PRO TIP: on 2x taming weekends (Evolution Events) on official servers. You can knock out a level 20 or below elemental, slap some sulfur in it, and call it a day as it will not require narcotics on 2x but WILL still take 4 hours.
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 .
