Wow, can't remember the exact modifiers when i did skolas for the first time but lightswitch wasn't there. If it was, I would've waited until the next week. Took my group about 12 hours the first and only time. Arc burn omnigul was pretty bad, it would take us a while. My first oryx I got lucky, was in a group with 4 experienced guys and myself and another were new. Got it around the 3rd try.
