I’m no expert but I think I’ve found the best way to tame these guys. All you need is an Argentavis and 5-8x primitive spears. Our plan is to snatch the otter from the surface of the water with the Argy’s mouth grab (click right stick or C on pc). This part might seem a lil daunting but I believe in you. Once you’ve scooped up the otter keep it in the mouth of the Argy and find a nice body of water with plenty of sabertooth salmon. Land on the shore close to the water (the otter will stay in the argys mouth). Now use the primitive spears to kill sabertooth salmon (or any large fish). When killing a fish with primitive spears it will automatically start dragging the body. Now here comes the best part. With the otter in the Argys mouth which will be raised above you, it is actually possible and super simple to feed the fish to our otter friend. You now have an Otter with none of the headache.
The otter in Ark ASA the Island map can be found in the northern part of the red woods, and major river ways. The spawn points make them hard to find, and since the otters are so tiny. There is a small spot in the swamp area where they spawn but recommend not going there since there could be kapros, sacros, and deinosuchus’s (if you have the mod). Theres also a small lake in the redwood towards the west where you can find them
Chapter two: taming
There’s two ways, an easy way and more difficult way. The easy way is you want to find it and you want to have an argentavis and catch it. It will be in your argie’s mouth and you would want to catch fish, preferably sabertooth salmon, (1.5x size is the best). Kill it and drag the body to the otter and feed it. The harder way is when you find it in the water. You just wanna kill fish and drag it towards it and feed it. It’s more difficult because you could lose sight of the otter, or it could die.
Chapter 3: Utilizes
One major utility is that it could regulate your body temperature. When you pick it up on your shoulder, it gives you heat and cold resistances. This could help you with longer expeditions and the north of the island. You can get better resistance if you increase their melee damage. Another utility is that it could hold more than one artifact at a time, unlike you and any other. You can put hats on it, which makes it look even cuter than it already is. Hopes this helps!!
These little guys are so much easier to tame in mobile, but harder to find. You still need to kill a megipirahna, but you don’t need to grab its corpse to feed the otter. After harvesting its meat you can easily walk up to it and feed it until it’s tamed. It doesn’t run away in mobile, and I’m sure you can use any fish meat.
I have 6! 4 of them are common colors, 1 is green and magenta, and the other is pink and purple!
Okay, so the way I tamed them is simply by first: kill any dinosaurs near it or in range of otter, next eat a rare flower, then it will come up to you and nibble on your argy (preferred mount cuz it can pick up the otter in beak), then use a ithyornis (or a weapon to kill the sabertooth salmon if you don’t have a ithy yet), then drag the magical (or less magical) fish over to the otter and feed it!
Worked 10/10 for me (it can get a bit annoying when the fish keeps getting in your face)
