Star Maelstrom
The Star Maelstrom is a post-Moon Lord projectile sword. It summons a very large number of star projectiles with high damage output 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 like the ones generated by the use of the Tome of Infinite Wisdom. It is essentially a direct upgrade to the Star Wrath.
It has a very small chance to drop from the Moon Lord, smaller than the chance to get the Star Wrath.
Its best modifier is Legendary.
