On 5X mature rate, it takes 9.6 days to fully mature. On 5X hatch, it takes roughly 10 hours I believe (I just hatched one recently and forget) with a 5(?) hour wait between breeding. On official, this number soars up to 48 days, 5 hours. With a 4 day wait between breeding.
There are 3 ways to gain respect 1. Change your name to the last letters of the griff family 1/17 of griffs will have that last name (look on YouTube or something else for names) 2 wear the royal crown, this shows that your the king or queen and will gain respect of any griffs. And 3 you need to be lvl 85+. If you do KO one without respect it will refuse to eat. Happy taming!
