Exhaust Willpower

You attempt to weaken the will of an enemy by drawing upon existing emotions. It must succeed on an Intelligence saving throw or become tortured by their emotions for the duration. The spell automatically fails if the creature is immune to Psychic damage or has the enemy has an Intelligence score lower than 3. While the target is affected, they must make Intelligence saving throws at the start of their turn. On a success, the spell is dispelled. On a fail, the target suffers from the following effects: Their Constitution score is lowered by 2 for every failed saving throw, they have disadvantage on attack rolls, and they are vulnerable to Psychic damage. If the enemy's Constitution score becomes lower than 6, you may use your reaction on your turn or their turn to command them. It will attempt to follow through with that command when you use the reaction and on their turn until a new command is issued, their Constitution score becomes higher than 5, or upon the spell ending. At Higher Levels: When you cast this spell using a spell slot of 4nd level or higher, you can affect one additional creature for each slot level above 3rd. The creatures must be within 30 feet of each other when you target them.
