Is three shots from the master craft crossbow with tranq arrows maybe six depending on level and you’ll want to do do this on a megalosaurus with movement speed so it doesn’t kill you once out something elCome to kill it sorry something else will usually come to kill it so you want to so there’s this glitch if you cover it in fires like you put a Circle circle of campfires around it nothing will kill it right so then I like to use you just straight rummy or cooked meat and I’ll take like five minutes
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.
It will usually be very difficult to separate one from the pack. I suggest trapping all of them (usually 3 in a pack) in a behemoth gate or ramp style trap and kill the ones you dont want before taming the one you do want.
