The Event Horizon is a Post-Ancient tier flail that also drops from Zero. Like the Solar Eruption, the tip follows a narrow arc in the general direction of the cursor before retracting & can travel through blocks. When the weapon hits enemies, it creates small blackholes that linger on the air for a short time.

Its best modifier is Godly.
