Want cheap best way (imo) to tame this? Well get yourself a flak chest with a parachut, cross bow with grapple hook and a lvl 5 argy. Once you have the blood, just have your argy fly, grapple to your argy then whistle it to fly up and fly high up in center of bog, keep flying around and pretty soon one just grabs you from far and you tame it. Got 7 already day 1 (irl) official.
You can use baby oviraptors to pick up your bloodstalker eggs, and then the baby oviraptors die their body time is the same as the egg incubation timer so you can drag the egg anywhere until it hatches.
