The Coral Staff, as its name suggests, is made of mostly pink coral with a cluster of red and purple coral for a head. The head also features a small sea star and a large pink conch shell.
This aquatic staff provides Natalie with an above-average boost to Magic Attack and a small boost to HP and MP. It increases the user's resistance against Fire and Water elements, as well as Burn status effect. It also boosts the power of Natalie's Water attacks, and allows her to cast Bubble Blast with certain weapon-element skills. The Coral Staff is fairly useful when dealing with Fire-based enemies, as it both enables Natalie to inflict high Water elemental damage, which is often their weakness, and protects her against foes' fiery attacks.

The Coral Staff is found in one of the chests on a screen right after the battle with Rafflesia.
