These things are op for me (a noob) so heres how I got it

1 can find raptors use mission/task hunt raptor it will take to an area full of them

2 bola them and knock them out using fist,traqs,slingshot (what I used)

3 feed kibble or meat the dododex will tell you

Also protect it from dying

And bam you have a raptor

I use ark mobile and I am a noob/new player so there may be better way that I don't know
