Traits

Dying Burst. When the clown drops to 0 hit points, it pops like a balloon, releasing a splash of putrid, corrosive ichor. Each creature within 5 feet of the clown when it bursts must make a DC 12 Dexterity saving throw, taking 10 (3d6) acid damage on a failed save, or half as much damage on a successful one.

Squeakers. The clown wears shoes that squeak when it walks. The squeaking can be heard out to a range of 30 feet. The squeaking is silenced while the clown's Phantasmal Form is in effect.

Spellcasting

Spellcasting. The clown casts one of the following spells, requiring no material components and using Charisma as the spellcasting ability:

At will: friends, mage hand, prestidigitation

1/day each: mirror image, spider climb

Actions

Shock. Melee Spell Attack: +5 to hit, reach 5 ft., one target. Hit:17 (4d6 + 3) lightning damage.

Ray Gun. Ranged Spell Attack: +5 to hit, range 120 ft., one creature. Hit:7 (2d6) psychic damage, and if the target is a Humanoid with an Intelligence score of 3 or higher, it must make a DC 12 Wisdom saving throw. On a failed save, the target perceives everything it sees or hears as hilariously funny and is incapacitated for 1 minute. The target can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.

Bonus Actions

Phantasmal Form (3/Day). The clown veils itself and everything it is wearing and carrying in an illusion that makes it look like some other creature of its size or smaller (such as a child) or an object small enough to fit in the clown's space (such as a floating balloon). Maintaining this effect requires the clown's concentration (as if concentrating on a spell), and the illusion fails to hold up to physical inspection. As an action, a creature that can see the clown's illusory form can make a DC 15 Wisdom (Insight) check, piercing the illusion and discerning the clown's true form on a success.

Lore

Space clowns are the inhabitants of a Wildspace system known as Clownspace. The humans who once inhabited the system's three ring-shaped worlds placed their faith in a god of revelry. Their worship ceremonies were centered on festivals and frivolity. Over time, the people's happiness hinged on the ever-increasing consumption of an elixir called Thrill Joy. Only after they became addicted did they discover that the priests of their faith had distilled the elixir from demonic ichor and the nectar…
