Just in case anybody was wondering how many of these it takes(roughly) to get 99-100, I personaly made 24 cursed soups for a total of 0.6 skillups.
I got the other 0.4 off red curry, I only did this when dragon meat was cheaper than red curry. I got the 0.4 off 7 synths(I think this was an extremly lucky rate of skillups).
The first 11 cursed soups i made actually gave me no skillups at all, so dont give up if you have a bad run. Those royal jellys are annoying to farm, but it is perfect for leveling up your NPC if it is not already higher level.
