Deadly Spheres are Hard Mode enemies that spawn as part of the Solar Eclipse event. They appear initially as just a ball, but once they near the player they sprout spikes and fly into them. Usually, they can move through walls, but not when they are attacking the player.
While they has high defense, these are easily stopped by rapid-firing weapons or the Piranha Gun.
They are incredibly small, and therefore, it's usually very hard to hit them with machine guns unless one uses Chlorophyte Bullets.
- The Deadly Spheres are a reference to the movie Phantasm.
- They emit an electrical cracking sound when damaged.
