Question about items

Hi, I was wondering how mutch it would cost to max a knight + get the best Tire items in the game, And have some extra life potions over, Thank you

Knight tops are like $1 to $1.50 so 3 tops + 1 exa hp/def would be another $0.50.
Maxing a 6/8 knight would be ~$20 so you would be looking at around $23.50 to $26
Hope this helps!
