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.
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
