Unruly Cat

A spectral cat appears in an unoccupied space of your choice within range. When the cat appears, all creatures of your choice within 10 feet of the cat must succeed on a WIS saving throw  or be charmed. A charmed creature must use it's turn to move toward the cat and pick it up. When the cat is picked up, it goes into a frenzy, inflicting 3d8 slashing damage. When a creature takes damage from the spectral cat, it must succeed on a CON saving throw or have an allergic reaction to the cat. The allergic reaction causes the creature to have disadvantage on attack rolls, ability checks and saving throws until the end of its next turn

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the damage increases by 1d8 for each spell slot above 2nd.
