Otter babies are very easy to raise, as they hold and entire 25 pounds of fish meat when first born. Not sure if this is an oversight, but just fill it with meat once, then refill a few more times before it hits juvenile. Can be hard to claim when first born because they tend to bounce all over the place. Overall very fun and easy to raise.
Level melee for it to keep you warmer/cooler(idk why) more melee=more insulation
Level weight for storing artifacts inside it it can carry multiple artifacts and is the only tame able to do so also hide your bps inside em when you get raided only soulless people would kill a passive otter
