You have to level 50 dragons containing your targeted element(s) (hybrids count toward all of their elements) to level 10 to change the shrine from bronze to silver, then you can raise then to 15. Get 50 level 15s and you change the shrine to gold and can then level to 20. You don't have to have them all at once, but you can't get a dragon above 10 unless the apllicable shrine(s) have been leveled.
