Embrace Chaos.

Level 3: Wild Magic Surge

Casting a non-cantrip spell or when 1 is rolled on one of the bardic inspiration dice, wild surge activates.
Roll a d20, if the die lands on 1, roll on the Wild Magic Surge table to manifest a random magic effect.
If that effect is a spell that normally requires concentration, it doesn't require concentration in this case.

 

Level 3: Mean Words

You learn to use your wit to distract, confuse, and otherwise sap the confidence and competence of others. When a creature that you can see within 60 feet of yourself makes a damage roll or succeeds on an ability check or attack roll, you can take a Reaction to expend one use of your Bardic Inspiration; roll your Bardic Inspiration die, and subtract the number rolled from the creature’s roll, reducing the damage or potentially turning the success into a failure.

Level 6: Chaotic Menace

When you roll a intimidation skill check, you may give yourself advantage on that roll.
If one of the dice lands on a 1, Wild Magic activates and an effect manifests from the Wild Magic Table.

Muses Wild Expanse

With a bonus action, you may expend two bardic inspiration's to extend a die to three allies.
You can roll on the Wild Magic Table to regain a bardic inspiration charge.
