Okay... I've only done this quest sucsessfully once... You need to get 3 friends who have the game to help you... The best thing to do is bring pitfall traps with everyone then trap each wyvern in a pitfall trap... Make sure there's a gunner with you and put large barrel bomb+'s by them then have the gunner shot the barrels causing major damage to the wyverns. Do this again untill you run out of barrel bomb+'s or pitfall traps. Then finish them out with your weapons without getting killed. This may take a while make sure you have chargers with you because if you run out of battery you are S.O.L. Good Luck =)
