I don't know if it is THE hardest one Loss. Definitely one of but I believe High Rank 4 Horns in MH was actually harder than this. Same goes for the original fleeting shadow in MHG online. Then there's HGFFA.

There also used to be a Dual Black Gravios quest in the original arena (the one we have no article of >_> like many other arenas) which was also ridiculously hard. Gold and Silver in mhf1 wasn't quite a walk in the park either.
