Bare Resolve

You curse one creature you can see within range. For the duration, the target cannot add its proficiency bonus, ability modifiers, or any other bonuses to its saving throws. It still applies penalties and negative modifiers.

At Higher Levels. When you cast this spell using a spell slot of 5th level or higher, you can target one additional creature for each slot level above 4th. The creatures must be within 30 feet of each other.
