His ability with Traveling makes the strength correlation a joke. Clearly there is a Talent involved with this skill that isn't tied directly to Spirit or any other "strength" measure ... We have plenty of evidence that Androl is weak across the boards. He says so himself.

But it does make me wonder if Androl can go to TAR in the flesh and if he would show Talent there... But I digress ... Nothing to say his ability gives any insight into why shadowspawn can't pass through a Gateway
