Diplo kibble works like a charm. If you want to tame an Allo relatively fast and easy, follow these steps: Tame at least 3 Lystrosaurus’ (2F/1M) and have them lay eggs/breed. Make Lystro kibble (it usually takes about 2-3 kibble) in order to tame 1 female Diplo (or 1F/1M to breed). Have the Diplo lay eggs and make 3-5 Diplo kibble (no meat required, but you’ll need rare flowers). Find a pack of Allos, lure one away (or if you’re strong enough, kill off all but 1 or 2) and knock it out with darts. Put the kibble in its inventory and welcome your new tribe member ^_^
When single taming be at least level 52. Tame a Tapijara. Find a group of allosaurus. Next break one off from the pack by attacking one and leading it away. The others might follow that’s okay. Lead them to a cliff and fly over the cliff. Switch seats and begin to tranq the one you want. When you knock it out lead the others away. Go back to the unconscious Dino and begin to place meat in. Have at least ten Narco per level. The other allosaurus will almost always come back. I suggest taming two at a time. Knock out a second one. Then kill the rest as they might attack your brand new allos....... keep in mind that prime meat speeds it up by 70 percent than raw meat so go and kill some Dino’s. Good luck and happy taming! Also they might kill your new tapijara so make sure you have at least 50 percent health when going close. They killed mine.... but I had three more. Always have a backup flyers.
