Magnomaly Exo Rocket

The Magnomaly Cannon is a craftable post-Moon Lord launcher. When used, it fires a single exo rocket that homes in on enemies and has an invisible damaging aura surrounding it. Upon impact with enemies, it creates a large explosion and splits into 8 exo beams which travel in every direction. Both the exo beams and rockets can go through tiles, and inflict the following debuffs:

On enemies, these combined debuffs cause the target to be completely unable to move, lose 113 health per second, have their defense cut in half with an additional 34 defense loss, and become unable to regenerate health. In Revengeance and Death Mode, they will also lose 20% damage reduction.

Its best modifier is Unreal.
