Was this a glitch?

It also could be the equipment you were wearing. It could just have no effect due to what you had on.

Well when I fought the same enemy shortly after, with exactly the same magic junctioned, I received damage from the move.

I'm gonna test it with float (so it misses) and then see what happens.

I tried out the above, and it did indeed say 'Miss'.

So that's that answered.

So it was either:
a) a glitch, or
b) it did take energy off but I just didn't see/notice

I'm pissed off now. Because it feels like I've cheated. Argh. Now I wanna delete my file but I don't want to at the same time cos I would have wasted my time and efforts if I do.
