Orb Fish

Evolved from Water Spirits, learning WaterSpear in the process. They can be evolved into three different types, a Magic Level Type that learns ExtractMana, a Support Level Type that learns Calm, or an Average Level Type that learns WaterShield. They can then be further evolved into Shell Drakes, Sea Serpents, or Water Mermaids, but note that Shell Drakes and Sea Serpents have genetic value requirements so choose your skill carefully. You don't want Heal on a Sea Serpent, or WaterPath on a Water Mermaid.
