So, my strongest person (Wakka) can do 9999 damage. How can you make it so that characters can do more impact? And Aeons. Only Bahamut can do more than 9999, and I have no clue how that even happened 0_o. Help?
Sorry, I misunderstood your first response. Are you sure they can't do more than 9999 with a regular attack? I'm pretty sure that they can...I just don't know how.
You need to get the celestial weapons for each character to get Break Damage Limit (ie. it's one of the abilities that comes with the celestial weapons.). I'm not sure if you can get them in the American version, but they're definitely in the Int. Version. You can also get Break HP/MP limit too...
Ohhhh, I see. I hate that thing. There's only one solution: level grind until your fingers bleed! BTW, once you get a character's celestial weapon, an aeon gets Break Damage Limit. Getting Nirvana gives Valefor BDL, and so on.
You need to use the "Insert planet name here" crest on the Weapon to make a certain Aeon Learn BDM. Also,to make the celestial weapons learn BDM,you need to use the Crest and the Sigil of the character on the weapon. I think for Tidus is Sun and Yuna is Moon,the others can change depending on the version.
Zanarkand trials? There's nothing in Zanarkand that helps with celestial weapons, except tidus's sigil, which can be obtained before the dark aeon appears, and if you don't have the PAL or international version that doesn't even matter. Read a guide on gamesfaq about Celestial weapons, each character has one and two items for their weapon to unlock it's true potential, and there's several ways to go about getting them all, some are hard, others a pain, but reading a guide online will make it clear, the easiest ones to get are aurons sigil and rikku;s sigil, yuna's also doesn't require much effort. But yeah reading a guide specificially for the weapons will make your life easier.
