Always have bolas ready. They won't be for the Rock elemental, but for your tribe mate(s).

Run.

Be friendly and caring when engaging this peaceful creature. He may disguise himself a rock, as he is very shy. Use stone to passive tame this gentle giant.

Dont try to mine this thing.

It eats rocks...
it’s a rock...
CANABALISM

Wiki says: To tame it, you need brute force like a rock straight into its head.
Billy (tribe of billy) - lvl 2: Will my Journeyman slingshot work? I just spawned here and i was told it eats rocks! I have some in my pocket! I WILL TAME IT

Remember when mining: In Soviet Ark, Rock Mines YOU.

It's not just a boulder... It's a rock!!! The pioneers used to ride these babys everywhere

Tamed with stone once ... Still taming the same elemental
