Maker and Black/Dark Crystals

Archer shoes with Int?

Since black/dark crystals only can change your stats 3 points above or below, and since there ¡s apparently no chance for it to fail (change nothing), should I guess that the probabilities to get any change are:

100/6 = 16.6% to all?

that is:
-3 = 16.6%
-2 = 16.6%
-1 = 16.6%
+1 = 16.6%
+2 = 16.6%
+3 = 16.6%

Excuse me if I am wrong I dont have much idea on what im doing, can someone check this? :f6:

I think it works like that chart I posted above. It certainly could do nothing to your stats.

Oh, and I think I've had my question answered: Dark crystals are (or can be) applied AFTER other crystals. I wonder if it actually matter what order you put them in on the creation screen.
