Nailhead

A NailHead is an enemy that spawns during a Solar Eclipse event in Hardmode.

It attacks by shooting nails in 8 directions (all symmetric so every 45 degrees) and walking into the player. It may drop the Nail gun and some nails after his death.

Trivia

 * NailHead is a reference to the character Pinhead from the 1987 film Hellraiser.
