Planetoid

Planetoids are 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, and the size of the planetoid scales with the 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 a random type of moss. They will always contain a Life Crystal encased in either Platinum Brick or Gold Brick and will typically contain a cluster of a specific type of gem; however, there is a small chance that a gem cluster will not be generated.

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 pyramid-like structure (comparable to an Enchanted Sword Shrine) constructed of Stone Slabs with Shadewood Lamps on either side.

Jungle Planetoids

A Jungle Planetoid.

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, and can generate with Jungle Trees on top of them.

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. Like Jungle Planetoids, Jungle Trees can generate on top of Beehive Planetoids.

Tips

• Like with Floating Islands, Gravitation Potions are an extremely useful asset in locating Planetoids.
• 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.
  • However, the existence of Beehive Planetoids in the sky can result in Queen Bee spawning if the player is reckless with far-reaching projectiles, as the hive larvae is extremely sensitive and can be broken by stray projectiles that manage to touch it.
• Having a Mushroom Planetoid in your world is also very useful, as it allows Crabulon to be fought before finding the Glowing 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.
