Actually another thing with Quina and the Grand Dragon grinding which is a bit riskier but works just as well and is accessible right when you first get Quina is devour a Mu, that gives you Limit Glove. This skill only works when Quina is at 1HP, but hits for 9999 damage. Also make sure to have Freya in your team as every dragon you kill when she's in your team will make her future skill Dragon Crest much more powerful. Make sure everyone is equipped with Antidote ability. Equip Freya with the Coral Ring (if you let her win the Festival) or Zidane if he has the Escape ability (You can't normally run from these fights at your currentl level.) While in the Grotto, kill off Quina and go to the moogles and save. Use a phoenix down (you may have to reset several times) until Quina comes back with 1 HP. It is vital you keep her HP at one, otherwise this trick won't work. Save and go topside.When you encounter a Grand Dragon, have Quina cast Limit Glove once. Then on her next turn, have her use Eat. If Quina gets KO'd, reset and try again. After each successful try, save the game. Use Phoenix Downs to revive people and ethers to feed Quina's mana
