Terraria Wiki → Solar Eclipse
It can occur during the day after entering Hardmode and killing one of the mechanical bosses. The variety of monsters will increase depending on the bosses you kill.
- If the Goblin Army attacks during a Solar Eclipse, Solar Eclipse mobs will not spawn.
- The chance of appearing instead of a normal day is 4% (1:25).
- The chance of appearing on a normal day after a blood moon increases to 9.72% (7:72).
- The chance of a Solar Eclipse appearing is slightly increased when killing Hardmode bosses.
- You can start an eclipse yourself using a solar cooker.
- A solar eclipse can also occur immediately after the setting of a blood moon or pumpkin moon.
- An eclipse can begin simultaneously with other events that are not time-dependent, such as a slug storm, a goblin invasion, a pirate invasion, or Martian madness.
- A water candle and a battle potion increase the monster spawn rate even more. This is great for speeding up the acquisition of desired items.
- A solar eclipse lasts from sunrise to sunset, lasting one solar day (15 minutes). During this event, monsters exhibit extremely high movement speed and powerful attacks.
- In case of a solar eclipse, it's essential to have the most powerful weapons and armor at your disposal, as well as a well-fortified home, on hand. If you're unsure of your abilities, it's recommended to wait it out in a safe location, such as floating islands. A lava trap and/or dart trap are also recommended.
- If you are not in the line of sight of monsters, they will attack NPCs.
- Cyborg only sells Type IV missiles during the eclipse period.
- During an eclipse in the ocean (and possibly other biomes), the spawn rate of mobs increases by 2 times, just like during a blood moon.
- The remaining monsters in surface biomes disappear (except for the ocean) and do not appear until the eclipse ends.
- A solar eclipse is much darker than an ordinary night, but in real life it is quite the opposite.
- If you place a water candle during a blood moon and then a solar eclipse occurs, the duration of the eclipse increases (possibly a bug in version 1.2.1.1).
- Like the Pumpkin Moon, the Solar Eclipse can be seen in the main menu.
- On a sextant, the moon will appear as red as it does during a blood moon.
- You can wait out a solar eclipse in a dungeon or in hell, where it does not occur.
