A good use on pvp servers is to have them in rock form hidden around metal nodes or other resources, to stop other players from taking them.
Up if you think there should be a fire elemental
Who else thinks there should be little pebble golems that can cling onto your back tamed and work as armour?!
Rock golems should have reduced weight for stone come on wildcard
Store your loot on one underwater in rock mode, no one will ever find it
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 fire elemental. It's on genesis
they should make it so when its hurt and you put stone in it it does this cool animation where it repairs/heals itself will the the rocks rarer minerals repairs/heals itself more
Use golems as a place to put stone, they carry alot and will eat it when hungry
Rock Elemental can take a lot of hits reducing damage by 50% from all non-blunt damage. A TAMED Rock Elemental can NOT fight a wild one. It works the same as a Giga so I would advice against it.
