Searching? Searching for Magic Sites?

[rsolow]

And one more question....

If there are only 4 levels of difficulty for finding magic sites (page 44), why does Acashic Record (page 209) peform "level-9 searches" ....wouldn't a level 4 search reveal all magic sites in a province since there are only 4 levels of search difficulty?

Put another way, what is the advantage of a level 9 search when a level 4 search is all that is required to find even the most well hid magic sites in a province?

No advantage really, except that if sites that require more than 4 levels appear in a patch or mod or something, Acashic Records will be sure to find them too. All the other path-specific searching spells also search at level 9.
