Solar Eclipse

Sun and moon as seen during the event

A Solar Eclipse is a Hardmode event that occurs rarely after at least one Mechanical Boss has been defeated. A Solar Eclipse has a 1/25 (4%) chance of occurring on any particular day (for comparison, the Blood Moon has a 1/10, or 10% chance, each night).

During a Solar Eclipse, unique and difficult enemies spawn at very high rates, even near NPCs. The event lasts for one entire day, from sunrise to sunset, regardless of the number of enemies that have been killed. The moon is visible in front of the sun, causing the ambient light level to drop to near-nighttime levels.

A Solar Eclipse is announced at the beginning of a day with the message, "A solar eclipse is happening!" The event only affects the surface layer, and can be avoided by burrowing well into the underground layer or below.

  • It is possible for other events to occur at the same time as a Solar Eclipse, such as a Goblin Invasion. Other events may cancel Solar Eclipse enemy spawns.
  • Swamp Things seem to be the most common Solar Eclipse enemies to spawn, followed by Frankensteins, Reapers, and Vampires, with Eyezor being the least common.
  • A Solar Eclipse can occur the day before or after a Blood Moon. One will not affect the chances of the other following, and the same event can follow the next day or night as well.
  • Every enemy but the Reapers and Vampires use standard Fighter AI, and even share the same jump range as basic Zombies.
  • Unlike a blood moon, it has only its own enemies, where blood moons have most regular enemies ( with the exception of the groom and clowns). The only exception is in corruption, Crimson, and the Ocean.
