Ok thanks Slashley.
This means that with soul weapons and dokimasia weapon from the shop won't work for getting weapon fragment?
I see that Lucent weapons need tons of Jewel Memory, assembling a full team with the same weapon will definitely suck since there is no indication of which weapon pref are on the hime profile pick. Guess I'll spend forever over the wikia...
EDIT: I forgot that the filter sort tool was improved, might not be as hellish as i thought.
