Swamp Seal

A rare Seduction based Creature, they can be found in the Swamp mini-biome. It's unconfirmed but rain may increase the odds of finding one. As a Seal they play a part in granting you access to SealHaven.

They have a special passive that grants Poison attacks to all Seals, and combined with their Strong Pheromones their attacks can be dangerous, particularly to characters weak to Lust Damage. They can get skills that allow them to inflict Lust and Poison from a distance. They can also use Lure on the Overworld. To use them optimally make sure you can keep their Mana up. Beyond that they have both Water Mount and Oxygen Provider, giving you all you need to explore Water Portals.
