Is there any way to create Lv 50 crystals? I have header one can get schematics but I have no idea where to get them.
Off the top of my head
Blue & Red (Crit/Power/End): Daily vendors
Blue & Yellow (Crit/Power/End): PvP vendors
Cyan & Purple & Blue & Red (Exp): PvP crafting boxes (PvP vendors and Fleet vendors)
Magenta (Crit/Power/End): world drop (or boss drop?) in new daily Corellia area
Green (Exp/End): extracted from PvP weapons
Some can be bought from the PvP vendor
Some drop in Ops.
