I just defeated 10* caravan Silver Rathalos... My god that was the hardest thing I've had to do in this game yet. It seemed like he was enraged almost the entire fight, and most of his body was too hard for my blue sharpness switch axe to cut (thank goodness for sword mode mind's eye). Those poison claws are so powerful that the time I finally beat him I didn't get poisoned once since dodging them became so essential. The worst part about the fight is the fact that I now need to go back and beat it again to get the rest of the materials to upgrade one of my switch axes, but I'm sure I can pull it off if I bring flash bombs and traps with me next time.
