How do you beat the Burnt Offering quest offline in Monster Hunter Tri

When I did this, I used the Sea Striker (Ceadeus Sword and Shield) and Lagiacrus armor gemmed for attack boost M (Possible, as long as you have a 2 slot charm). Focus on hitting the Uragaan's crotch, and stick to the Agnaktor's sides. If you're pressed for time, capture both of them. If you teach Cha-Cha the Ooga-Boo and Boom-Boom dance, he can boost your attack and keep you cool at the same time. Using this, I beat the quest in around 25 minutes. Good luck!
