How to summon all bosses in Terraria

There are several bosses to fight in Terraria. Each of these bosses has a unique summoning requirement that you must complete if you plan on taking on them, and if you plan on progressing through the entire game. You can choose to compete alone or with a group of friends. In this guide we will tell you how to summon every boss in Terraria.
Summon all bosses in Terraria
There are three types of bosses that you can find in Terraria. Pre-Hardmode, Hardmode, and Event bosses.
All bosses in pre-hard mode
Brain of Cthulhu
You have to use worm food or break three shadow orbs. You can craft Worm Food by finding 30 Vile Powder and 15 Rotten Chunk and taking them to a Demon or Crimson Altar. After crafting it, you must proceed to the corruption part of the game and consume it. Otherwise it has no effect and does not summon the boss. Alternatively, you can find the three shadow orbs by visiting the Chasm levels of corruption.

Eye of Cthulhu
The only way to summon the Eye of Cthulhu is to use the suspicious looking eye. You need six lenses to craft the item and you need to craft it at a Demon or Crismon age. Alternatively, you can loot the item by looking in gold and frozen chests in the cave and dungeon, or in ivy chests in the jungle. Once you have the Eye, you must use it at night to summon the Eye of Cthulhu.
king of slime
You can only summon King of Slime with the Slime Crown. The only way to craft it is to use 20 Gel with a Gold Crown or a Platinum Crown and then craft it at a Demon or Crimson Altar. After 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 Abbemination and use it in the jungle biome. To craft the item, you must have with you a honey jar, five beehives, five blocks of honey, and a stinger. After that, you can prepare item by item. Alternatively, you can break the queen bee larva, which you can find in a beehive in the jungle biome.
skeleton
Skeletron gives you access to all dungeons in the game, so it’s essential. You can summon it by talking to the Old Man NPC at night. Speaking to him at this hour will activate a curse and summon the boss to you. After defeating Skeletron once, you can summon it again by killing the Clothier, an NPC who will sell you cosmetic items using the Clothier Voodoo Doll, and it’s night.
wall of flesh
You can only summon the Wall of Flesh by throwing a voodoo doll of the Fuhrer, the first NPC near you at the start of the game, into lava. The leader must be alive at the time you throw him into the flaming pit. To find the Guide Voodoo Doll, you can turn off Voodoo Demons in The Underworld.
All hardcore bosses
Duke Fishron
To summon Duke Fishron, you need to find a truffle worm in the glowing mushrooms biome. Then all you have to do is catch it with an insect net. Once you have it and caught it with this special net, use it as bait on your fishing rod in the ocean biome.
Empress of Light
You must find a Prismatic Lacewing to summon the Empress of Light. Before this creature spawns, you must defeat Plantera. After that, you can find a Prismatic Lacewing in the Surface Sanctum from dusk to midnight, which you need to capture with an Insect Net. You can then release and kill the creature at any time in any biome to summon the Empress.
golem
The giant golem is only summoned with a Lihzahrd power cell at the Lihzahrd altar, which you can find in the jungle biome. The Power Cells can be dropped from the Lihzahrd and Flying Serpent creatures that are in the temples, or you can find one in the Lihzahrd Chest. You must first defeat Plantera before you can summon the golem.

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