There, just redid a goodly portion of the thing and now it has a full ten levels filled.

I'd make the intelligence boost in the cold environment an "enhancement" or "morale" bonus instead of an unnamed bonus.
Yeah, made it a Circumstance bonus.

And, speaking as one who lives closer to the Arctic Circle than he might like, I object to -50 being described as unearthly. Really freaking unpleasant, I will grant.
lol, I was just using the Frostburn temperature band names.

There is Cold (40 to 0 degrees), Severe Cold (0 to -20), Extreme Cold (-20 to -50), and Unearthly (-50 or colder).


Look better, Nows?
