As far back as I can see, Granz has always dropped Lilliparium (XS) in JP. I figured him not dropping it was just because of there being no crafting in the game, but now we have crafting and he's still not dropping any.
Considering there are no rappy spawns in Ult Lillipa (which can currently drop Fornis weapons and more due to Summer event), this was pretty much the #1 reason to run Ult Lillipa instead of Naverius. Instead it's not there at all, so... I'm confused.
