I agree with ketaro about that, although many things from the Races books are probably also non-exotic.
On a different topic, I'm usually against revealing major villain information before the Knowledge check, but a recent conversation has lead me to believe we might like to do some calibrating. I want to make sure I'm challenging you guys, not annihilating you.
In the course of this campaign, you're going to come up against many different types of threats, and though they were design to kill each other, they'll be pretty good at killing you, too. For instance, we can all rest assured that there's not much point in overbuilding followers up to level 3, because the odds they'll survive for any significant length of time are really, really low.
On the other side of it (and I wish I weren't spoiling him), there's a villain with a breath weapon that hits a large area and does anywhere from 21 to 189 fire damage. The save is pretty low for his CR, but even at his median damage, that might be enough to reenact a Logi on your character's bones. It's probably the most egregious example of army-leveling goonery... but is this something you can withstand, or should I re-calibrate some of these threats?
