Chord of Clashing Fortunes

A single Chord rings out, audible up to 100 feet away.  To some, the chord is a thing of beauty, driving them to greater efforts. To others it is a cacophony of discordant tones that echo through their minds as a constant distraction.

Up to four creatures of your choice in a 30 foot cube within range that can hear fall under the effect of either the Bane or Bless spell.  For each target, choose one of the following effects:
Bless - Whenever a creatures of your choice makes an attack roll or a saving throw before the spell ends, the target rolls a d4 and Adds the number rolled to the attack roll or saving throw.
Bane  -  Creatures of your choice that you can see within range must make Charisma saving throws. Upon a Success, the discordant chord is ignored. On a Failure, whenever the target makes an attack roll or a saving throw before the spell ends, the target rolls a d4 and Subtracts the number rolled to the attack roll or saving throw.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, you can target one additional creature for each slot level above 3rd.
