Sad days... so I found one, took it too a safe place (my base) and then got my griffins to breed and get an egg. I made the griffin kibble and got a soothing balm. After giving him the soothing balm, all was well until I fed him the kibble, he instantly died.
As if I fed him poison. He just died, all is not lost however, I can still revive him. For 200 amber 😭
If it won’t allow you to feed it, knock it out and let it wake up then try again. Most likely due to the fact someone else tried to tame it before. Also, it tells you when to feed it at the bottom corner of your screen.
