Does anybody know how to beat Vegnagun on Final Fantasy X-2?
What I reccomend doing is completely leaving where you are and returning to Bevelle. Then, go into the temple and find the Kinderguardians. Go into their portal thingie and continue through the levels until you reach the boss on level 40, Black Element. To defeat him, I reccomend making all Paine and Rikku Dark Knights and having them use Charon against the boss. It only has 9999 hp so it dies quickly. After you beat it, you get the Catnip accessory. What this does is makes all of a character’s attacks do 9999 damage if their hp is critical. Give the catnip to Yuna and have her use Trigger Happy against Vegnagun when her hp is critical. You can get multiple hits of 9999 in if you tap fast. Bye bye, Vegnagun!
