How about splitting edges into "convenience" ones like "calmed mind" and capability ones like synergy of suffering?

Then you could once more allow decent edge points from stuff like exploration, but restrict some of it to being spent on convenience edges.

So people would have more edges but none of the extras, relative to what they'd get now, would give a pk advantage.

As it stands I feel it isn't worth edge points on a convenience edge, but I can't see why you wouldn't let people take them without sacrificing the edge they'd be taking currently.

Thoughts?

Also could make some newbie edges that mean you don't need to eat or drink as often. Reduce the burden of keeping yourself feed, which as a newb is quite a burden and leaves little coin for anything else.
