Sound

The ability to absorb, amplify, and launch sounds and soundwaves. The louder the soundwaves, the more energy it requires. Attacking with sound is risky as it has the potential to easily bring harm to not only your target, but to yourself and your allies.

Ranking
STARTER - You are capable of partially  absorbing sound, allowing you to make things somewhat quieter. You are then able to expel that absorbed sound, if you so choose. This effectively allows you to record and then play back a sound once.

BEGINNER - You are now capable of absorbing and playing back a sound at its full volume, which you can now use to effectively make your movement silent. You are also now able to produce small sonic waves, capable of disorienting a target if they are close enough to the ear.

NOVICE - The soundwaves you create are now capable of going past 100 decibels, and are able to crack or even shatter nearby glass. These soundwaves are also capable of temporarily ringing the ears of anyone close enough. You are also now capable of amplifying your own voice or sounds you have absorbed.

INTERMEDIATE - Your soundwaves are now able to surpass 130 DB, crossing the pain threshold and cause pain to the ears of anyone in their way. These soundwaves can also be focused, creating effective bursts of sound capable of partially going through surfaces, but some of the sound is lost and  bounces back somewhat.. This can also effectively be used as a sonar.

ADVANCED - Holy shit, your soundwaves are capable of surpassing 150 DB, the volume at which someone's eardrums begin to rupture. At this point, your soundwaves are also powerful enough to knock someone down. You are also capable of launching yourself upwards by creating a large sonic blast under you.

MASTER - The soundwaves you can produce have reached their absolute maximum volume at 200 decibels, surpassing even an LRAD in volume and rivaling a sonic boom. You are also able to create what many Sound users like to call “echo chambers”, where they surround a target with multiple sonic blasts, which keep on ricocheting off of one another in that area, capable of causing immense damage to whatever and whoever is in it if these blasts are loud enough. This takes an extreme amount of energy to create and maintain, though, and can only last a few seconds at your absolute best.
