[Squirrelloid]

mod all sites to require pathlevel 0 of the relevant path. They'll all start revealed (although you'll have to conquer the provinces).

Alternately, mod Strands of Arcane Power to be Evo 1 and cost 1 pearl. Give your pretender high astral and 1 in every other path, and cast it. Wait a few turns. (Again, you need to conquer the provinces). Will not find holy sites, but this is a faster mod than modding all the sites. (I suppose you could just mod the holy sites to be H0 if you were doing this...) I also think this can't find X4 sites at all, but I'm not sure, and there are very few of those anyway.
