College of the Unspoken

The College of the Unspoken is a bardic tradition that caters to those unable to sow words of their own. The inability to speak proves difficult for a bard, as many teachings rely on our words to perform. Muteness is an invisible disability and many turn a blind eye to it, but the Unspoken use their own ways to prove their worth. 

Many spells are removed from your arsenal, but that's made up with fewer, but more powerful spells.
The language of light persuades all.

Sigil of Song: Caesura, Reaction

Also at 4th level, you learn how to use your Sigils to stun others. When a creature that you can see within 60 feet of you makes an attack roll, an ability check, or a damage roll, you can use your Sigil of Song: Caesura. You can choose to use this feature after the creature makes its roll, but before the DM determines whether the attack roll or ability check succeeds or fails, or before the creature deals its damage. The creature is immune if it can’t sense you or is immune to stun.

Skillful Sigils

At 14th level, when you make an ability check, you can use a Sigil of Song to boost the result. Roll the equivalent of a Bardic Inspiration die, and add the number to your ability check.

 

Mute Proficiency

When you join the College of the Unspoken at 3rd level, you gain greater proficiency with one skill of your choice. (+2 [Skill Choice])
