This is my usual run with Rathian. I suffer at first whether i will use the flashbombs or not, though in the last part i ended up using 5 [only 3 worked] because i don't want to have the trouble of chasing her around, and I messed up with the item [hahahaha].
But all in all, i think, at least to myself, did it great.
I STILL HATE those HATEFUL BULLFANGOS!
Hope you like it!
