Look, there are many different combinations to beat this game. I beat the game on epic and I had Matt with the ninja outfit and the rune blade, Natalie with the cow outfit and the sentinel, and Lance with the mage hat, casual shirt and shadow blaster (all equipment and weapons were at level 5 and all characters were level 30) when fighting Akron. The reason why I chose the cow outfit for Natalie over anything else is because it gives a hefty hp, defense, and magic defense bonuses. It also gives immunity to dispel and syphon. I also gave all the choco cornets to Natalie and she ended up having a little over 20k in hp when facing Akron. I think Natalie needs to be protected with high defense, high magic defense, and high hp because there needs to be someone that can withstand very high damage without dying. You know what they say; a great defense is a great offense. Hopefully, this had helped...Overall, I enjoyed playing this game.
