Mindy is a boss in Final Fantasy X-2 along with the other Magus Sisters, Cindy and Sandy. She is fought on the road to the Farplane.
Stats[]
Battle[]
Passado.
While Mindy has the least HP, her special ability, Passado, is considerably more dangerous than Cindy's or Sandy's special abilities as it can reduce a party member to less than 1/16 of their current HP. Once any of the sisters has been defeated they can no longer use their dreaded Delta Attack Overdrive. The Magus Sisters do not have any elemental affinities.
Strategy[]
Using Paine's Full Throttle dressphere to spam Sword Dance and/or Fiers on Mindy first is a good way to start the battle. After defeating Mindy the party should go after Cindy, since she has healing magic.
If the player doesn't want to use special dresspheres, a party consisting of an Alchemist and two Dark Knights is one good setup. The Dark Knights should repeatedly use Darkness to damage all three sisters at once, and it won't take more than a couple of turns to defeat Mindy. Powerful captured creatures like the Mushroom Cloud and Dark Elemental are also good choices - the Mushroom Cloud can easily hit all three sisters with Ultima for massive damage.
The Alchemist should mix a Potion and a Hi-Potion every turn to achieve a Mega-Potion. Stashing Mega-Potions also works, but Stash has a longer charge time than Mix. Mixing a Lunar Curtain and a Light Curtain may be a good idea, to grant Shell and Protect to the party at once.
