But yeah, that proves there IS a holy element, but it's extremely hard to get holy.
thats why u save one friend sphere and one return sphere, and dont use ur lv. 4 sphere just yet, if u have one. when rikku gets close to holy, use the lv. 4 sphere and learn holy, then send yuna (via friend sphere) learn it, and return (sphere) no to hard. or u could do what i did and fight her with physical attacks only. a lot harder
