TechnicolorCosplay, a Krystal Kigurumi cosplayer, has recently started work on creating a Krystal Staff. One of the interesting aspects about this one, however, is that it actually will glow. The shaft is made of a clear acrylic tube and gold vinyl wrap, cut to resemble the actual staff markings from the game (using my Staff Texture image as reference). A blue LED will shine down the tube into a white diffuser material to create the blue glowing effect. In upcoming steps, the shaft head and end will be built, though I don't have info on how those will be built. Looking forward to more progress.
On that note, TechnicolorCosplay now has a Twitter Account. You can follow the cosplay and Staff updates there.
