Clown Priest Stone Vessel

Immutable Form. The vessel is immune to any spell or effect that would alter its form.

Magic Resistance. The vessel has advantage on saving throws against spells and other magical effects.

Magic Weapons. The vessel's weapon attacks are magical.

Multiattack. The vessel makes two slam attacks.

Slam. Melee Weapon Attack: +2 to hit, reach 5 ft., one target. Hit: 1d4 + 3 bludgeoning damage.

Nose Beam.  Spell Attack: the vessel unleashes a targeted beam of light from its ruby nose at any one target it can see. Hit: 1d6 + 3 radiant damage.

Stone Balloon Minion (Recharge 5–6). The vessel uses rubberstone balloons to create a balloon animal minion from conjure animals.

Slow (Recharge 5–6). The vessel targets one or more creatures it can see within 10 feet of it. Each target must make a DC 13 Wisdom saving throw against this magic. On a failed save, a target can't use reactions, its speed is halved, and it can't make more than one attack on its turn. In addition, the target can take either an action or a bonus action on its turn, not both. These effects last for 1 minute. A target can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.

Trick Lapel Flower. Whenever the vessel takes damage from a physical weapon and the attacker is within 5ft., and the vessel rolls a 15 or higher on a d20, deal 1d4 -1 acid damage to the attacker.
