The Stone Skull (スピンヘッド, Spin Head in the Japanese version) is a big spinning skull found in various locations within the Reverse Castle of Castlevania: Symphony of the Night. It is invincible and as such cannot be destroyed by any means.
- There are two variations of Stone Skulls in Symphony of the Night, one resembling a yellow human-like giant skull, and other which resembles that of a bovine. Both variations behave the same upon attack and move in the same patterns, the only difference being, aside from their appearance, the locations where they are found.
- Interestingly enough, if a Stone Skull is hit with the Mourneblade or the Soul Steal spell, it will give back health to the player. Additionally, using the spell of the Alucard Shield combined with the Shield Rod or Mablung Sword will grant Alucard +8 HP and +1 Heart per hit, which could slowly refill his health and hearts to full.
