Rockstar

Maestro's who follow the rockstar genre bring their music to a whole new volume, blasting their foes away with ruthless thunderous force.

High Volume

Beginning when you select this subclass at 3rd level, you gain the Thunder affinity, and learn 2 Thunder affinity techniques of your choice. At 6th, 10th, and 14th level, you can learn an additional Thunder affinity technique. These techniques do not count against the number of techniques you can learn. 

You have learned how to tune your thunder technique to cause that much more damage. When you cast a technique that deals thunder damage, add your Charisma modifier to that damage. In addition, you learn the Forceful Refrain Maestro Movement.

Forceful Refrain

When you or a friendly creature within your symphony hits a creature with an attack, they may force the creature to make a Strength Saving throw against your Special save DC. On a failure, the creature is pushed 10 feet away from their attacker.

Beat - Musical Strike

At 3rd level, your music guides the flow of battle for your allies. As a bonus action you may spend 1 beat point to allow an ally within 30 feet of you who can see or hear you to cast a base technique with a casting time of 1 action as a reaction.

Booming Sound

At 6th level, your symphony amplifies your techniques, causing a great blast whenever you cast one. Whenever you cast a technique while concentrating on your symphony, you may cause a burst of thunder within a 15-foot radius of you, forcing all creatures within range to make a Constitution saving throw. On a failed save they take 3d6 thunder damage, plus an additional 1d6 thunder damage for each rank of the technique. You can use this feature a number of times equal to your Charisma modifier per long rest.

Accelerando - Roaring Intro

By 10th level, you can infuse some of the thunderous power of your music into your allies. Allies within 30 feet of you who can see or hear you deal additional thunder damage equal to your Charisma modifier on their first damage roll made before the end of their first turn after rolling initiative.

Max Noise

At 14th level, you can unleash all restraint and let your techniques blast away at full volume. When you begin your symphony you can choose to activate this feature, gaining the following benefit and detriment for a minute:

When you cast a technique that deals thunder damage, you deal maximum damage with that spell.

When you cast a technique you must make a concentration save with a DC of 10 + the technique's rank. If you fail the concentration save you also become stunned until the start of your next turn.

Once you use this feature you can't use it again until you've completed a long rest.
