If I´m not mistaken, this is a special Brachydios who is know as "Hell Bracchidios" in Japan. Apparently he  always goes into rage mode after you hit him ONE TIME, and has increased attack, defense and health. Not sure if it´s this one but if it is it can be a long and hard fight. Some players consider this one of the hardest quests ever. And yeah, that quest apparently gives an item needed to craft an hammer but I´m not sure if it´s that Healing Hammer. Never heard of that hammer before.
