Fallen Star

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

For each game tick✅, the chance of a Fallen Star spawning is 21/16,800 (%) in small worlds, 32/16,800 (≈%) in medium worlds, and 42/16,800 (%) in large worlds. Therefore, the average number of Fallen Stars per night is 40.5 in a small world, about 61.71 in a medium world, and 81 in a large world. Fallen Stars spawn anywhere within the upper 5% of the world, i.e. 60 tiles in small worlds, 90 tiles in medium worlds, and 120 tiles in large worlds.

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.

Yet, It's pretty uncommon that a Fallen Star will hit an enemy, dealing upwards of 2,500 damage. However, Fallen Stars do not damage players and can even damage bosses.

Tips

 * Sleeping in a bed will fast-forward time, which increases the rate at which stars fall relative to real-world time. This can be exploited to quickly gather stars, by sleeping for most of the night then collecting accumulated stars near the end.
 * 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. Note that diagonal platforms may not intercept Fallen Stars. In versions prior to 1.4.0.1 Hoiks can be used to rapidly pipe the stars to a desirable location, since they automatically mount them upon contact. When constructing a large skybridge, the platform to catch them should be placed at the bottom of Space.
 * To pass Fallen Stars to another player during daytime, transfer it using a storage item, e.g. a chest, since throwing it out of the inventory during the day will make it vanish.
 * If the player's inventory is full, Fallen Stars can be moved to an empty ammo slot to free up an inventory slot.
 * 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.

Trivia

 * If "used" via, the player will hold the star above their head and a will play, similarly to the Mana Crystal. However, unlike the Mana Crystal, it will neither be consumed nor have any effect on the player. This effect is left over from before 1.1, when Fallen Stars were used to restore mana.
 * The star will, if in semi-darkness, seem to be as bright as if it was shown in the day, but will not produce any light around it, similar to the Angel Halo.
