SILVER TONGUED (1ST LEVEL)

Your dealings with the fey have left you with the ability to talk circles around the average mortal. At first level, your proficiency bonus for any charisma (persuasion) check you make is doubled.

In addition, as an action you can attempt to fast talk any creature who can understand a language you can speak. Choose one creature who can hear you within 60 feet. That creature must make a wisdom saving throw (DC of 8 + your proficiency bonus + your charisma modifier) and on a failed save is charmed by you for 1 hour.

While charmed in this way, the creature treats you as if you were an old, dear friend. If you threaten or harm either the creature or any of its allies while it can see or hear you, the creature can make the saving throw again, ending the effect on a success. You can only have one creature charmed this way at any given time. You can voluntarily end the effect on any creature as an action.

After using this action, you must complete a long rest before you can attempt it again. Every time you gain a new grand feature, you can use this feature an additional time before resting, and an additional creature may be affected (two times at and two creatures 7th level, three times and three creatures at 12th level, and four times and four creatures at 18th level).

UNEARTHLY GUILE (7TH LEVEL).

Dealing with the fey constantly has taught you well in the ways of trickery. You’ve learned to mimic the voices of others well, granting you advantage on any Charisma checks that rely on you changing the sound of your voice to mimic another person or creature.

In addition, you can cast the alter self spell once without expending a spell slot. When you cast this spell, you can affect either yourself, one creature within 10 feet of you under the effect of your silver tongued ability, or both. Once you cast this spell, you must finish a short rest or long rest before you can cast it in this way again.

FEY STEP (12TH LEVEL)

You have learned to be as elusive as a fey creature. You learn the spells invisibility, misty step, and dimension door. You can cast each of these spells once without using a spell slot, but if you have the appropriate spell slots, you can cast them as normal through those slots. These spells don’t require verbal or somatic components when cast without using a spell slot.

After casting invisibility or misty step without using a spell slot, you must finish a short or long rest before you can do so again. After casting dimension door without using a spell slot, you must finish a long rest before you can do so again.

MASTER MANIPULATOR (18TH LEVEL)

You have mastered the way of speech and can wrap average people around your finger. You are no longer limited to number of creatures affected by your silver tongued ability, and the duration now lasts for 24 hours. You also regain your uses after a short or long rest instead of a long rest.

After the duration has elapsed, make a contested Charisma (persuasion) check vs the creature’s Wisdom(insight) check. If you succeed, the creature becomes fanatically devoted to you permanently, and considers you an old, dear friend, prioritizing you over other allies. The creature still acts of its own accord but holds your words in very high regard, and will perform almost any course of action you request.

The DM might decide that certain creatures or entities cannot be bewitched by you in this way permanently.

Any creatures permanently enamored with you can, at your discretion, be affected by your unearthly guile whenever you use it, but you can still only affect yourself, one creature under the affect of silver tongued, or both as normal.

You can have a number of creatures devoted to you in this way up to your charisma modifier. If you charm another creature in this way while you already are at your limit, the oldest creature under this effect is no longer affected by this ability. Otherwise, this ability can only be removed by a remove curse, wish spell, or similar other magics
