The Nailhead is a Hardmode, post-Plantera enemy found only during the Solar Eclipse event. In addition to dealing high contact damage, the Nailhead has a 1/3 (33.33%) chance to fire three to five Nails in a spread when attacked. He has significantly more health than most other Solar Eclipse enemies and has a high resistance to knockback.

He is one of the few entities that can be detected by the Lifeform Analyzer or its upgrades. The Nailhead requires 25 kills to be awarded completion of his Bestiary entry and corresponding banner, as opposed to the usual 50 kills.


  • There is a half-second cooldown between firing Nails.[1]


  • Despite having high health and dealing high damage, it moves slower than any other Solar Eclipse enemy, leaving it vulnerable to multiple attacks.
  • Due to the high contact damage, it is risky to fight the Nailhead at close range.
  • In Expert and especially Master Mode, the Nails become nearly as deadly as making contact with the Nailhead. It is crucial to deal damage from a distance, preferably from out of the line of fire.


  • The Nailhead is a reference to the character Pinhead from the 1987 British supernatural horror movie Hellraiser.[2]
  • The BestiaryBestiary entry for the Nailhead: "An intelligent being who seeks out souls to steal, utilizing nails from his own body both as a weapon and as defensive measures."
