Clown

The Clown is a rare enemy that sometimes appears during Blood Moons on Hardmode. The smiley bomb it throws will destroy nearby blocks when it goes off, like a normal Bomb; this makes the Clowns a serious hazard to any structures. Ranged weapons are the most useful form of attack against clowns as they will explode when killed. You can use them to shoot the clown's bombs out of the air as well. Once you have defeated at least one Clown the Clothier will start selling the clown costume. The most common ways to defend against these enemies is to either:
 * Barricade your house with Dungeon Bricks or raw hardmode ores, which are impervious to bombs.
 * Build your house underground or hide there until the night is over, so that Clowns have no chance to spawn.
 * Travel a fair distance away from any structures (Bombs exploding would not matter in non-edited terrain).
 * Build your house in the sky, so the Clown and his Bombs cannot reach it.
 * Put moats with Lava on either side of your base. Optionally you can install active/inactive stone drawbridges to make it easier for you to access your house.
 * With enough investment, a buffer of chests or storage items planted on tiles will offer complete protection against all explosives. See Storage Items.
