Have a ton of hi-lv Dilos on neutral follow a hi-lv Raptor or similarly sized ride-able Dino on aggressive/wander, the effect is devastating for an opponent. Add Dimorphs for aerial support for PVP raid guard squads. The more the merrier, and breeding Dilos enmass becomes worth it.
1.kill some dilos, dodos or compy so that you can collect meat.
2.Craft a slingshot, wooden club or you can beat it with fist (If your trying to knock it with fists choose a low level one; if with slingshot collect a amount of stones first also remember wooden club breaks fast so craft and keep atleast 3 more wooden club for backup)
3.Find a dilo
4.after it's unconscious open its inventory by going near to it and tap and hold. After you need to put some meat which we collected at first
5. Wait.....if your dilo eats all the meat but still not tamed put some more meat to its inventory and wait......
