Additional Creatures Wiki

Acrophyseter are mammals in Additional Creatures.


Smaller, docile whales related to the larger Zygophyseter and Livyatan. Acrophyseter are friendly and docile cetaceans, and this often draws them to the earlier survivors who are trying to explore the ocean. They are friendly enough to be handfed and easily domesticated, making the ideal step-up from Ichthyosaurus, and able to fend themselves off in battle more easily. With various increased damage output from deep-sea-critters, these whales make ideal counterparts for diving into the deep at your own risk early on- with some helpful advantages to watch out for your survival.
