Perhaps I'm missing something, but I cannot find anything in the book about how reptiles would be able to remain active in winter.
Without giving anything away, there is a reptile character in the campaign who do this and that throughout the winter, but I'm perplexed as to how a cold-blooded reptile would be able to do much of anything in sub-freezing temperatures.
I am inclined to have them remain in semi-hibernated state through colder months. Perhaps have them sheltered from the elements and participate in plots and plans while tending the homefires (as it were), rather than out and about in the snows and ice.
Thoughts on this? Am I missing something evident in the rules/setting? Would mutated reptiles merely not be cold-blooded?
I've been wondering since stumbling through the Swedish version last summer, and since I'm (finally!) having initial sessions this weekend for a campaign, I want to figure this out before we get into full swing.
