Took a run though the swamp. I got bitten by a titanaboa. I died, respawned and saw, you otter (lvl 3) killed a titanaboa (lvl 30). Do not underestimate. Unfortunately, 2 seconds later I see, your otter (lvl 3) was killed by a titanaboa (lvl 10) one up for my harry otter?
They can carry multiple artifacts, even on official, and provide hypothermic insulation against the cold. Literally a must have for running artifacts if you plan to spam run boss fights for element. 10/10 would smash again.
Mobile player, I was doing dodo hunt (kill 250 dodos. Not as easy as it sounds) with my Griffin and my otter, and my otter FELL OFF MY SHOULDER and landed in water full of mega. Then I start getting messages, "your Harry otter (otter lvl 57) killed a megalodon (lvl 30)" I got at least 5 of these. Go OTTERS!
