Monster Hunter World Iceborne Alatreon vs Greatsword

Going back to an old build to see if I could beat Alatreon with the Greatsword again. Last kill with Greatsword was back when Alatreon was first introduced to the game. This Build is for the Ice Alatreon. Using fire as the main elemental damage. Also, not my best work with fighting Alatreon.
