Long-arm Centipede Giraffe is a boss in the Sunken Valley region in Sekiro: Shadows Die Twice.
Logically, his methods of attack are completely identical to Long-arm Centipede Sen’un who is found in the Senpou Temple region, so your method of beating him is the same. Of course, depending on the order in which you’ve decided to tackle each region you may not have encountered Long-arm Centipede Sen’un yet, so if you can’t be bothered to click that link and read up on how to win the fight then I’ll explain for you again right here.
Long-arm Centipede Giraffe is found in the room right next to the Gun Fort Sculptor’s Idol in the Sunken Valley. This is great news because it means if you die you can get straight back into the fight quickly. The Long-arm Centipede bosses are actually very easy to beat, so you shouldn’t have to have too many attempts, but you won’t have far to travel if you do die a couple of times. The main difference with Long-arm Centipede Giraffe compared to Long-arm Centipede Sen’un is that you can’t sneak up on Long-arm Centipede Giraffe to get rid of one of his Deathblow marks with a stealth Deathblow, which makes this fight the trickier of the two. The only option here is to get up close and personal and beat him twice.
Head into the room and he’ll come straight after you. He attacks so quickly that you’ll have no time to get any hits of your own in, so the key to winning this fight is to break his Posture without attacking. Forget your attack button altogether until you need to hit a Deathblow, this isn’t the fight for attacking.
Long-arm Centipede Giraffe will run straight at you and start swiping his claws at you like a mad man. You need to Deflect all of these attacks and you’ll start filling up his Posture bar quickly.
When you Deflect a full combo, Long-arm Centipede Giraffe will back off. This means that he’s coming back in for his Perilous/Red Kanji attack, which sees him swing both claws inwards in a pincer-like movement. When he does this, jump straight in the air and jump again when you’re above his head to perform a Jump Kick for some more Posture damage.
When you land he’ll go straight back into his swipe combo, so start Deflecting again and you should open him up for the first Deathblow.
Nothing changes for the second part of the fight, so simply follow these steps again and you’ll soon open him up for the second and final Deathblow. It’s really that simple.
Killing him will bag you some Yellow Gunpowder, a Prayer Bead, and some exp, and you can drop into a hole that gets you underneath the floor where you can find some more goodies.
