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! :)

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

Normal creatures require “light torpor” to knock out and tame. But with the karkinos, astrocetus, rock golem and titanosaur require “raid torpor.” Raid torpor is dealt by cannons or catapults.

Cannons do not lower efficiency, one hit knock out, catapults are broken on ASA.

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

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

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.
