Nearly 20 scales here - it's a super fun fight as long as you aren't with dips who will take all three deaths by themselves. Granted, I have been doing the 4 Tank strat and it's been smooth as butter. No need for pesky squishes. My DPS/Heal only friends do not like this fight.

Also, the Rathalos mount does drop from the fight! My friend has it after 2 runs. I just got a Poogie from the chest. >
