Bola them first and tranq dart them, anything above lvl 35 will take more than 1 bola lvl 95 and up is going to a struggle if you’ve just spawned in, but great travel mount and great in combat just pump health and melee, stam doesn’t drop that much, similar to a thyla
You won't find anything more useful for keeping these guys still than a small bear trap. You can Bola and kill the other ones if it is in a pack but keep the high level one trapped for knocking out once you've killed it's pack. Up vote for other people
Build a 4x4 pen out of stone doorways that is 4 high with a zip line coming down into it while a ravager is chasing you get on the zip line and go into the pen it will follow you then run out the doorway and knock it down when tamed you can get it out by climbing back up the zipline
Make a taming pen with a ramp and lure them into it. Make sure you have tons of narco arrows and multiple crossbows particularly if there are high-level ones. À 115 took me nearly 50 arrows.
Cooked mutton tames them the best.
