Crout's Melancholia

You play a melancholic tune turning the nightmares of a creature you can see within range into illusory manifestation, summoning a nightmare spirit. The target must make a Wisdom saving throw. On a failed save, the target becomes frightened for the duration, while frightened this way the creature is grappled . At the end of each of the target's turns before the spell ends, the target can repeat the save to end the condition. When you cast the spell, you can make a melee spell attack against a creature within 10 feet of the spirit. On a hit, the target takes psychic damage equal to 3d10 + your spellcasting ability modifier.

As a bonus action on your turn, you can move the spirit up to 20 feet and repeat the attack against a creature within 10 feet of it.

At Higher Levels. When you cast this spell using a spell slot of 5th level or higher, the damage increases by 1d10 for each slot level above 4th .
