For those who are confused about the 2nd tier ritual, as it was previously commented it uses the potion of the character, but it also uses one of the tier 1 ingredients used in the 1st tier ritual , and a 2nd tier ingredient whose description which relates to the character.
As an example the Fox tier 2 ritual uses, tier 1 orange crystal, the 2nd tier Tasty Drumstick which is, "Delicious for animals and humans alike", and of course the fox potion.
