The Refraction Rotor is a post-Moon Lord rogue weapon that drops from the Exo Mechs after XM-05 Thanatos has been defeated last. It throws out a gravity-defying disk that travels through solid tiles and pierces up to nine times. When destroyed, the disk shatters into 6 homing rockets which each deal 49.5% damage, along with 6 gravity-affected metallic gore chunks which do not deal damage.
Performing a stealth strike with the Refraction Rotor will cause the resulting disk to burst into more rockets instead of gore chunks. The rockets replacing the gore will travel faster than normal, and deal 60% damage. The main disk will deal 75% damage and the main rockets will deal 37.125% damage.
Its best modifier is Flawless.
