This will be a mount to take out any enemies it will beat up those guys who always are raiding you. I have one on server 10 that I transferred over and I rule all. If you don't use mantis kibble it will take a lifetime to 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 .
