Deadly Sphere

Deadly Spheres are Hardmode enemies that spawn during the Solar Eclipse event, only after Plantera has been defeated. They fly randomly in the direction of the player until close, at which point they rapidly charge and attempt to remain on top of the player.

Tips

 * Since they cannot get close to the player if blocks are in their way, blocking them off is enough to avoid taking damage from them.
 * Due to the Deadly Spheres' small size, minions and homing weapons are most effective.
 * Deadly Spheres have one of the highest defense ratings out of any enemy in the game, making weapons that deal large amounts of damage particularly useful.
 * The Morning Star does full damage to the deadly sphere, bypassing all of its defense (although this may be a bug).

Trivia

 * Deadly Spheres are a reference to the 1979 American science fantasy horror film .
 * With 80 defense, it has the third highest defense of all non-boss, non-invincible enemies, topped only by the Sharkron and the Dungeon Guardian.
 * The Deadly Sphere has an unused form in the files.
