Tranq Arrows/Darts DO NOT WORK!!! To knock this out you need to use a catapult and shoot in only on it's back. If you shoot it on it's legs it will kill it.

Cannon balls discrease taming effeciency significantly! So for high tame level, always use boulders. Please let other people know! :)

Pretty easy to tame. Trap it in a circular form of stone Dino gates, place catapult low if catapult is high the crab will die. Then shoot it with a catapult. Cannons insta kill the crab, do not use cannons

This tame is like the Rock elemental, but do not shoot it in the head. Shoot it right in the back of it's shell. Anywhere else will kill it fast.

To the guy who said "rare on floaty islands on crystal" that is a load of crap found 20 on 1 ISLAND!!!

Watch YouTube video from captain fatdog karkinos trap and use this to tame them. I struggled so many times and then I realised you can't do it going up a hill. Flat surface and hitting it in the head are the two main problems but as soon as I had got it right it was so easy.

Up for noobs

Using a cannon will ko any level crab in one hit, but will SEVERELY drop taming effeciency. If you want one quick, use cannon. If you want a high level use a catapult (the inferior siege weapon).

You can tell if you shot the legs if it throws it’s arms up in the air when you shoot. If it doesn’t move at all when you shoot that means you shot it correctly, so make sure you don’t get it to throw its arms up when you’re nocking it out

Trap it with bear trap and shoot catipults into its body to KO

You can use explosive arrows on the tek bow to knock out
