Politician

Why bother lifting a finger when a word will suffice? The most subtle blade is the one you don’t hold.

Serpent's Tongue

You gain proficiency in your choice of Deception, Intimidation, Performance, or Persuasion. In addition, you gain a bonus to your Charisma skill checks equal to your Dexterity modifier (min: 1).

Incitement

With words, you can inflame tensions, sowing mistrust and doubt in others. As a bonus action, you can make a Charisma (Persuasion) check against a creature that can see or hear you within 60 feet, contested by the target’s Wisdom (Insight). The target makes this check with advantage if you or your companions are currently fighting it. On a success, you can modify the target’s relationships, making it hostile or friendly to another creature or group of creatures for one hour. This effect ends immediately if you or your companions do anything harmful to it.

Backtrack

Ignore what everyone else’s notes say – what you speak is the truth! As an action, you can make a Charisma (Deception) check, contested by a creature’s Wisdom (Insight) check. This check can be made against any number of creatures that can hear you and share a language with you. In addition, you make this check with advantage if it involves a campaign promise. On a success, you redefine what you’ve said, reshaping peoples’ memories to forget what was previously said.

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

That's Politics!

A backstab can be just as effective for a statesman as it is on the battlefield. Creatures that are friendly to you take 2d6 additional damage from your Sneak Attack. In addition, creatures affected by your Incitement feature are charmed by you for the duration.

Et Tu, Brutus?

When you use your Sneak Attack feature, any number of creatures within 5 feet of your target can make a melee weapon attack against the same target.

If it is the Ides of March, you have unlimited uses of this feature. Otherwise, once you use this feature, you cannot use it again until you finish a long rest.
