When attempting to knock it out, create a four by four by four metal structure it’s a metal gate on one side. Position a cannon as far in the back as you can. Make sure that you have a cross section across the gate so that the golem can’t hit you with boulders. Ready! Aim! Fire!!!!
It's a bit silly that kibble tames it a lot better than rocks or sulfur because even in the dossier it says that it lives off of absorbing nearby rocks and minerals. So mabey they should make it so you have to feed them a rare mineral like obsidian what if they made it so you could tame one fast and with high effectiveness by giving one a few hundred or few thousand obsidian . or what if there kibble was made out of a combination of ores and minerals .
