The number of cursed energy you possess is based on your class, some classes use a modifier that being charisma or wisdom (Player’s choice)

Your cursed energy DC is 8 + user cursed energy ability modifier + proficiency bonus.

Sound Amplification
Starting at 1st level, you gain proficiency in Performance and one instrument of your choice. While holding an instrument you are proficient in, you can spend 1 CE as an action to play it and launch a Sound Blast at a target within 30 feet. Make a ranged Cursed Energy attack roll, on a hit you deal 2d10 thunder damage and if the target is a creature, it must succeed on a Strength saving throw or be pushed back 10 feet. This technique’s damage increases to 3d10 at 6th level, 4d10 at 11th level, and 6d10 at 18th level.

At 6th level, you have learned to apply your Sound Blast to an area. As an action for 5 cursed energy, you can launch a Sound Wave in a 15 feet cone. All creatures within range must make a Constitution saving throw or take your Sound Blast damage + additional d10s equal to your proficiency bonus and be pushed back 20 feet and deafened until the end of their next turn on a failed save or half as much damage on a successful save.

The range of your Sound Blast now increases to 60 feet. The range of your Sound Wave increases to 30 feet at 11th level.
