Curse for good and evil

If the curse is for the good then the person in sight gets an advantage in attack rolls If the curse is for the bad then the person in sight will get a disadvantage in attack rolls.

If the spell slot is above level 1 then the curse does +1 for good or -1 for bad for damage rolls.

Make conditions for the good and bad (ex: give 15 gold to a person who needs it and then your bad curse will be lifted)or(steal at all then the good curse will be gone)

Succeed always but make people do a wisdom saving throw for not taking the curse to get above the save DC of caster.
