College of Mime and Acting (COMA) 

Silence is Golden

When you join the COMA, you have learned sign language, a mix of hand motions that allows you to communicate to anyone in any language that you know. Any creature that knows that language can understand your hand motions. In addition, you can use sign language when using spells and items that would normally require speech.

Copy Cat

Starting at 3rd level, you can use your reaction and expend one of your bardic inspirations to copy a feature you have seen. This can only be used on features that are activated and not passive features. You can retain a number of features up to your Charisma Modifier. You can use these features as your own as long as you retain them. You can replace a feature with another one whenever you learn a new one. When you replace one, the feature is unusable until you learn it again. 

Mime Time

At 6th level, as an action, you create an Invisible object of force springs into existence at a point you choose within 5ft of you. The object appears in any form you choose, a rope, a door, a box etc. It can be free floating or Resting on a solid surface. You can be no larger then a 5ft cube. In any form, it lasts a number of rounds equal to your Charisma Modifier. If the object cuts through a creature's space when it appears, the creature is pushed to one side of the object (your choice which side).

Nothing can physically pass through the object. It is immune to all damage and can't be dispelled by Dispel Magic. A Disintegrate spell destroys the object instantly, however.

Mirror

At 14th level, as an action, you target a humanoid that you have spent at least 10 days with. You polymorph into a perfect duplicate able to mimic all aspects of that indivual. This lasts until dispelled by magical means or you dismiss it as a bonus action. Additionally, while in this form, you have access to all special features, traits, sights, speeds and attack capabilities as the creature. If the creature has character levels, you have access to all class features up to a level equal to your proficiency bonus + your Charisma Modifier.  You are unable to use this feature on humonoids that have a CR higher then your level.

Once you use this feature you cant do so again until you finish a long rest.
