ive tried twice against a single bite bug. i have 100 pains junctioned to luck and tonberrys luck+50% ability but i still cant get it. first try i casted sleep and slow on the bite bug, when it woke up it put one of my characters into beserk and that character killed the bite bug before i could use the end. the second try, gilgamesh came and kill the bite bug. its as if somethings stopping me from ever seeing the end.

im trying again with selphie at 250/6000HP with high luck and aura. any other things that determine the chances of rare moves other than luck and how low HP is? ive seen full cure and wall tons of time and have seen a lot of raptures but not a single end. wish me luck.
