XP and Death...

[Illusionist]

Please excuse the question if it's been asked before (I had a look around and couldn't see it), but...

1. Can someone please explain to me how XP is given. In other words, if I kill a mob on my own, does that mob have a specific XP value? What if I kill the same mob with another player in a group - is the XP halved, thirded (?), etc.

2. What happens when you die? Are there any bad parts? Do you loose XP, gold or anything? Or does it not make any difference if you die or not?

Thanks in advance.
