I'm not really trying to grind/farm any of the Obs, Explor or Commerce experience, but I've found the first two have gone up quite naturally as I've played, hunted and geared myself.

Commerce however is still extremely low, so low that give my current exp / per hour I'll probably age die before hitting the lowest threshold.

Is there something I'm not doing? Is there are simply way to grind it up?

Appreciate any advice. Thanks.
