One of the many relic weapons of myth.
Though unknown by many, this one is somewhere in the D.H.R. Wilderness yet to be recovered. The thing is said to shoot rainbows, and despite being a laser weapon is capable of a handful of special effect damage, each attributed the related colour in the rainbow beam. Red deals fire damage, blue frost, yellow lightning, green poison etc in addition to the laser damage itself. The lense being made from more then one crystal polished into a lense, and cut up and only a section of it being used to make a complete multi crystal lense. To top it all off, being a las cannon originally before discord modified it, the weapon possess a decent anti armour capability.
