I also just defeated the headless guardian ape and did not get the ninjutsu. Is this correct?

didnt get it either. bug?

Not the first time around, you fight him again unfortuneately

You get the Ninjutsu when you fight him the second time in a different arena (in the cave behind Snake Eyes Shirahagi in Ashina depths). This time he'll get a waifu during p2

this page incorrectly calls "Headless Guardian Ape" the source. There are two encounters, one called Guardian Ape, the other called Headless Ape. Check Headless Ape page for information about the second fight.

After you defeat the 2nd headless ape make sure to use the skill mortal blade on its corpse an you will get a execute option on the centipede getting the ninjitsu <

You must also have the mortal blade for this! (taken after the 3 monkeys boss)

It's not go back to the dead body and walk to the head

Just go to the body, press your r1+l1 to use your mortal blade and execute the centipede. Then you'll have your bestowal ninjutsu

Yeah, I will have to kill it on NG+ to get it. Information the Mortal Blade should be mentioned in this article.

When you fight the headless ape the health bar still says "Guardian Ape."

And then when I leave the game and come back, the dead ape and the centipede redrawn at the same place. No matter how many times I kill it, I don’t get the ninjitsu and they despair...

I was having the same problem. Then I traveled to the Poision Pool bonfire and went back to the ape arena on foot. This time I also held down L1 + R1 rather than tapping them. It gave me the ninjutsu that time. (Not sure it was the "go there on foot" part or the "hold down L1 + R1" part that did the trick.)

quit game then cont

have you killed the centipede inside headless ape neck?

Hi no you can only have one weapon buff active. Living force, divine confetti and bestowal are mutually exclusive and spiral cloud passage cause really low ampunt of damage.

using living or projected force with confetti buff active, will overwrite the buff, so after performing projected force with lilac umbrella for example, end the effect on the blade

only this sword feeds not off blood, but instead demands great dexterity.  Lady Maria was fond of this aspect of the Rakuyo, as she frowned upon blood blades,

I say it adds style damage (except not really, but cmon it looks cool)

It adds life steal, and using Bloodsmoke on them creates a healing cloud

Did you finish off the monkey in the second fight with the mortal blade? If you don't have it the monkey just ends up laying on the floor kinda pulsating because it's still alive. Also if that's the case, after you kill the money in the second location if you go somewhere else and rest then one of those schimochi warriors will spawn in that arena which is the one that gives malcontent's ring.

Roughly 28 seconds after timing it 5 times on several different enemies
