I won many fights w/o being damaged, but never received The Untouchable Ninja - 20g achievement. Turns out I was entering these battles with some damage before-hand. Basically you need to be max HP when you win the fight and it will give it to you. I finally got it when I was fighting in the tournament, Kiba killed me in the 3rd round, I used a memoclip and came back full hp and finished him off in 3 hits taking no damage. Kind of a devious achievement. Also A Ninja in the Leaves was given to me after I fell from a tree action sequence. Go figure. I had passed 2 previously without falling.


Edit: Really botched the title :/. sorry in advance

I guess it must just be you, I recieve my Untouchable Ninja fighting a bandit and I started the battle with 1/4 of my health at the time. If you get hit at all, even if you use substitution it registers as a hit, just because you don't lose health doesn't mean that you havn't been it.

And it's bugged because you could get an enemy down to 1 hit, let them kill you and use a memo clip and the way the game is designed (bear in mind I'm a programmer and I'm guessing this) what is used to register the number of hits gets reset when it goes back into 'battlemode' so you essentially get reset really.

It would probably work like this:

if health = 0 AND memoclip > 1 then
memoclip_sequence()
else
retry_screen()

When the health hits 0 and you have a memoclip it'll go to the memoclip_sequence procedure and it would look like this

proc memoclip_sequence()
blah blah blah
blah blah blah
memotimer ends
load fight_sequence

Skipping some of the shit that would be in there, it would then load the fight_sequence with whatever it needed (details of last fight), but obviously doesn't tell it whether it has had any blows connected to your character. /end geek.

I think the tree action is the same, but if you are on the higher level and you fall to the lower level you still get the achievement.
