Bane's Blessing

A hybrid spell of Bane and Bless.

One creature of your choice that you can see within range must make a CHA saving throw. On a failed save, they will be affected with Bane, whenever the target that fails this save makes an attack roll or a saving throw before the spell ends, the target must subtract 1d4 from the attack roll or save.

If the first creature is successfully affected with Bane, you may choose a different creature visible in range to be Blessed, whenever the Blessed target that makes an attack roll or a saving throw before the spell ends, the target adds 1d4 from the attack roll or save. The second creature cannot be Blessed if the first succeeded on the CHA saving throw.

Using a Higher-Level Spell Slot. You can repeat the spell on new targets for each spell slot level above 1.
