So I just tame an Allo solo. But it don't careful planning. You must first be willing to die a few times but at the end it's all worth it. They're always in groups so the first step is to lure them away from each other. The best way is to make one follow you and run towards a hill or cliff where they can stay. If you gain the high ground use a crossbow to damage one. It would eventually run away. Have at least 30 tranq arrows. It can surely take a beating but usually with 18-24 tranq arrows would KO it. The good thing is that since it's an allo, other allo's won't eat it or attack it
