Very easy to tame if you know what your doing. First tame an Ichthyosaur. Then grab a crossbow and some tranq arrows and find one and knock it out. It is not be able to attack if you are on the Ichthy. As you are taming it, be sure to remain on the Ichthy unless feeding narcs, so other creature don’t hurt you.

These are one of the few dinos that take less damage/topour from head shots. Aim for the body.

I tamed a lvl 40 Dunkle with around 60 tranq arrows and 10 toxicant ones. Insta tamed it with titanoboa kibble (using 10x soothing balm boost). It's pretty hard to knockout and takes quite some time in my experience at least.

When it says 1.7% chance of death. It means it's going to die.

Taming a dunklosteous is not too hard if you do this.

1. Get lazurous chowder or scuba gear

2. Have kibble or prime meat ready

3. Have at least 2 good crossbows. Kill some alpha raptors to get some.

4. Use a mount. I recommend a Sarcosichus or a Baryonyx. Make sure you can fire off of its back.

5. Find one. They typically spawn near the edge of the map on The Island.

6. Clear out any hostile creatures that are too close. They will interfere with your tame.

7. Shoot it full of tranqs. This may take a while. They are slow, so simply kite them while riding your mount.

8. Once they are knocked out, put kibble and/or prime meat in their inventory. They may need narcotics depending on the level. Make sure to protect them.

9. You now have a Dunklosteous! I suggest bringing a cryopod because they are very slow swimmers.

Hope this helps, good luck! :)

Bring more tranq arrows then you think! Mine took 100 at close range, on the body, at LEVEL 3.

I took cooked prime meat (stays better longer) and got mine in only four feedings. On an icthy they don’t chase (mobile player here) happy taming- Survivor Belle

Anyone else surprised that their not hostile

Be sure to bring lots and I means LOTS of tranq arrows 150 at least to be safe avoid head shots....obviously

Apply a few mins extra on due to server lag on ASA
