this is what you wrote. i just wanted to highlight that percentages are not useful as a benchmark for healing. people with higher hp will have a higher 50% than those with less hp3. Occassionally the group will take several big hits and several party members will be put below 50%. In this situation you want to cast your Primary Mass Cure immediately followed by your Secondary Mass Cure which is usually followed by a Mass Mod Scroll if they are not 100%.
if you have to use scrolls in part 5, then you are doing it wrong
