Hi, I tamed a level 3 female, and none of my tames died (I tried something like this months ago and lost a couple of my tames) first, make a 3x3 stone floor on Griffen mountain. Then on 2 sides make a 3x3 wall each. Then at back make 3 walls high on row 1 and 3. If you fill it right up, your tame has no where to go. Now you need about 4 or 5 allo kibble if you use a 15x soothing balm. You get something like a pter with a saddle and you need some tranq arrows and bio toxin arrows, and of course nacrotic. You need to lead in a griffen that respects you, then you fly out the back because they can’t fit threw. Then you have to get off your pter and place walls where the griffen came through. Make sure there is no 2x2 space in the wall or else it will get away. Once it’s trapped go track to the back, and then shoot like crazy at the griffen, and now you have knocked out a griffen. This worked for me, but it got out of cage first time because I was to slow, I got it in again and I k.o it.
