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 .
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.
