??? Maker

I tried those too, because I was thinking "How else would it know what level of Secret Crystal to give you?" but no dice. I even tried adding a basic Dark in there but still nothing.

Wait did you use all basic? Because i was sorta thinking maybe you had to use all advance crystals and from their the game decides whach level it is (with the same chances like grading crystal jewels)

Hmm i just got an idea, did you try putting all 5 crystals then putting a black crystal? Because to me, the dark crystal and black crystal seem to stick out from being normal gems invloving maker, and well..theres 6 slots

EDIT: Also might wanna try wearing thtat gordon iron pendent? I dont know maybe you need it? o.o
