Tweaked from 5eYou already know this as 5e Bane — It's Bane stripped down for at-will spam—same Charisma save and d4-subtracted penalty, but it hits one target for only their next roll (no concentration, no three-target spread) and the die grows as you level.
Force a creature to subtract 1d4 from its next attack roll or saving throw on a failed Charisma save.

A target of your choice within range must make a Charisma saving throw. On a failed save, when the target makes their next attack roll or saving throw they must roll a d4 and subtract the number from it. The power then ends.

This power's die increases at higher levels: to a d6 at 5th level, a d8 at 11th level, and a d10 at 17th level.
