To tame it , you need some type of narcotics ( biotoxin , narcotic , narcoberry , etc) and alot of plant Y flashbangs. When it notices you it will start flying around you while simultaneously throwing feathers at you .

A little counter for those feathers will appear were normal buffs show up . When it’s high enough , the Yi ling will dash at you , and you need to throw a flashbang when he does so .

He will be stunt for a short amount of time , and during that , you can feed him narcotics for it to gain torpor. Continues doing that to knock it out.
