Seriously it is so difficult, Any hints or tips?

On both of your party members, you may want to replace bracelets with ones that boost their main stat (strength for Lillianna, intelligence for Prancer) more than any other stat if possible. If you have higher level equips, that would also be helpful. I recommend spending 1/4 of every level-up on health, with the remaining 3/4 on their main stat (same as before). Proficiency points should be completely spent on their main stat.

Thank you, im in the middle of leveling up some of my other party members adm.

Just wish you could start over again as orginally i wanted unique colours but everything was white as lillianna was my 1st creation.
