I. Preface

Bosses for the most part are pure RNG rather than consistent. Do not be surprised if your boss' fight suddenly becomes extremely slow. Later on, I will be listing and post it's footage on both mode Normal and Crazy.

Medusa

Appears in Garden Forgotten by Time

Patterns

• Snake Punch Medusa will hiss, then swing either the left or right snakes at you. If she swings her left, she may also swing the right immediately after. Dodge by double jumping and whipping.
• Stone Gaze Medusa will yell "Turn to Stone!" then fire a beam from her eyes, turning Leon to stone briefly. If Leon doesn't break out of it faster enough, she'll follow it with a Pinball. Dodge the same way as with snake punch.
• Pinball Medusa will say "Just as I Thought," then start rolling around the room, bouncing off any walls she touches. Medusa is completely invulnerable while doing this. She can also choose to randomly do this.
• Cursed Blood If Medusa cornered then she will float toward the center of the room, dripping Blood from her eyes. Touching the blood does damage. It's pretty much free damage when she does this.
• Summons Only usable when Medusa is below 50% HP. Medusa will yell "Summons!" then float up into the air, facing downward. She'll spawn many tiny snakes, which will crawl quickly in Leon's direction, doing damage if they connect. Dodge by jump whipping and throwing Axes.
• Rock Shower Only usable when Medusa is below 50% HP. Medusa will yell "DAMN YOU!" then summon a number of small rocks, which will revolve around her. After a short time, she'll fire the rocks at Leon. Dodge by running behind her, since the rock's trajectory won't allow them to hit there easily.

The best combo here is Axe-, △ ^x3,-Axe . Technically you could keep up this combo indefinitely if she never attacked. You make sure that you wait until you have a combo going before using Rubies to increase the damage. You may end up squeezing an extra Rubies' worth of damage out of them.

Joachim

Appears in Dark Palace of Waterfalls

His attacks are not worth mentioning as he only gets 3 off

• Use a Ruby to clear out the Orbs which power his shield. You have to whip him once to destroy the shield. △, ▢, ▢, △, △ is they way to go since you have to keep him stunlocked when he normally would be moving around.
• Svarog Statue running helps to keep the combos going, since you need a high combo to dish out the damage necessary to kill him before he reactivates the shield.
• Michael's Sword and Rubies are the primary damage source here. Joachim is weak to the Cross, which makes the initial hit do about 120 damage. The smaller hits afterward add up to another 30-60 depending on how long he sits inside it.
• Rubies do 56 base damage to him, but with high combos do well over 100, which is just chunks out of his HP. The whips in between his attacks are simply to keep him from moving around too much, causing my combo to drop. You can accept any fight that kills him before he gets his shield back up.
• Note that sometimes Joachim will reactivate his shield early, which is a run killer. He can also not attack and just keep flying around, which is the same end result. On top of that, the Svarog Statue provides enemies with a small invulnerability period, which occasionally causes Michael's Sword to do no damage. This guy is easily one of the biggest run killers.

Golem

Appears in Anti-Soul Mysteries Lab

He only gets one pattern off, and it's a scripted attack. This fight is easy for the most part

• Phase 1 gets Holy Light. This can double hit if used at the right angle. That first shot of it has a VERY precise angle in which you can double hit him. The whip is actually necessary to be able to 5 cycle him.
• You need 5 hits each cycle to be able to get him down in 5 cycles: 2 hits from Holy Light and ▢, ▢, △
• Once Phase 1 is down, spam Quick Step a bit since you need Quick Step 2 for Death. you need 10 uses of Quick Step to learn it. Using it here costs no time since you're waiting for
• Michael's Sword and Rubies are the primary damage source here. Joachim is weak to the Cross, which makes the initial hit do about 120 damage. The smaller hits afterward add up to another 30-60 depending on how long he sits inside it.
• Phase 2 is the reason for conserving Rubies. Launch a Michael's Sword, both for damage and the combo booster, then spam 6 Rubies until it dies. That first attack it does is scripted - It will always be a Circle Punch. This guarantees that you'll have enough time to kill him before his second attack.

Undead Parasite

Appears in House of Sacred Remains

Patterns

• Fire Breath The Dragon will stick it's head out of a hole and breath fire over about half the room. It will swing it's head from side to side to cover more area with it. Dodge by either Quick Stepping through it or just don't get near it.
• Dragon Charge The Dragon will fly out of one of the holes and charge around the room in a circular pattern. Dodge by keeping away from it.
• SoullessThey move around underground and only surface to attack. They're pretty weak, and are more of a nuisance than a threat. The Soulless in phase 2 are faster and stronger.

Holy Water is key here, especially for phase 1. Cross Blazer allows me to hit two eyes at once, and with Black Bishop active, takes them down in 3 uses.

