Numbers of players in multi

[Dimascus]

I would like to know what does change when more than one player is in a game. I.e: does shield/armor/structure and damage on mobs increase or if there is an Xp penality/bonus more or less items Etc. Some1 already made a post with what I was looking for but the answer was insufficient IMO. So could we have the specifics pretty please?
