Battle Reward: Moon Ore
This is a rare battle where Oreana is not a good choice to have in the team. The constant presence of Spell Reflect makes her magic power useless at best and in the worst case kills your team. The good thing is, all physical special attacks are not affected by Spell Reflect.
Mave is very dangerous if she uses one of her special attack skills Sonic Boom or Calamity Star. Both deal heavy damage to all your team members. I recommend that one member has the Treasure of Light equipped and is charged to use. It will give your team a good buff for a while. Start the battle by attacking Mave with strong single target attacks like Heracles Blow, Rapid Slice or Divine Blow.
Use Elysha or Milka to heal your team each turn. Don’t bother buffing your team with offensive or defensive buffs. The battle is not noticeably shorter that way.
If your team is in good condition steal the Crystal of Life from Mave. If you feel your team can withstand a round without healing you can also throw in a Lost Guard on the enemy to increase the physical damage inflicted by your team.
With this tactic Mave should fall in around 8 rounds. The Snipe Pixies don’t have any strong attacks to harm your team significantly so the rest will be no problem. The battle should actually be over in around 10 turns.
