So my friend is starting up a new campaign in Pathfinder, level 15, and we can pretty much do whatever we like as long as we're not evil. That evil bit foiled my initial plan so I decided on something I've been mulling over in my head for awhile now, a Dwarven Battlerager.
I'm trying to roll one up in Pathfinder and was wondering what you guys thinking would be a good class combo to make a battlerager in Pathfinder. I was thinking: Fighter 6/Monk4/Barbarian 5.
I was also wondering how multi-classing affects your defenses like Fort, Ref and Will.

What do you guys think?
