Terraria: Bosses

List of Summoning Items and Crafting Recipes

This is a comprehensive list of all boss summoning items and how to craft them, and it's intended to be used as a reference. The list includes simple instructions on where to get each ingredient. Some bosses have linked strategy guides in order to help players prepare for the fight. For more detailed info on bosses, see the main Bosses of Terraria Guide.

Boss: Duke Fishron (PC-only)

Summoning Item: Truffle Worm
How to get Truffle Worm:

• Underground Mushroom Biome - the Truffle Worm will spawn randomly, at a very low chance. Look to youtube for videos on farming masses of these. Use a Bug Net bought from the Merchant. Monsters only spawn off-screen, so stand next to the biome and kill other monsters as they come. Watch for the worm, then nab it with your net!

Notes: Use this as bait while fishing in the Ocean Biome on either side of the map. Make sure it's the bait that comes first in your inventory (top-left to bottom right). Cast your fishing pole, and Fishron will be summoned. Good luck, and don't leave the Ocean biome!

---

Boss: Lunatic Cultist (PC-only)

Kill him to initiate the Lunar Events and collect Solar/Vortex/Nebula/Stardust Fragments. When all 4 pillars are defeated, Moon Lord will spawn on top of the player. Be prepared for a fight, the Cultist is a genuine boss and challenging to newcomers.

Hard Mode Invasion Event Summoning

Invasions have mini-bosses of sorts, so these are worth listing here despite them not being bosses in the strictest sense. Here are what you need to start the game's Invasion Events.

Event: Pirate Invasion (Flying Dutchman)

Summoning Item: Pirate Map

Notes: These can be dropped by any monster in the Ocean Biome during Hard Mode. 1% chance, so set up to farm! The Pirate Invasion is worth farming as the pirates may drop the discount card and lucky coin, both of which have an impact on you financially - making monsters drop more coins, while also reducing prices by 20%.

---

Event: Martian Madness (Martian Saucer)

Summoning Item: None
Materials to Craft:

Notes: Head to the outer third of your world. If you build uptward toward space, it's very likely one will spawn. Hang in the area and move about until you meet a probe, which will scan you. Let it live (do don't have any summon minions out), and the Martian Madness will ensue!

---

Event: Pumpkin Moon (Mourning Wood/Pumpking)

Summoning Item: Pumpkin Moon Medallion

---

Event: Lunar Events (Nebula/Stardust/Vortex/Solar Pillars)

Summoning Item: None

Notes: Kill the Lunatic Cultist after having defeated Golem on PC. The event can be restarted the following morning if Moon Lord kills you, as the Cultists will respawn. You can summon Moon Lord directly once you've saved up Solar/Nebula fragments etc. after having done this event a few times.
