Legend

At 20th level, you use your fame to give you the following benefits for one minute:

You have advantage on all Charisma based checks, once on your turn you can turn a missed attack into a hit instead, and you you can use your reaction to re-roll a failed save, must use the second roll. You may use this feature again after a long rest or expend a fifth level spell slot.
