If you are unsure if a rock is a disguised golem or not, a spyglass shows their name and level even when disguised. Also, when disguised, the rocks often move slightly as you get close, re settling onto the terrain.
Rock elementals are extremely tough to kill or knockout. Over encumbering them inside or around your base and setting them to aggressive allows them to defend your base with their rock throw attack without being kited away by enemies.
There is a great little natural passage that you can kite the golem in to at 64.1 - 49.9. We tame all our Golem there. They can't get out but once tamed can be moved out. It offers a great firing position for your cannon.
PRO TIP: on 2x taming weekends (Evolution Events) on official servers. You can knock out a level 20 or below elemental, slap some sulfur in it, and call it a day as it will not require narcotics on 2x but WILL still take 4 hours.
All rock elementals have the same rock skin when disguised. It is a bright yellow boulder and is very noticeable against dark mountains. Keep your distance, as they can aggro on to you when you get close.
Build 5 stone dinosaurs gates and place them beside each other they should snap... now remove the middle and drag a Golem and lead it in the middle section.. now the Golem is stuck the paracer should be holding the cannon or any KO weapon face the cannon to the Golem and start shooting its head if the Golem is aggro on the stone gates go up to it until he losses aggro and focuses on you grab a shield so it will take less damage while it throws rocks at you the Golem can't run away because the two gates are holding him... hope this work make sure to carry extra ammo for the weapon if you miss the head
Try kiting it into some rocks. Best way to do it is to use pillars three high so he can't get passed them maybe six or seven wide. Park your parcer about six foundations away and place two more sets of pillars behind the parcel three high to block all rocks thrown. Fire away
Incase you didn't know, rock elementals take headshots. If you hit anywhere else it doesn't count. Don't waste your cannon balls. If you can't get it straight on, aim lower because aiming higher isnt normally within its hit box.
If you're looking to slay one of these beasties, here's a clever way. You and a tribemate go out on an argentavis, one of you is driving, the other is attached to it via grappling hook with a rocket launcher and a good amount of rockets. Tried this with one of my tribemates and we had a blast.
If our tribe goes egg-stealing, we always have at least two tribe members on Golems at the edge of World's Scar. When he stealer flies away, the Golems agro the wyverns and kill them all (immune to elemental attacks) for TONS of free milk
Build 5 stone gate frames snap them together at a 45 degree angle remove the middle one have some on a bird get aggro when it's in the trap and unload with cannon as long as bird is in the air it will just stand there for you to Ko. And it will not throw rocks at bird as long it is flying. Just don't hit bird with cannon.
