I went with lagiacrus armor and a fully upgraded rusted weapon i got the dragoncore hammer and so i learned how to use it and then confronted it and repeated blows to the head, while it is swimming it will "move" your character with you so, more attacks to the head the in the final area i already had mounted bowgun shots and used the dragonator and then when it was distracted with cha-cha i would blast it with the long range shots--- close range in the final area never really worked for me, and electric or fire weapon with high sharpness could work too,
