I’ve spent hundreds of hours playing through Terraria playthroughs over the last decade, and few events feel as exciting (or frustrating) as the solar eclipse. My first run-in with the event was total luck, spawning randomly right after I beat the Twins, and I walked away with my first Broken Hero Sword to craft the Terra Blade. But when I tried to trigger the event again on a later playthrough to farm more rare drops, I waited three whole in-game weeks with no luck. That’s when I dug into all the reliable ways how to summon solar eclipse in Terraria, no random luck required.
How to Summon Solar Eclipse in Terraria: Pre-Requisites First
You can’t trigger a solar eclipse in pre-Hardmode, no matter what tricks you try. The event is locked behind two key progression milestones that you have to hit first, no exceptions. The first is Hardmode activation (defeat the Wall of Flesh) in the Underworld. This unlocks all late-game content, including rare events like the solar eclipse.
The second non-negotiable requirement is at least one mechanical boss defeated. It doesn’t matter if you beat The Destroyer, Skeletron Prime, or the Twins first – once any of the three is dead, solar eclipses become eligible to spawn. If you try to summon the event before hitting these two milestones, nothing will happen, even if you have a Solar Tablet in your inventory. If you’re still working your way through early Hardmode, focus on beating those mechanical bosses first before you worry about how to summon solar eclipse in Terraria.
Once you meet these requirements, there’s a 4% chance a solar eclipse will spawn automatically every in-game sunrise. That might not sound too low, but I’ve gone 20+ in-game days without seeing a spawn on multiple playthroughs, so relying on natural spawns is only a good idea if you’re not in a hurry to farm specific drops.
Crafting and Using the Solar Tablet for Instant Summons
If you don’t want to wait around for random chance, the Solar Tablet is your best bet to trigger the event whenever you want. This consumable item lets you summon a solar eclipse on demand, as long as you use it correctly. You can find full Solar Tablets in chests scattered around the Jungle Temple, but most players will craft them from fragments instead, since drops from temple enemies are far more consistent than lucky chest spawns.
To craft a Solar Tablet, you’ll need 8 Solar Tablet Fragments and access to a Mythril or Orichalcum Anvil. The recipe is automatically unlocked once you pick up your first fragment, so you don’t need to find a special schematic to make it. Each tablet is single-use, so if you want to run the event multiple times, you’ll need to craft multiple tablets.
The biggest mistake new players make with the Solar Tablet is using it at the wrong time. You can only use the item during in-game daytime, between 4:30 AM and 7:29 PM. If you use it at any point after the sun sets, the tablet will be consumed and no event will spawn. I made this mistake my first time trying to summon the event, so don’t throw away a perfectly good tablet by using it after dark. If you use it during the day, the eclipse will start immediately, and last until the in-game sun sets for the night.
Reliable Ways to Farm Solar Tablet Fragments Fast
Now that you know how to summon solar eclipse in Terraria with a Solar Tablet, you’ll need to farm enough fragments to make as many as you need. Solar Tablet Fragments only drop from enemies inside the Jungle Temple, so you’ll need to have defeated Plantera first to get access to the temple doors. Once you’re inside, there are a few simple tricks you can use to farm dozens of fragments in a single hour, enough to summon the solar eclipse as many times as you want.
- Farm Lihzahrd enemies in the Jungle Temple: Every Lihzahrd and Flying Snake has a 2% drop rate for Solar Tablet Fragments, so running through the temple multiple times will net you dozens of fragments in an hour. You don’t have to fight the Golem to farm fragments, so you can skip that boss until you’re ready if you want.
- Use a Water Candle and Battle Potion combo: These items boost enemy spawn rates by 50% and 20% respectively, cutting down your farm time significantly. Just make sure you’re well-equipped to handle more spawning enemies at once, since Lihzahrds hit very hard in Hardmode.
- Set up a farm spot near the temple entrance: Build a small enclosed area with platforms and spawn proof all surrounding areas outside the temple, so all enemy spawns are focused on Lihzards and Flying Snakes right in front of you. This cuts down on time you spend running through the temple looking for enemies.
This farm works every time, and it’s the most consistent way to get all the materials you need for how to summon solar eclipse in Terraria whenever you want. If you’re lucky, you might also find full Solar Tablets in Lihzahrd chests as you explore the temple. Each chest has a 10% chance to contain one tablet, so it’s worth opening every chest you find even if you’re mostly farming fragments. Just be careful of traps inside the temple, as most chests are wired to trigger dart traps or boulders if you don’t disarm them first.
What to Expect During a Solar Eclipse Event
Once you’ve got the process down for how to summon solar eclipse in Terraria, you’ll want to know what to expect when the event starts. Once you trigger the event, the entire screen will dim slightly even during the day, and unique, high-damage enemies will start spawning anywhere on the surface, even near your base. Most of these enemies have special abilities like wall-penetrating attacks, fast movement, or high health pools, so you’ll want to be prepared before you summon the event. I recommend wearing at least Hallowed Armor or equivalent before you start the eclipse, to avoid getting one-shot by surprise enemies.
The main reason most players farm solar eclipses is for the Broken Hero Sword, a rare crafting material required to make the Terra Blade, one of the strongest swords in pre-Moon Lord content. The Broken Hero Sword drops from Mothron, a mini-boss that spawns only during solar eclipses, with a 25% drop rate per kill. Other rare drops include Mothron Wings, the Vampire Frog Staff, and the Moon Stone, which boosts all your stats during nighttime.
There’s one more important rule to remember during the event: don’t sleep in a bed to skip time. If you sleep through the day, the solar eclipse will end immediately, and you’ll waste your Solar Tablet for no reward. I learned this the hard way when I got bored halfway through an event and tried to skip to nighttime to fight a different boss, only to lose all my progress on farming Mothron drops. If you want to end the event early, the only reliable way is to use an item that changes the time to night, though I don’t recommend it unless you’re in a real hurry.
At the end of the day, how to summon solar eclipse in Terraria doesn’t have to be a matter of pure luck if you know the right steps. Whether you’re waiting for a random spawn after beating your first mechanical boss, or farming fragments to craft Solar Tablets on demand, you can trigger the event whenever you need to farm rare drops or fight the unique enemies it offers. Take the time to farm enough fragments for a few runs at a time, and you’ll have all the Broken Hero Swords and rare loot you need in no time.
