Who can tell me anything on how to beat the Magus sisters

They're not really that hard. You either want to attack them all at once, or attack them all together. I suggest you bring your two highest level girls in Dark Knights and the other as White Mage. Set up a good defense with the White Mage (Shell, Protect, Regen, etc.) and have the Dark Knights use Darkness each time while the White Mage heals them when their HP gets low.

You may want to boost all three girls' HP and the DKs' Strenght and the WM's Magic.

Kill Mindy first, since she has the least amount of HP. Have a white magic handy so you can cast 'Dispel' when they use Not So Mighty Guard. It is important to knock out atleast one of the Sisters ASAP or else they will perform a powerful attack called 'Delta Attack'.

Once you kill Mindy, focus your assault on Sandy.. Followed By cindy.

I dont know why your having any problems with the sisters, they were extremely easy for me. What level are your characters?

I also see, that they have no weaknesses. Goodluck!

*I took out some parts of the FFX-2 Strategy Guide and posted it here, i hope its okay*

The problem iz when I go try to kill Mindy they use Delta attack

It sounds like you're not leveled up enough. Remember, you're in Chapter 5. Just go somewhere else, like the Bevelle Via Infinito and gain some levels. If you can beat the boss on level 40 there, you can get a very helpful accessory called Cat Nip that lets all hits do 9999 damage when your character is in critical status.

If they're doing Delta Attack, it sounds like you're not focusing hard enough on getting one of them out of the battle. As soon as even one is down, Delta Attack is out as an option for them. Pound away until just one is down and then go for the others. Mix Elemental gems on Alchemist if you have it. If you want, you could also switch into a special dressphere and that should be enough to knock them down hard.

P.S.: You're bucking to really annoy me bad with these thread titles of yours. It really helps people if you use thread titles that actually describe what the thread's about. Just calling this thread "Aeon" doesn't really say much about it.

Demon9999, out of all the people I know, you were the last person that I thought would have trouble with a game that you had way, way, way longer than me. To me, the best and quickest way to get rid of the magus sisters is have someone be a gunner and give the cat nip and haste bangle.(make sure that the gunner is low on HP before fighting the sisters.)Get the first attack and use trigger happy on the smallest one of the group. She uses the move that is like gravity. After that, you practically won the battle, but make sure that somebody is ready to bring the gunner back to life I.E.- Alchemist, wht. mage, or pheonix down.

jus attack the small 1 first till u kill it so they cant use overdrive then go for the tall 1 and then fat 1
