Skyware Chest

The Skyware Chest is a storage item found only on Floating Islands.

Loot
The rare item in a Floating Island chest is more deterministic than other random chests. The first generated chest will have the first item on the rare item list, the second will have the second item and the third will have the third item. All floating island houses past the first three will then have a random rare item from the list.

Aside from this rare item and (sometimes?) a Sky Mill, Floating Island chests have the same random loot as surface chests.
