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. You’re welcome!

ASA: Catapult dont works in offical Servers. User a Canon and shoot at the Back. Build a Trap and good luck.

YOU DO NOT NEED TO USE A CATAPULT.

I knocked a 145 in the cave on Ragnarok. It takes only 1 cannon ball and it has to be a shot from behind. No Limbs. Writing as of

8/2/25.

DO NOT USE A CANNON!! If you use a cannon the taming efficiency will drop all the way down to 58%. Use a catapult and shoot its back, don't waste resources on cannon or cannonballs

Actually taming it with a catapult is really tricky and most of the time your shots won't even count, from personal experience best thing is to net the Karl and place your catapult above and behind it then aim directly down and shoot

People were commenting boulders are better than cannons for taming these so I just assumed they meant rock golems. Kind of went out of my way to tame one. Doesn't seem to work for this but eh, I got a golem now. Lol

They sometimes have babies following them but mostly only seen in blue or red zones (Asa only)

Knock theme out by firing boulders at their body. Each successful hit adds 250 torpor.

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

Want an effective trap for the crab?

For about 300 stone and wood the youtuber Captain Fatdog will show you the cheapest and most effective trap

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

This thing is hell to tame without nets.

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

It is affected by a net, so to keep it from squirming in trap, net it

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

Build taming coral. Lead it in. Build pillers around it until it can't move at all. Build catapult and place up high to shoot down at karkinos. Hit top of body. The karkinos body will move downwards and rebound when hit correctly. Shoot carefully as they die easily. Good luck

If it's getting low on health almost die while taming, don't worry just use owl to heal it up so u can continue to knock him out. Up this please so people can know small tip from me.

On ASA only use catupolts, cannons no matter if you hit the head it will decrease the taming effectively, and cannons are super hard to aim you have to press buttons in more options to aim it, catupolts are a lot more easy. Up to let people know

They can be outran on foot with a bit of speed upgrades, however make sure you dont cut it close or else OH YEA MR KRABS

It takes 17 boulders for a 150 if you don't miss any
