Universe of Swords/Star Maelstorm

The Star Maelstrom is a post-Moon Lord projectile sword. It summons a large number of star projectiles to rain down with varying speeds and trajectories. The projectiles pierce through blocks and enemies until they are approximately 10 blocks above the player, where they become solid. Right-clicking summons many tornadoes from the Tome of Infinite Wisdom. It is essentially a direct upgrade to the Star Wrath.

It has a chance to drop from the Moon Lord.
