Tips & Strategies

Handy trick, if you're playing on Fjordur and want a high level DO NOT go to the Aberration Cave. There is a second Aberration cave near the Vannaland (South) Southeast teleport. Go inside, and if you find a low level kill it and harvest the corpse. Then do a lap of the cave (make sure to fight stuff to slow you down as if you run too fast this doesn't work), and you should have another spawn. I used this trick and in 5 minutes I had already killed 7 Karkinos, and they were a mix of levels. This is also a great way to farm Organic Polymer. Hope this helped

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 up/vo/te so people can see
TRANQ ARROWS DON,T WORK you haft to shoot a cannonball shoot it in its head if you shoot it in the leg or it will die. Up if helpful
Net projectile works on these, so craft your catapult and boulders, find your crab and net it. Proceed to set up the catapult a few feet from its face and you can easily just fire all required shots before the net expires. Youβre welcome!
If you are missing with your catapult and it's dying, drag dino corpses to it and let the karkinos eat the corpses. It will heal him up a lot then try again with the same torpor you left off with.
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!!!
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)
