Ok so some people have trouble taming this but I know the best way. Get a pt eny lev will do. Go to a rock golem fly where it can't hit you and can't throgh rocks at you and hit you hop off and it should be focused on the pt and jest set up the cannon alottle ways frome it so it doesn't agro to you and pelt it's head with cannon balls bam ez tame
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 .
