Stratus Sphere

The Stratus Sphere is a craftable post-Moon Lord magic weapon. When used, it fires a massive planetary stratus orb that can pass through tiles. The orb eventually slows down to a stop, then begins releasing sets of 6 crescent blades from itself that function similarly to boomerangs. The orb releases 5 sets of blades before fading away. Up to 6 stratus orbs can be active at a time.

Trivia

 * The name is a pun on the word "stratosphere", a major layer of the Earth's atmosphere.
 * Unlike most weapons, the Stratus Sphere is always held out by the player while it is selected from either the hotbar or the inventory.
