Fallen Star

Fallen Stars are items that randomly fall from the sky at night and disappear at dawn (4:30 AM). They can be used to craft a Mana Crystal, which permanently increases a player's Mana capacity by 20 points. They are also used in a variety of crafting recipes, and as ammunition for the Star Cannon. Fallen Stars can be stored in ammo slots.

For each game tick (1/60 of a real-world second), the chance of a Fallen Star is 2/1,600 in small worlds, 3/1,600 in medium worlds, and 4/1,600 in large worlds. The average number of Fallen Stars per night is approximately 40.5 in a small world, 60.75 in a medium world, and 81 in a large world.

Fallen Stars emit light while on the ground, making them easy to spot at night. They cannot be placed by the player as permanent light sources, but can be combined with a bottle to craft the Star in a Bottle. They will disappear if dropped by a player during the day, but can remain in a player's inventory or a storage object (such as a chest) indefinitely.

If a Fallen Star hits an enemy on its way down (a rare occurrence), it deals 1,000 damage. They do not damage players.

Tips
Traveling a far distance a few minutes prior to dawn will allow the player to collect the Fallen Stars, easily netting a large supply.
 * A simple method for harvesting Fallen Stars is to construct long straight sections of ground to run along at night. A skybridge also works well, though sky bridges have the disadvantage of catching meteorites and reducing the amount of Meteorite ore the player can collect.
 * To pass Fallen Stars to a friend at day time, transfer it using a chest, since throwing it directly (no matter what) will make it vanish during the day.
 * If the player's inventory is full, a Fallen Star can be moved to the Ammo slot for one extra space, if one ammo slot is empty.
 * Fallen Stars will hit Floating Islands if the Island is in the path of the Star, so if there is an area where Fallen Stars never seem to fall or rarely do, there is a possibility that a Floating Island is above that area.
 * When constructing a star farm, the platform to catch them should be placed at the bottom of space. This seems to be the lowest spot for stars to spawn and allows the platform to catch every all of them including the lower ones.
