This Complete Isshin, The Sword Saint Boss Guide gives you strategies on how to beat Isshin easily, as well as tips, tricks and lore notes.

Isshin, The Sword Saint Strategy Writeup
Phase 1: He will start as Genichiro, Way of Tomoe. The fight will be pretty standard as the 3rd phase near Kuro’s room on the rooftops. Aside from the big, black Mortal blade swings he starts with. You can dodge behind him during the first swing and get easy hits in, staggering his second set of swings. He will lunge, and with enough distance, Mikiri counter makes this fight simple. He only has one Vitality bar, and once you deathblow him, a cutscene will play as Isshin steps out of him.
Isshin Phase 1: He will start a decent distance away from you. His main attacks will be a rather quick. One of his main ones being a double slash with considerable distance. He will sheath his sword and it will flash white, then he will dash and double slash. Deflecting both attacks is an option however, you can run backwards and sprint to the side. Once he slashes he is open for a quick two hits. His main slashes are a three to four hit combo, delaying between each hit. A thrust for an easy Mikiri counter, which will be telegraphed as he will end up in the thrust position before committing. Along with these attacks, he will do a long range wind attack, which can be dodge by running sideways as you can get a couple free hits on him this way as well. And a close range, full screen sweep, giving you just enough time to sprint backwards before it goes off. Once you get the deathblow in phase 1, he may continue to attack for a second before stomping the ground to begin phase 2.
Isshin Phase 2: Phase 2 is a massive difficulty increase from phase 1.Once he stomps the ground, he will do knockback damage, but not Vitality damage. Pulling a spear and swiping it in a tight circle around himself. If timed correctly, you maybe be able to get a hit or two in before he begins his assault. Along with the spear, he will have a short sword with him, along with a matchlock pistol he will use this to fire several rapaid fire shots. During this phase, he will keep the wind sweep attack, using it randomly throughout the fight. He will be consistently more aggressive, moving towards you if you make too large of a gap, firing the pistol if the gap gets too large. Making a large gap, you may be able to bait him into using a thrust that can easily be Mikiri countered. He will do large, heavy hitting overheads, usually one after another that can be deflected at the cost of heavy posture damage. Dodging sideways as he descends from the overhead, you can easily dodge the hit and get a few hits in yourself. After Isshin deflects one of your blows, sometimes he will jump backwards and make a sweep at you with his spear. Right as he does this, dodging into the attack (towards him) will allow you to get several hits on him as well. Be careful doing this, as he may do another overhead directly after. Dodging can keep distance, as much as he may spam the gun, is the easiest way to bait him into thrusting, easy overhead dodges, and breaking his posture overall. NOTE: Using the Loaded Umbrella will save you from taking ANY vitality or posture damage if you are struggling to dodge/deflect some of the perilous attacks (unless he is using lightning, which doesn't come until phase 3) AND Isshin will take considerable posture damage if you are using the umbrella to deflect!! You can use the umbrella to help cheese your way through if other means are not working for you. Deathblow on this phase will move him into phase 3.
Isshin Phase 3: Almost the same as phase 2, except he has three new attacks. One being a large swing, in which he covers his spear in lightening and swings it at you. You will want to get close when he does this and jump, as to deflect it directly back at him for big Vitality and posture damage, along with a flurry of free hits. His second attack will be similar to his phase 1 long range wind attack, the main difference is instead of it being vertical, it will be more of a distance slash attack. Third new attack will be adding lightning damage to his large overhead attacks. You can deflect the lightning, although the timing can be difficult. Strategy will be the same as his phase 2 fight. Bait out the Mikiri counter along with his lightning attack, and this phase should go smoother than phase 2. Upon giving him the final deathblow, do not miss the Mortal Blade deathblow, or you will have to go at his third phase again.
If you defeat the boss you will see the writing "IMMORTALITY SEVERED" upon the screen.