Between phases you learn Quick Step 2, since it doesn't cost time to do it here, just like with Golem. Phase 2 is a bit tougher. Use Roaring Flames and action cancel into whip combos to keep the combo going. Roaring Flames does pretty significant damage, especially with Black Bishop and a decent combo going. You may have to keep dropping the combo, though, since the Soulless can knock you out of my combo if they manage to hit you, and that would allow Undead Parasite enough time to move, which costs a LOT of time. Additionally, the Dragon breathing fire in phase 2 costs time as well since it becomes impossible to get a combo going with the fire in the way. If it does that, use one Roaring Flames to get Undead Parasite to move immediately, then finish it somewhere else.

Succubus

Appears in Ghostly Theatre

Patterns don't matter since we just tank 90% of the hits anyway. Force Cannon + Black Bishop is a godsend here. It does 81 damage per hit, so 13 hits. The problem is that she will randomly yell "No Tricks!" and negate one of your attacks and anything immediately following it. That's the whole luck factor to the fight: her not blocking too many of your shots.

doppleganger 2

Appears in Pagoda of the Misty Moon 1F

His attacks don't matter.

The idea is to finish him off in one combo, but this requires a bit of luck. Satellite is one of the only subweapons he won't guard against, plus it knocks him around a bunch. That's a problem as well as a blessing. It makes it very hard to keep a combo going since it's very easy for him to get knocked out of range of Satellite. It's possible to get him down in one long combo. Only use 3 hits for the first combo since you want him as close as possible, and Draw Up works extremely well for that. The Quick Step is to cancel out of the whip animation and allow you quicker access to Rubies. Cross Blazer is a much safer method, but it's too slow.

Walter

Appears in Pagoda of the Misty Moon 2F

Walter's attacks have no bearing on the fight. He only gets to attack once if the fight goes correctly

• Walter has one major luck factor that can make or break a run. His first action has to be anything BUT a teleport. If he teleports it's an automatic 20 second loss.
• Start off by using Spirit Ripper and activating Black Bishop during it's windup animation.Then you can choose one of these strings:
• △, ▢, ▢, △, △
• △, △, ▢, ▢, △
• △, △, ▢, △, △
• The first theory of Draw Up not being able to pull Walter in was due to △, △ string. However it turned out that Walter also has a "slow" and "fast" pattern. If you get the "fast" pattern, he'll just stop taking knockbacks. Usually a "fast" pattern will result in him teleporting, but occasionally he'll actually attack. Although, first combo has more chances of success.
• After that jump and whip, then use 2 Rubies while Walter does his one and only action. It doesn't matter what attack he uses, it's never enough to kill me, so just tank the hit(s).
• Use 2 more Rubies after that, then do a △, △, ▢, △, △ At this point your combo should be well over 30, make all hits do 250%+ damage.
• After that, jump and do a quick aerial combo to finish him. It's important to note that you don't have time for 4 hits plus Flame Kick, you have to do 3 or less.

Death

Appears after you beat Walter

Patterns

• Minions Death put his hands on his head and say "Minions!" Several flaming skulls will appear and move toward Leon. When they get close, they glow red, and follow that with an explosion shortly thereafter. Death will only use this when he's above 50% HP. This is the best attack opportunity out of all of Death's attacks.
• Scythe Hurl Death twirls his scythe above his head, then throws it in Leon's direction. The scythe will travel across the entire room.
• Energy BoltDeath will gather energy in front of him, then yell "DIE!" The bolts will then fly toward Leon, locking in on him. Death will only use this move if Leon is too far away from him.
• Scythe Slash Death will swing his scythe in a downward arc from Death's right side, hitting Leon if he's too close. Death will sometimes follow this up with another slash from his left side.
• Deadly Tempest Death will raise one hand in the air and shout "Deadly Tempest!" 2 bolts of fire will fall from the sky, sending a shockwave outward from where they land. Death will only use this move when he's below 50% HP.

Subweapons are useless here since Death just reflects them back at Leon. The only useful sub weapon is Hi-Speed Edge, and that's strictly for mobility.

The whole idea here is to keep Black Bishop activated, and just wail on Death with whip combos. △, △, ▢, △, △ is the most effective. Aerial combos should only be used to avoid a Scythe Slash. Flame Kicks can be used when you know there's not enough time to get a full ground combo off before you need to dodge or he moves. Flame Kicks are very hard to keep the combo going on, though, since the window for the combo not dropping is very tight.

When Death uses Minions, it allows for the longest attack opportunities, try to cut a combo short just before he reaches 50% HP. For Deadly Tempest, you can time your double jump for dodging. There is riskier method but the has higher reward. You need to Quick Step once to the left to avoid the first one, the Quick Step 2 to the right through the shockwave. The I-Frames of Quick Step prevent you from taking damage. After that you double jump toward Death, which gets you out of the way of the second one, and puts you over it's shockwave.
