See, I think now the spell should be made even LESS reliable, but maybe a little better on _average_, so actually very good when it works. And require mountain terrain. That way, one can't just go around automatically finding hidden tribes everywhere. And most importantly, the T-shirt will still be valid comedy, and the players who hate to get unlucky will still be annoyed and not use it, even though on average, they should. ;-D
