Evolved from Water Spirits, learning WaterSpear in the process. Alternatively they can be recruited in rainy weather.

They can 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.
