Though it was possible to defeat Muzh on a level 3, Willow did have sword control as weak as he did when battling Bogarda. Basically, one sword swing inflicts three hits to a boss. In addition: Willow was 10 ex. short of the next level, and limited HP made him a ticking time bomb. The reason was that 32 hp was not enough to squeeze in a hit from Muzh to go temporarily invisible. Thus taking damage to try to save some time.
In my 4th draft, Willow was able to do such thing and squeeze in a hit to finish Muzh off. But here, I fear that I wasted a number of frames trying to defeat Muzh on a lower level. The route toward Muzh's room, where certain encounters were mandatory and could not be manipulated, might be the problem in this case.

I'm using fceu-rerecording-0.98.28. The FC5 goes into the "fcs" directory. Load the movie as read-only and hit F5 to load the save-state, or you can watch the progress. ^_^
Edit #1: As I studied both drafts, on the very frame that Muzh was defeated (right where exp. started changing), I only saved 25 frames! It's frames 85630 on the 4th draft and 85605 on this one. Doesn't look much, but as I said, this is a tweak using everything we know. I think now we're in business! ^_^
