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.
If you are near (safe) water, lure the ravagers in the water. They swim very slow so you can easily tranq or kill them. When they start running away, follow them out of the water and you can knock them out.
Either bola the pack and kill those u don’t want to tame (but u can’t get enough hits with tranq while bolad as it will get out) OR make a taming pen (stone) 2x2 or 2x3 foundations, 2 stone doorframes high and a Dino gate. Time it right as when they chase u, u can jump out and clear the wall. Run forward more as when they r about to attack they jump so they could get out
You don't need a large taming pen....
A 1x1 with door frames for walls. Put a ramp down on the side you will be running from. Seperate one and have it chase you. Stop at the top of the ramp. Jump down and though the opposite side door frame either at the last minute or just after it hits you. Knock it out (have 100 tran arrows just in case). Once it's out demolish the ramp, go inside and place wood spikes on four sides. Lie down inside and put in cook mutton and bio toxin/narcos. Once tamed, put on a saddle and jump out. Remove the wood spikes add a ramp and repeat.
Build a stone dino pen using fence foundations, door frames , dino gate. Then surround the outsides with stone pillars which you then use to place ceilings across the roof of the pen effectively beating the ravagers leap without the need to bola. Lure them in and lock the door behind them. Ive knocked out max level ravagers without issue using this method.
Build a 4x4 pen 4 walls high (with doorways) build a ramp on one side and get a pack to agro on you. Have them chase you into the trap and run out the doorway. They take quite a bit of tranqs to knock out, but if you use cooked mutton they require no narcotics even for a 150.
A compound bow with tranq arrows can do wonders, but I'd still have a bola or two at the ready. I'd also have a dino, preferably a high damage raptor or scorpion for crowd control, just in case a pack shows up
