I can confirm that Yagudo Conquistador's do drop all six elemental Ni scrolls, I think the drop has something to do with the elemental Day it is, im almost sure of this. I had a hard time getting suiton and hyoton scrolls to drop, so for those of you having the same trouble i got Hyoton on Lightsday and Suiton on Darksday.
Well... i was wrong the drops are random, i actually got 2 scrolls to drop from one mob =].
