1. ok I've played a demo couple of times and I've noticed that there were those yellow light points that were disabled in the demo so I thought I can teleport between them is that what you're talking about?
7. I've seen on some trailers that for example the flaming sword was generating it's own light that was reflected on the character itself and the enviroment as well but I don't see it...
1. Those are savepoints. Teleport points will be giant waygates. Hard to miss. You'll have to quest to gain the power to activate them.
7. Not sure, I have the settings fairly low. However lights, spells, fire etc will illuminate your characters.
