Fallen Star

Fallen Stars are items which randomly fall from the sky at night, potentially killing any enemies they hit. They glow like Blinkroot, but are about as bright as a Torch. The light they give off glows through a short spectrum of colors; mainly yellow and pink. Ten Fallen Stars can be crafted to make a Mana Crystal, which increases a player's maximum mana by 20 when used.

The tooltip is slightly misleading. It says "Disappears after the sunrise," however, Fallen Stars in your inventory, chests, safes and Piggy Banks are safe. Only Fallen Stars on the ground disappear during the day. This includes stars that are dropped from the inventory, which means using caution when trying to give stars to other players or when exiting the Guide's crafting menu during the day. Mana Crystals, on the other hand, are not affected by daylight.

 * Sometimes, if a falling star hits a vertical pillar of blocks and not the ground, that Fallen Star item may float in mid air, attached only to the pillar and not fall down to the ground.
