Since this is an evil game we decided to go ahead and use a bit of DM fiat because they wanted to try another set of characters. I am still learning Pathfinder and I found the underwater combat and drowning rules to be about the same as 3.5. I enjoyed running tonight's game. Both of the other players are making Tieflings.
