I just ran a 9.5 minute battle using JMK and GMY with the health protection disk equipped against sector 2 boss (hard). How is it possible not to recover 300K health with that?
Also, i started the battle at 16/40 on the attempt to inflict potency down feat. I finished the battle with, you guess it, 16/40 on that feat. GMY attempts to apply it on every basic, and i never used any of his moves other than the basic.
