Floating Island



A Floating Island is a mass of isolated Forest land found in the sky, generally well above the world's main land mass. Each world will contain at least one Floating Island, up to a possible eight maximum in large worlds. Their location makes them susceptible to Harpies in normal mode, Wyverns in Hardmode, and Arch Wyverns in the console and mobile version's Hardmode. Being at high altitude, players usually experience reduced gravity when navigating them.

Floating Islands are one of two natural floating masses that can generate in a Terraria world, the other being Floating Lakes. Both are similar in their size and placement, and both rest atop Cloud and Rain Cloud blocks with background Cloud Walls.


 * Floating Lakes consist of nothing more than a large body of water resting in Cloud and Rain Cloud blocks. There will generally be relatively few of these in a world.
 * Floating Islands contain little to no water, and instead have Forest land resting in its Cloud blocks, along with a natural structure.

A Floating Island's structure is constructed from Sunplate Block, Disc Wall, and Glass Wall. It will always contain one Skyware Chest along with other random Skyware furniture. Each Skyware Chest contains either a Lucky Horseshoe, Starfury, Shiny Red Balloon, or Sky Mill, along with other typical Forest chest loot. Unique items are chosen at random, with the restriction that all three unique items must be spawned at least once before truly random unique items spawn on any remaining Islands.

Floating Lake
A Floating Lake is a mass of isolated Cloud and Water found in the sky, generally well above the surface. It is a variation of floating islands, and was added in the 1.3.0.1 update. Unlike floating islands, they do not have Sunplate Block structures.

Floating lakes consist of a large body of water atop Cloud and Rain Cloud blocks with background Cloud Walls. The body of water is usually quite large, making it a reasonably good place to fish. Some fish exclusive to the elevation can be fished from these, like the Damselfish. It is rare, but Floating Lakes can contain Water Chests.

Trivia

 * Floating Islands were originally made out of Dirt and Stone Blocks. The house was either made of Gold, Silver or Copper Bricks with a single Gold Chest inside, causing it to resemble a shrine. Grass vines hanging below the island could be used to locate it as projectiles would make noise when destroying them.
 * It is possible for a natural world spawn to be on a floating island.
