Lystrosaurus is almost entirely useless, but can provide a slight exp boost for you and your tames so here’s a guide to help you tame one.

1. Lystrosaurus are found all over the beaches and many grasslands of the islands. They can be perfect tamed with rare flowers or mejoberries and require very few of either a few rare flowers or 20ish mejos for a lvl 150. I would not recommend using normal berries since you can gather enough mejos at any stage of the game for higher effectiveness

2. Lystros are a passive tame and very slow which makes them very easy to tame. The main danger you will need to watch out for is carnivores like raptors or dilos that will attack you or the lystro and complicate the taming. To avoid interruptions, you can kill all nearby hostiles, or carry it to a safe location.

3. Once you have prepared simply feed it your food of choice every time it is hungry until tamed!

Happy taming!
