Ladies and germs I present to you the Z-saber REDUX. I decided to fixed up my old z-saber sprite a small bit, gave it a more curved blade. It also comes in 3 different flavors; Legendary Lime Green, Power Nightmare Berry-Punch, and Throwback Blue.
Well hopefully Ryan's Senergy is compatible with the saber's energy emitter. Otherwise the saber would theoretically unleash an energy feedback so powerful the saber itself would rupture and explode, wiping out everything within two miles. But that's just a theory.
Synergy Crystals are universally compatible. They adjust power output debending on the energy blade, if it is in the Synergy Database. Your Z-Saber was added to the database 7 weeks ago, so it SHOULD work.
