Planetoid

Planetoids are new structures added by the Calamity Mod that are created in the Space layer during world generation. They are floating spheres of blocks with varying sizes and materials, often containing valuable loot. There are 6 different types of planetoids: the Main Planetoid, Life Crystal Planetoids, Ore Planetoids, Jungle Planetoids, Beehive Planetoids, and Mushroom Planetoids. After defeating the Moon Lord, they will all be filled with Exodium Clusters. Most planetoids are generated within the middle 3rd of the map, although sometimes planetoids can be generated farther out from the center.

Main Planetoid

The Main Planetoid.

The Main Planetoid will always be located in the exact center of the map, above the player's spawn. It is the largest of the planetoids; the size of the planetoid scales with map size. At the center, there will be a structure made out of Stone Slabs, with a "core" composed of lava surrounded by Cinderplate. To the side of the core, there is a small laboratory containing a Heavy Work Bench, various placed bottles and a Chest containing several gardening items.

Life Crystal Planetoids

Life Crystal Planetoids are the smallest and most common of the planetoids, and are made of stone that is covered in moss. They will all contain a Life Crystal encased in either Platinum Brick or Gold Brick, and also have a cluster of a random gemstone.

Ore Planetoids

Ore Planetoids are large planetoids containing streaks of a Pre-Hardmode Ore. The ore will always be the counterpart to one of the Pre-Hardmode ores generated in its world (for instance, if the world generated with Copper, a planetoid would contain Tin). They occasionally have a campfire and a tent on top of them, or a structure similar to an Enchanted Sword Shrine constructed of Stone Slabs with Shadewood Lamps on either side.

Jungle Planetoids are average sized planetoids made of mud and Jungle grass. They always contain a pool of water in the center with an accompanying Water Chest.

Beehive Planetoids

A Beehive Planetoid.

Beehive Planetoids are very similar to Jungle Planetoids, as they are both made of mud and Jungle grass and are around the same size. The Beehive Planetoid, however, will contain a bee hive with some honey and a Queen Bee larva.

Tips

• Building platforms around the Beehive Planetoid can be used as an arena to fight Queen Bee as an alternative to finding and hollowing out a hive in the Underground Jungle.
• Having a Mushroom Planetoid in your world is also very useful, as it allows Crabulon to be fought before finding a Mushroom biome underground and allows the Truffle to be acquired easily.

Trivia

• The Cinderplate in the the center of the Main Planetoid is based off of the core of the Earth.
