There are multiple bosses to fight in Terraria. Each of these bosses has a unique summoning requirement that you will need to meet if you plan on taking them on and you will if you plan on working through the game. You can choose to face them alone or with a group of friends. This guide will cover how to summon all the bosses in Terraria.

Summoning all bosses in Terraria

There are three types of bosses that you can encounter in Terraria. Pre-hardmode, hardmode and event bosses.

All bosses in Pre-Hard mode

Brain of Cthulhu

You need to use Worm Food or break three Shadow Orbs. You can create Worm Food by finding 30 Vile Powder and 15 Rotten Chunks and taking them to a Demon or Crimson Altar. After creating it, you need to proceed to the Corruption part of the game and consume it. Otherwise it will have no effect and will not summon the boss. Alternatively, you can find all three Shadow Orbs by visiting the Abyss of Corruption levels.

Devourer of worlds

You need to use Worm Food or break three Shadow Orbs. You can create Worm Food by finding 30 Vile Powder and 15 Rotten Chunks and taking them to a Demon or Crimson Altar. After creating it, you need to proceed to the Corruption part of the game and consume it. Otherwise it will have no effect and will not summon the boss. Alternatively, you can find all three Shadow Orbs by visiting the Abyss of Corruption levels.

eye of cthulhu

The only way to summon the Eye of Cthulhu is to use the Eye of Suspicious Gaze. You need six lenses to craft the item, and you must do it on a Demon or Crismon Alter. Alternatively, you can loot the item by looking inside frozen golden chests in the Cavern and Dungeon or ivy chests in the Jungle. Once you have the eye, you must use it at night to summon the Eye of Cthulhu.

slime king

You can only summon the Slime King using the Slime Crown. The only way to craft is by using 20 Gel with a Gold Crown or Platinum Crown and then crafting it at a Demon or Crimson Altar. Once you have the item, you can use it at any time to summon the monster.

Queen bee

There are two methods to summon Queen Bee. The first is to create the Abemination and use it in the jungle biome. To craft the item, you need to have a bottled honey jar, five hives, five honey blocks, and a stinger. After that, you can prepare item by item. Alternatively, you can break the queen bee larva, which you can find inside a Bee Hive in the Jungle biome.

skeleton

Skeletron is how you gain access to every dungeon in the game, so it’s essential. You can summon it by talking to the NPC Old Man at night. Talking to him at this time activates a curse and summons the boss to your location. After defeating Skeletron once, you can summon it again by killing the Clothier, an NPC who sells you toiletries, using the Clothier Voodoo Doll, and it’s night.

wall of meat

You can only summon the Wall of Flesh by throwing a voodoo doll from the guide, the first NPC near you at the start of the game, into the lava. The Guide must be alive at the time you throw it into the burning pit. To find the guide voodoo doll, you can eliminate the voodoo demons in the underworld.

All hardcore bosses

duke fishron

To summon Duke Fishron, you need to find a Truffle Worm in the glowing mushroom biome. So, you just have to capture it using a bug net. Once you have it, and have caught it using that particular net, use it as bait on your fishing rod in the ocean biome.

empress of light

You need to find a Prismatic Lacewing to summon the Empress of Light. Before this creature appears, you must defeat Plantera. After that, you can find a Prismatic Lacewing in the Surface Relic from Dusk to Midnight, and you need to catch it with a Bug Net. You can then free the creature at any time in any biome and kill it to summon the Empress.

Power cells have a chance to drop from lihzahrd creatures and flying snakes found inside temples, or you can find one inside the lihzahrd chest. You must have defeated Plantera first before you can summon the Golem.

For the lunatic cultist to come out, you must first defeat the golem, and then find all four cultists standing at the dungeon entrance to the mysterious tablet. The lunatic cultist will arrive after you kill these four cultists.
