School of BASS

Your connection to your bass has allowed you to turn it and yourself into a deadly weapon. Not only is it a melee weapon, but it will also deal damage to enemies, de-buff them, and buff your friends.

The Bass is a Pact Weapon.

The Bass is a pact weapon, therefore the user can summon it at will and it can not leave 5ft of the owner. Charisma bonus is added along with proficiency. 

Drop D

As an action you can re-tune your BASS to drop D. Can only be applied to "The Bass".

While in drop D, Wild Note will deal (refer to Level Scale) in a 10ft. radius of thunder damage. Any creature affected will make a constitution saving throw against the BASS user's spell casting DC. Upon success, half damage. Upon critical failure, creature is now deafened for 1 minute.

As an action, you tune your BASS to E Standard. This will remove effects of Drop D.
