Personality System Data Collection [WiP]

This confuses me as to how dilligence works tho. If it's not like charm exp that remains even after you unequip the stuff, then in theory switching rings or whatever else gives dilligence could delevel it?

And I have another question if anyone knows. Is the "double mastery chance" effect from dilligence referring to the chance on passing mastery books or some % on higher attacks because of weapon masteries?

I've been wondering about the 2nd half too, as I want as high of a chance to pass MW 30 as I can, seeing how expensive it is.

As for the first half, I equipped my family medal as Chamelionic mentioned, and I noticed that my diligence went up to level 1, but it said 10/26 instead of leveling up or anything..Whatever that means. I guess we'll hafta wait for profession to test things like this out.
