Almost done with the sheet, just trying to decide which direction to take the background. Also, two quick questions!

1) Are we allowed to use the customizing your background rule from the PHB? Specifically, the part about switching background proficiencies. 

2) Were the Noctem supposed to have a +4 stat total from their race, as opposed to other races' +5 total? Totally cool if so! Just double checking that I'm not missing anything.
