Recently I noticed that SoulFire isn't working as a lightsource for me, and I remembered it used to be one years ago. Today I checked the wiki, and that said it should give the same light as a greater lightstone. At the advice of some guildies I put all my gear in bags until I had nothing, then put SoulFire back on, but I still had no light.
