As two actions, you curse up to two creatures you can touch or see within 10 meters and within 5 meters of each other. Each creature must make a Will saving throw.
On a failure, whenever a creature makes an attack roll, ability check, or a saving throw before the spell ends, it rolls with disadvantage.
You can target two additional creatures for each additional mana expended. The creatures must be within 5 meters of each other when you target them.
