Okay, done with the place, got out and explored the far west part of the map, went back to town. Here is the plan: I change up my pc's classes and get inventories cleared out. Then I get my weapon's ready. Going to kill the Boss Vamp in the place, then go kill the Irish dude, come back get my exp and then do some deep sea diving, then go for my end run.... only prob is I'm not sure where the finale takes place. The only place I can imagine is through the Hydra? Only so much of the map yet to do.
Good tip is if you are going to change npc levels and you are not close to the next level on the former thing, change before you get any of your quest points, especially in the last town. I leveled up 4 times just in town!
