Synthesis?

I've been wondering whether or not the quality of monsters is transfered like in HM. I synthesised a flaunt recently and had all 'ingredient' monsters at D to C grade but the resulting flaunt came out as E-, so it seems unlikely but wondered if anyone had tried with bronze monsters for example? Be interesting to hear from anyone...

I'm sorry I don't know much about synthesis but I do know that the higher rarity and grade the monster is that is being absorbed the more silver it takes. Also the mister that is being upgraded the higher rarity and grade he is takes more silver.
Hope this helps!
