I had a concern that I wasn't sure how to address with the rules, in the specific area of "Self Contained". If an isolated culture or whatever that only knows Akashic tried adventuring, it has a lot of trouble removing ability and level damage, traveling, and likely other major utility abilities. Can they Dispel, for instance? I'm not sure what the best way to address this would be; I have often found a need for some kind of "ritual" abilities to give noncombat access to some of these.
I already mentioned this on the DSP forum, so I'm looking for thoughts from others here.
