I really need helpa s evrae kicks whooping my bottom and it's starting to really hurt... *watches the tumble weed go by* Ok so maybe that wasn't funny but I still need help.

This is my party and what I have them doing:

Tidus- Attack, pull back/in, haste others and immune to poison though sometimes hegets killed by that bad breath (think I would to). Overdrive = warrior
Rikku- Albhed potions, attack, pull back/in, throw objects and immune to nothing (so what i ran out of money and objects to upgrade with!) Overdrive = stotic
Auron- Attack and immune to petrification (I mainly have him cos h's myfave character and strong!) Overdrive = warrior

Things I have nothing of:

Mana spheres

Spells I don't have but have heard I need:

Slow and reflect

As you can see I'm a little doomed here so please help me!
