I was sitting on a flyer on a cliff above the deinos, thought I was safe to wait for my moment to steal their eggs...had the biggest heart attack when one of them decided to climb up the cliff. I accidentally dismounted in shock and fell right into the packs claws, where they shredded me to death. Don't be scared of them, they smell it.
So I was ready to get one of these guys so I get my stuff and snatched some eggs as I leave I hear that intense battle music I get on my Rex thinking nothing of it I get lost I can’t believe it and what do you know my Rex is losing health quickly I look behind it and LOOKS LIKE THE WHOLE FAMILY DECIDED TO GIVE US A HUG GOODBYE about 4 of em where there my Rex died :( I did too I lost all my precious belongings please return my stuff family of Deinonychus.....
You cannot outrun these so you must use stealth. When near the nest you must crawl around and use objects to hide yourself from the full grown ones. Secure the egg and get the hell out of there and make sure to run away by running behind objects so it slows them down.
These guys are idiots. Many of them spawn on clifftops. Just bring in a flyer (Argies or Pteranadons will do just fine) and take a swipe at them. They will all zero in on you instantly. Kite them right off a cliff. Do a smug slow-walk as you claim the eggs in complete safety.
