When they leap at you it's hard to see where they go, I recommend finding a corner and staying there until it leaps then bola and either kill or knockout. This always works for me when I'm trying to tame one but another tip, just stay out the swamps
I was playing SE with my friend,2 jerboas,2 raptors and a new direwolf when the jerboas predicted a lightning storm so we built a storm shelter and afterwards my friend was riding around on the direwolf while the raptors were following her and she accidentally fell into the green obelisk tribute terminal area and we got swarmed by like 15 of these and one of the raptors got killed and the direwolf drowned and now my friend is sad
Screw these guys. I hate them, i hate the mothers that birthed them and i send them to hell. They have killed me countless times and i think ive killed, nope cant get close enough to kill them. If spotted run, run far and run fast. If you spot one while turning a corner and its just there 20 ft away start crying and hope it didnt see you.
Be careful when traveling through the swamp, they can launch at you and drag you into the water. If you act quickly, with either using a Bola or Attacking, you can escape. A high level one will be extremely dangerous if unprepared.
