If you've already taken on Long-arm Centipede Giraffe in the Sunken Valley, Sen'un likely won't pose much trouble. In fact, he's arguably easier thanks to the ability to land a stealth attack on him. On his own, Voldo wannabe Long-arm Centipede Sen’un isn’t a particularly tough boss, but it’s his little minions that cause the most trouble here if you’re not careful. Dealing with them can prove time-consuming, but is well worth doing before you fight Sen’un himself.

Reaching Long-arm Centipede Sen’un is a bit of a pain, but the fastest route we’ve found is from the Main Hall Sculptor’s Idol. Starting from here, run out through the doors you behind you (open them if you haven’t already) and start sprinting left back down the hill. There are loads of enemies here, but provided you don’t stop sprinting none of them should be able to hit you. Keep running and take a left near the large bonfire to follow the path down to Long-arm Centipede Sen’un’s abode.

Hide on top of the roof here until the following enemies have forgotten about you (only the dogs should follow all the way down, and can be killed by a single shuriken from the roof if needed), then drop down to the entrance. Inside are two small centipede men. Rush them down to kill them before they throw incendiary grenades.

You can now grapple up to beams in the ceiling, where you’ll find several other centipede minions. Long-arm Centipede Sen’un will be below, but won’t notice you unless you drop down. Grapple between the rafters, killing all the centipede minions up there. If you fall down, grapple back up and leave the house until Long-arm Centipede Sen’un forgets about you.

With the minions in the rafters dead, you now need to take out the ones on the floor. Move between the beams and drop to stealth kill a minion. After each kill, grapple back up to the rafters and run back out of the house until they forget about you. Don’t wait in the rafters or Long-arm Centipede Sen’un will throw firebombs up at you. Repeat this process until all the minions are dead and only Long-arm Centipede Sen’un remains. Run out again until he forgets about you. This is a time-consuming process, but it makes fighting Long-arm Centipede Sen’un so much easier.

Enter the house again and before you drop down, apply some Gokan’s Sugar as this will reduce the posture damage you take. Now drop down to stealth attack him for an easy first death blow to start the fight.

Long-arm Centipede Sen’un boss moveset

Long-arm Centipede Sen’un doesn’t have a wide moveset, instead trying to overwhelm you with a rapid series of attacks. While he’ll rarely be at distance, you should be careful of Long-arm Centipede Sen’un’s firebombs as these deal heavy damage and can cause you to begin burning, taking continuous damage unless you use a dousing agent.

To win this fight, you’re going to need to deflect a lot of attacks quickly. Long-arm Centipede Sen’un has very little posture and it won’t recharge quickly, so if you can parry and jump counter, you’ll beat him in no time at all. Thankfully the timing is quite generous here, so you can mostly just mash block and you’ll build up his posture damage quickly. Here are the main attacks to watch for:

Attack flurry: Long-arm Centipede Sen’un will swing his claws between 3-10 times depending on whether you’re in range. The number of strikes means he can easily break your posture if not careful, but equally, if you parry a few of the hits then you’ll build his meter quickly. He’ll typically follow this up with a sweep, so when you spot the red kanji, jump in the air and hit jump again to kick him for massive posture damage.

Sweep/Lunging Sweep: After an attack flurry, Long-arm Centipede Sen’un will either do a standing sweep or jump back before lunging forward into a sweep. This is the only unblockable move he has, so when you see the red warning kanji, jump into the air and kick him for more posture damage.

That’s all you need to be wary of to beat Long-arm Centipede Sen’un in Sekiro: Shadows Die Twice. He can be scary to look at, but he’s actually a bit of a baby once you get over that initial surprise and are willing to take the time to clear out his minions. Now that you’ve beaten him, you need to make sure you’ve bested Genichiro Ashina to progress much further in Senpou Temple, but you could also head to the Sunken Valley and take on Snake Eyes Shirafuji instead.
