I see that they can vary in stats, such as resists, is it possible to get one with the highest possible in all resists? As you train the Cu sidhe does the resists go up or are they always going to be the same as when you first tamed it? What is a good way to judge if a Cu sidhe is worth keeping? What resists/skills should I look out for? I've been going by the barding difficulty, high barding difficulty = tougher?
