1. I plan on having a feat for this, also crossbow sniper feeat extends this to 60 feet.
2. I forgot about that, I will add that
3. I should have checked the hide skill before maing this class.
About sniping, the reason it multplies sneak attack damage is that I felt that, after all the effort you have to go through to use sniping that you should get more damage out of it(with an awesomesauce crit table this changes).
