Ok here we go Valguero... I’m at a beach wth a rock golem oh shiz. Well don’t worry, get a tribemate, get a ptero and fly slowly away from the golem. Then... STOP FLYING! the golem will look at your friend in the air and do nothing. Now set up your cannon, but hold your shield out, because they will throw a rock at you. Then fire at will! Tamed a level 55 with 6 balls and clay. Easy raids now.
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.
How to spot them:
If you go to the mountains on SE, were golems spawn more frequently, you can easily tell golems apart from rocks as they look SANDY compared to the grey or shiny metal rocks.
In the dunes or else where the golems have better camouflage, apart from being more textured, either use a Parasaur or spyglass to confirm your suspicions.
Also if you see a rock on the horizon ‘Fall’ like creatures spawn, then take it as red it’s a golem.
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.
