[Cainehill]

Don't think I'd ever do it, but someone might find the water, fire, or earth path worth taking to 10 as well. That extra point of defense or attack rating might be nice, likewise the extra point of fatigue recovered each turn.

Perhaps more importantly, for fire and earth, is the benefit it gives the pretender as an artillery platform, plus the extra point armor from earth, extra point offense from fire.

Come to think of it, some might consider Air-10 also - extra precision for the pretender, lower fatigue cost for the big combat spells, and better missile protection for the sacreds.
