Stone Fairy
The Stone Fairy is a Pre-Hardmode fairy which spawns in the Cavern layer. While they have a clear line of sight to a player, they will cause stalactites to rapidly grow on the ceiling above the targeted player, provided that the ceiling is made out of Stone, Ebonstone, Pearlstone, Crimstone, Granite or Marble. After a short duration, these stalactites will fall down, causing damage to any player they hit.
Stone Fairies drop one or two Point Items. In addition, they have a 33% chance of dropping a Blinkroot.
