We should give them Disguise as a class skill, and let them use it to Disguise themselves as other bright lights, like lighthouses, auroras and St. Elmo's fire.
How about max ranks in Disguise, 5 in Bluff, and 4 each in Listen and Spot? I don't think we really need Search. If you want to keep it, shave a rank of each of Listen and Spot?
