Agro into pin and ko with catapult hitting backside of body. You’ll know you’ve done it right if crab sort of squats and flinches! Be very careful because these things are easy to kill if you hit anywhere else but backside of crab. Recommend having two catapults on each side since crab likes to spin around. Or place catapult on paracer platform saddle. Best of luck dudes and dudettes!
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 up/vo/te so people can see
Your crab is out of HP, and there is no annimal corpses to bring? Just put 10+ sleeping bags not far from the trap and let Karkinos kill you enough times to regain HP (as I calculated - 300 HP per death)
This works only when Kark is not fleeing. Otherwise you need to wait until torpor goes down and crab starts to attack. But this worth it. You won't lose the crab you want!
I just figured out that rocket launchers deal torpor to the karkinos, much like the rock golems, but they die a bit more quicker since they don't have much health and rocket launchers deal a lot of damage.
I understand that all the previous tips submitted were useful, but just in case it was not clear, hit the TOP OF THE CRAB, it will have a special animation if you hit it in the correct spot, and will take only a small amount of boulders to tame, even a high level. (Irrelevant with Cannons)
