There’s a relative lack of animal life near the blue zone entrance at 33.6 Lon 61.4 lat. Use a karkinos to grab the wild one you want (if you’re at that stage) and kill everything in the area. Yi Lings have severe ADHD and will attack ANYTHING with a pulse even if it’s far away from you. Build a circular foundation using 6 triangle foundations and stack 2-high doorways around the circle to make a trap. Stand in the trap when it divebombs you, which will lead to it getting stuck in the doorway for an easy stun. Bring 3 sets of flak and some medbrews, and at least 20 biotoxin for high levels. If you can, have a tribemate constantly going around killing wild dinos to prevent the yi lings ADHD from triggering! (I’ve done this solo so it’s perfectly doable)
