Meropis
Coralia helped her subordinate that was stabbed by Mira up, summoned a small pool of water, and tossed her into it.
The mermaid's injuries started healing at a rate visible to the naked eye and around 10 minutes later she was fully healed.
"We mermaids gain additional benefits when we are in water such as increased speed, strength, rapid healing, and various other things. While when we are on land, our tails form into legs and we gain a bipedal form that allows us to walk on land. You can probably guess the benefits for living on dry land compared to the sea." Coralia explained when she noticed Mira's group looking at the once injured mermaid with interest.
"I see. Those are some nice buffs and yes, I can guess a few things. Like making weapons and armor, safety, and other things that might be more difficult underwater." Celaine answered in understanding.
