Try to make them fall into a ravine. Flyers help with this tactic. Or better, look for some that spawned or fell into one. There’s a ravine on my SP game where there are around 11 allos that fell into it. After getting them into a ravine, kill off all but the one you’d like to tame. Proceed in taming as usual.
If you really think about it, these are SOOO underrated. Incredibly high damage and speed. A pack of 10 is easily better than a Giga. 3-4 ballista bolts, (lvl 29 btw) can make a Giga rage, and ballista bolts have a VERY long range, so... you’re dead if you’re riding it. Against a level 30 player. You see 10 Allos coming for you? Run for your ballista? 3-4 Allos dead, still 7 Allos killing you. Even rockets against 10 or so Allos? Crap. You’re still dead. They are so fast and can 20 shot ANY creature in the game if it’s an alpha. Yes, Titantos? Dead in 20 shots. (5% of the creatures health over time.) (Doesn’t work on bosses.) Compared to a Rex, an alpha Allo is arguably equal. Base stats of the Rex are 1100 health and 62 damage. Alpha Allo is 787.5 health and 52.5 damage. They have much faster DPS than Rexes and have better stamina, allowing for more overall damage. Not as much health, but still. To a wild Giga (level 1) with the alpha attack they deal 4000 damage. 4000!!!!!!!!!!
They say beaches are low resource/low threat areas right? WRONG! I used to live in one close to a cold region and some of those decided to run around the beach killing everything there. Fine, I hid from them in my tatch base and once they were far enough I thought I was safe, that until another freaking pack started doing the same. I hid my Dilo (Galinha Punk, my beloved only tame, great companion) inside the base and ran through the ocean to hide on some stones. And this was way before they cold spot me. Result: I had to hold my tears and watch in horror as they destroyed the little base I put on all my effort to build, killed my poor boy and kept going like it was nothing! Their levels were way too high, I couldn't fight them, but I was so sad I tried, died, couldn't respawn there cause I had no bed anymore, and couldn't get my stuff because they were near. Of course i waited until they went away, and of course wild dilos destroyed the rest of my stuff. I shall have my revenge!
Pretty awesome tames... It's the perfect tame between a raptor and a Rex. When I started off in a new server I could get a level 80 allo before my stone base was even enclosed properly! I slapped a saddle on that bad boy and got another level 85 allo. I now also have 3 low level carno's for the heck of it and I can defend my base without any X plants! They are perfect to kill Rex's brontos or anything not stronger than a Giga! It's pretty easy to tame once knocked out. I just fed it biotoxin every ten minutes on mobile. They're very, very, very fast. I have 145 speed and they are fast enough to not just catch up but even attack me. When trying to tame get them running through the forest. That will thin the crowd and takes away the Pack Leader buff from the high level allo. Lure it in a trap and a free Rex raptor mix is yours! Btw. Just two allo's gives you a pack leader buff on the highest level allo you have, so you know which one is gonna be my ride...
The Allosaurus is a pack-hunting theropod that's smaller but faster than Rex. When in packs of 3 or more, the highest level Allosaurus will become the pack leader, emitting a red aura and making it stronger in battle.
