Plant Mermaid

Combat
An Aquatic support unit with good Mana and Magic growth. WaterPath and WaterTrail allows them to make water tiles, while DrainWater can turn water into earth, making them useful for changing terrain. Note that DrainWater also gives the Plant Mermaid magic charges and shields. They can also act as healers with SpawnHealFlower and Rejuvenate, though neither are a means of directly recovering Health.

Overworld
They are the only starter species with Oxygen Provider, making them invaluable if you're looking to explore water Portals.
