Make a stone foundation and 4 doorways. Lure the ravager into the trap built from the foundation and three doorways and have a friend put in the final one. Now your ravager is stuck, easy to be ko'd and protected from threats. Bolas often dont work as the ravager can still attack and cant be bolad easily after escaping.
Bola the one you want to tame and kill the others (you can bola the others while u kill 1 at a time). After u clear the junk rebola the one you want to tame and place 4 stone fence foundations in a square form around the ravager then place 2 door frame high all around make it 3 to be sure.
Use a bola or bear trap. If you’re using a bola, make sure you’re using a crossbow if it’s a high level or it will break free before you knock it out. Try finding a lone Ravager before attempting to tame.
Build a 3 by 3 foundation trap, use stone foundations then go around the whole thing with stone door frames make them two high and then put ramps all around the trap, lead them in and once they go in they cant get back out
At high levels they can take quite a few tranq arrows to knock these bad bois out. And when you bola them they tend to run away right after. So what you do is make a stone dino gate, stone window walls, stone ceilings and make a trap house. Throw a small metal trap in, run into a group, run into the cage with what one you want, it gets stuck, and boom. Ezpz
Ideally build a taming trap using 1 Dino gate and door frames to trap it (Highly recommended for high levels). If you just want to tame a level 10, 20 or something just bola it and beat the beast till it knocks out
Make a 3x3 trap using stone doorways and fence foundations. Make a ramp that lets you run straight over the top into it. Aggro them, run up the ramp and thru any of the doorways. Tame and then jump out with Ravager when you're done. You're welcome.
