Starfall

The Starfall is a Hardmode spell tome dropped by Astrum Deus. When used, it summons 5 purple stars from the cursor's location, which travel in a downward spread at a high velocity. The stars do not pierce, but they can go through blocks.

Trivia

 * Its name and effects could make it a reference to a weapon with the same name from the Exxo Avalon mod.