Isshin, The Sword Saint Attacks & Counters
|Charged Attack, Vertical Force Wave||Isshin puts his sword back into the sheath and readies a stance. A glint will show on the hilt. After a delay he will strike downward with his sword, launching a wave of force infront of him. After another short delay a second wave of force will be launched forward following the same path.||Deflect, then dodge second force wave. Waves can be deflected fully but will leak damage if blocked. It can be interrupted by a full charged strike of praying strikes exorcism.|
|Ashina Cross||Isshin puts his sword into its sheath and after a short delay steps forward towards the player and makes two very quick slashes with his sword.||Press deflect twice without pause as soon as you see a flash of light at his hand. If trying to avoid this attack entirely, be sure to run as far as possible.|
|Ashina Cross Cancel||If the player is very close to Isshin when he is readying "Ashina Cross" he will cancel the attack by quickly smacking the player with his sword, then following up with a perilous sweeping attack. He will also do this after the player repeatedly deflects his attacks.||Deflect the initial hit then jump and stomp. Block or attack when coming down as he will counterattack immediately unless forced to defend.|
|Ichimonji Double||Isshin will raise his blade in a ready stance and perform an Ichimonni double. If the player deflects the first hit Isshin will stagger, then immediately transition into "Charged Attack, Vertical Force Wave".||Since "Charged Attack, Vertical Force Wave" is far more difficult to deal with, it is best to simply dodge or block this attack. The attack can be sidestepped, by doging to one side of Isshin.|
|Distance Slash||If the player is far away from Isshin and/or uses an item Isshin quickly dash at the player and slash them.||Make sure that you are far enough away that you have time to react or that it simply cannot reach you.|
|Charged Attack, Horizontal Force Wave||Isshin will sheath his sword and charge an attack. After a short delay he will quickly swing his sword in a spinning motion causing a large force wave in a circle around him.||Wait for a moment, then deflect as soon as Isshin begins to move his arm. Alternatively, you can instead sprint and then jump toward him, then jump again on his head. This will allow you to get 2-4 free hits on him as you descend from the jump and after landing, and his slash will not hit you since you're in the air. Alternatively if you are close, it can be interrupted by a full charged praying strikes exorcism.|
|Charge Attack, Double Projected Force.||Isshin will sheath his sword and charge an attack, After a short delay he will make two slashes in the player direction launching discs of force with each slash.||The discs will deal damage through your block in not deflected properly. The attack is easy to dodge and it is recommended you do so as deflecting the discs will not affect Isshin's posture.|
|Leaping Slam||When far away from Isshin and/or using an item Isshin will leap into the air and slam down with his spear. He will then follow up this attack with either a sword strike or he will pull out his gun and shoot at you.||Deflect the slam then counter attack. Regardless of what he does after the slam he will either get hit or block your attack.|
|Retreating Sweep||Isshin will leap backwards into the air and sweep in front of him with his spear. He usually does this after blocking/deflecting several of the player's attacks.||This attack comes out very quickly and is difficult to deflect. Deflect, or quickly dodge forward for a free hit.|
When at distance Isshin will pull out a pistol and shoot at the player several times, he will often then follow up with a large thrust from his spear.
|If simply blocked, the bullets can damage your posture very heavily. It is recommended that you learn how to deflect them (it should be noted that the last bullet is slightly delayed so caution should be made not to get your posture broken). Mikiri counter the following thrust, or jump attack if it's a sweep.|
All attacks from phase 2
He will jump into the air and lightning will converge on him. He will then launch the lighting at the player with a sword swing.
|Jump into the air and use lighting reversal, mist raven, or Sakura Dance to redirect the attack at Isshin, this will stun him.|
Isshin, The Sword Saint Lore
- The reason why this younger version of Isshin appears is due to Genichiro using the Black Mortal Blade on himself, as a sacrifice, to bring his grandfather back from the underworld. As described by the Black Scroll key item, the Black Mortal Blade: "is said to hold the power to open a gate to the underworld. It is through this power that it creates life."
Isshin, The Sword Saint Notes & Trivia
- Voice Actor: Andre Sogliuzzo (English), Tetsuo Kanao (Japanese)
- The Japanese honorary title of Kensei (剣聖) is only given to a warrior of legendary skill in swordsmanship. The literal translation of kensei is "sword saint", which implies a higher degree of perfection and moral dimension than the more commonly used "sword master" (剣豪, kengo). The title is not to be confused with the term "swordsman" (剣士, kenshi).
