Due to mutations, sea trolls have become viable hunters on land and in the water. Those that have mostly piscine diets have even taken on some of the physical traits of their prey (see Piscine Mutations under Actions). Due to their extended time spent in the water, sea trolls have a heightened sense of hearing similar to echo location instead of smell. Their bodies are more resistant to fire as well. However, they are vulnerable to thunder damage, so much so that it arrests the regenerative properties of their flesh.'
