The Space Gun is a magic weapon which is similar to the Laser Rifle in the way that it shoots with a high rate of fire that inflicts 18 damage and uses 8 mana. However, when used with a full set of Meteor Armor, the space gun will use no mana, and will deal 21 damage. The Space Gun shoots lasers which emits green Light, alike to Glowsticks, but of a richer, deeper color.
The laser will pass through two mobs and then dissipate if it hits a third, making it possible to kill three enemies at once with one shot.
Another unique property of the Space Gun is that it makes a distinctive noise when striking a solid block. This can in theory be used to locate Floating Islands by firing into the sky and listening for an impact. However, as the noise is diminished over distance this is ineffective if the island is over around 100 blocks away, as it becomes inaudible.
Although the Space Gun's name has the word "gun" in it, it does not fill the criteria for the Arms Dealer .
Sometimes this item can't be crafted.
If you drop all the materials and pick them back up, it should fix this problem, and you are able to craft it. But remember: Stars disappear during the day when dropped.
