When knocking out the elemental. Short is with your taming tools (rockets,cannon) etc. Back up a bunch till it goes into rock form then shoot a arrow at it to wake it back up. Use the time in between disguising itself and waking up to organize yourself or your team for the next attack of cannons.

When you are knocking out a Rock Elemental the best way is to let it agro on the pillars or dinosaur gates before you start to shoot it with Rockets or cannons,because The elemental will stay still for a moment in time.Cannons are cheaper to use when knocking out Rock Elementals.Just trap it,let it agro on the pillars or dinosaur gates and fire! Oh don't forget to make your pillars or dinosaur gates out of stone or metal.Thats how my tribe gets all of ours down. :)

Best way to knock one out is to lead it through a narrow valley to get it stuck then shoot it with a cannon in the back of a paraceratherium with a platform saddle.

As for taming it is recommended to tame quite a few mantises and have a mantis egg farm as mantises lay relativity few eggs and cannot be bred.

A good way to knock one out is to lure one into near the entrance of a cave such as the one near the red obelisk. You stand inside the cave, the golem will stand at the entrance and try to throw boulders but they cant reach inside thus you're safe. You can simply time yourself at shooting 1-2 rockets after he tries throwing a boulder at you. It is very important to aim for the head or you will kill the golem. (It took us 43 rockets using primitive launchers found in drops to knock out a 112)

HOW TO STOP THEM: u can either build some sort of cage u trap them in, or u make them get stuck between some big rocks while they are chasing u;

HOW THO KNOCK THEM OUT: u can place a CANNON (most Torpo if HEADSHOT -> u will see them shake their head if u hit the right spot -> animation!) on a paracer (first platform&foundation) and then try shooting them while they chase u -> big ammo waste as if u will not hit them while moving!; best way is to trap them, so u can even place a stationaire cannon next to the cage/trap wich makes it easier to releoad and store cannonballs directly next to the cannon, but still be aware of thrown boulders by the elemtal as they do a lot of damage -> build some kind of defense wall to avoid getting hit!

now with the right aimed cannon (i suggest at leats 3 walls of hight to place them) and the right timing u should knock them out pretty easy...
