I will say to the easiest way to tame a Griffin. But for this you should have to sur name of the Griffin you can change you name with a name changing ticket.

1.find a Griffin which maches with your sur name (the last 3 letters ex: lot, go, no, mtt etx) it should be a low level.

2.get a 10X or 15X smoothing blame and at least 3 to 5 all kibble

4.get more than 100 bio toxin

5.wait until it's torpor is at very low and then feed it 100 bio toxin.

6.after some time give it smoothing blam and allow kibble.

If it helped you plz like.
