I don't think we have enough info to know how worthless works. Does it have a range, is it point and shoot or is it by voice. As far as we know it's based on his understanding. Without knowing more that's the only weakness and then have you consider what his balance breaker might be. Of course that's assuming if he has one although that wouldn't be surprising.
