Blueprint or Made Up: Blueprint

Components: Rip core with directed ejection field, Plasma core with diffraction torus

Attachments: Acid bath, ammo support

Again, for the reference. You're gonna be making great plasma all day! The saw blades shoot out at lightning speed (though without lightning damage, unless you want to swap out the default acid bath for an electric charge). And the diffracted plasma core brings back Isaac's old ability to point the weapon at the ground and let loose a shockwave that sends enemies flying. It doesn't do a ton of damage, but it's great for crowd control. Besides, those saw blades take care of the damage.
