What is a otter used for? otter battling strategies in ARK: Survival Ascended & Evolved.
The otter will not gather pearls on aggressive you have to command it to attack 1 at a time. Also mine seems to be glitched after eating a fish it will follow a random tribe mate or try to run back to base idk if anybody else is having this problem but I'm getting tired of chasing it after every fish.
These are awesome shoulder pets, as mentioned, they keep you warm and the weight of anything in its inventory is halved but they also make great bodyguards, I put a little into weight and health the rest into melee, not only will it increase it's insulation buff but if set to attack target, will bite anything that is aggressive and gets too close, Ollie has saved my ass a few times now.
Also, to tame one I would suggest using a flying mount to pick it up and drop it in a 1x1 with a 1 door for access and bring an Ichthyornis for collecting the fish, set the ichthy to agressive and follow, stand next to the door and wait for the fish to be delivered to feed the otter.
If you want to keep it alive as long as possible, equip it with a ghillie mask as it will get the camouflage buff as well, this will help it stay hidden if accidentally dropped.
Idk y but no one has written about how to use them to get black and silica pearls.
So to get pearls u have to keep them on aggressive and on follow and let them attack fish like phirana etc but sometimes it doesnt work with normal fish called coelaths. And to get pearls u have to let them kill the fish by which i mean u have to let them last hit them and by then they will have pearl (1 or 2 of white and black or either one of em) in there inventory.
So I prefer goin for phirana and sabertooth cause they r agrressive and chase u till the shore so use that chabce to kill a lot of fish by otters. I hope i helped many which were having confusion like i did.
