Demon of Obsession is one of the tough mid-to-late game bosses in Wuchang: Fallen Feathers you will fight in the Shrine Dwelling at the Bo Capital. She’s a fast, aggressive opponent with a dangerous mix of melee combos and heavy-hitting magic, and once her health drops below half, she begins to teleport and unleashes her most lethal attacks. This guide covers how to find Wuchang Fallen Feathers Demon of Obsession boss, explains her phases, how to survive her spell onslaught, and uses proven tactics to defeat her and claim the rewards.
Where to Find the Demon of Obsession in Wuchang Fallen Feathers
In the late-game Bo Capital region, you’ll come across the Depths of the Capital shrine. Facing this shrine, look to the left where you will see a red riddle gate, a secretive doorway. To activate it, you need to answer the riddle incorrectly: choose “The wheel turns anew.” That response opens the path to the hidden Shrine Dwelling area, where you fight the Demon of Obsession.
However, you’ll need to meet specific prerequisites to make the gate appear and access it. You must have already completed the questlines of Fang Yao and He Youzai, and then backtracked to defeat Eternal Glory (Zhao Yun) in Avian Dwelling. The red gate only appears when these conditions are met. After passing through the gate, you will be up against the Demon of Obsession in a sealed-off battleground.
Make sure to stock up on healing gourds, have your armor optimized for magic resistance, and slot any talismans that help against ranged spell damage. Demon of Obsession punishes with high burst magic, so preparation is half the battle.
Demon of Obsession Combat Style and Attacks
Demon of Obsession is reskinned as Inner Demon and the “ultimate duelist” in Wuchang: Fallen Feathers. She mixes weapon mastery with heavy magic and comfortably transfers between aggressive melee pressure and ranged spell harassment without skipping a beat.
Unlike most bosses, her moveset is like fighting two enemies in one body. In the first phase, she uses a spear to control space, punish your whiffs, and keep you at mid-range. In Phase 2, she switches to a one-handed sword, becomes faster and more unpredictable with teleporting around the arena, and combos all her deadly spells.
A big challenge here is her mix of counterable and non-counterable attacks. She’ll frequently slip unarmed strikes into her combos, which cannot be parried, thus force you to continuously read her tells instead of performing reflex counters. On top of that, her Ethereal Form teleport is used aggressively; she’ll blink out of your reach or suddenly reappear behind you to keep giving pressure.
To make matters worse, she inflicts multiple status effects depending on her spell choice including Burn, Frostbite, and Paralysis, so you can’t stack resistance to one element and call it a day. Failing to manage debuff buildup will quickly put you on the back foot. To survive this battle, read her weapon stance, track her teleports, and never over-commit. She’ll punish impatience with brutal combo strings that can chew through your health bar in seconds.
Demon of Obsession Boss Fight – Phase 1 (Spear Mastery)
She starts the fight with the spear in hand and will stick with it until you reduce her to half HP. The spear’s reach allows her to tag you from outside your melee range, so your timing on dodges or parries is crucial.
Her common spear combos include:
- Rush-Thrust Opener – A spin into a forward charge, finishing with a heavy thrust. If you block too early, the thrust will catch you. The safe response is to late sidestep.
- Spin-Jab into Mix-Up – A forward jab followed by either a spinning slash or a jumping slash, and then a slow, flourish-heavy downward strike. The delay on the final hit is a trap for overeager punish attempts.
- Triple Spin Slash – Three consecutive wide spins that will shred your guard if you try to block them all. Roll toward her after the first spin to get inside her arc.
- Triple Forward Jabs – The third jab has a noticeable pause before it lands. Many players panic here and roll too early, wait for the actual lunge before evading.
She’ll also deliver jumping stab attacks from range, usually chained directly into a spell cast. When she does this, you should expect immediate AoE danger zones or projectile follow-ups.
Demon of Obsession Boss Fight – Phase 2 (Sword & Magic Aggression)
At half health, she ditches the spear for a one-handed sword, and the fight shifts into a much more aggressive pace. The sword phase is harder to counter due to her blistering mix of weapon and unarmed strikes.
The main sword combos to watch for are:
- Six-Hit Blitz – She strikes with two punches, three rapid kicks, and then a spinning downward slash. The opening hits are uncounterable, so focus entirely on dodging until the sword swing lands.
- Jump-Spin to Overhead Slam – Jumping spin slash into a forward jab, then a massive overhead strike. The slam has huge knockback potential, so don’t get cornered.
- Magic-Charged Dual Sweeps – She infuses her sword and performs two lunging, sweeping attacks with far more reach than her normal swings. Roll toward her, not away, to avoid getting clipped by the second arc.
- Four-Hit Magic Combo – Begins with two diagonal upward slashes, then an overhead slam, and finishes with a horizontal slash projectile. If you block the projectile, watch for her to close the gap instantly with a teleport.
- Quad Slash Projectiles – A ranged harassment tool where she slashes four times in quick succession, sending blue glowing magic waves toward you. Roll diagonally forward to dodge while closing the distance.
She’ll also mix in her blink-punch and blink-kick strings, which can chain up to six hits. You can’t counter them directly, so movement is your only defense.
Magic Threats in Both Phases
Throughout the fight, she’ll rotate through dangerous magic attacks without warning:
- Echo of the Bo Magus – AoE tentacle slam, big damage if you’re caught inside.
- Thunderstorm & Heavenly Thunder – Lightning-based area denial; watch for Paralysis buildup.
- Echo of Ai Nenqi – Fires explosive thunder arrows that punish you for turtling.
- Echo of Dhutanga – Sends a wave of fire across the arena, adding Burn buildup.
- Echo of the Great Centipede – Sweep laser beams from above, keep moving.
- Echo of Liu Cheng’en – Snow whirlwind that builds Frostbite incredibly fast; disengage immediately.
How to Defeat the Demon of Obsession – Fight Strategy
Demon of Obsession has the things up her sleeves to punish nearly every mistake, so this is not a battle you win through brute force, but one that asks you to play the long game and react correctly to each phase to claim victory. You have to break her rhythm and force her into recovery states. Her spear has punishing reach, but most of her strings have small pauses between the last hit and her next move. Watch for:
- The jab-spinning mix-ups — the final heavy thrust is slow; dodge late and punish.
- Wide sweeps — rolling inward after the first swing puts you in prime backstab position.
- Jumping thrusts — often chain into spells; get ready to dodge twice in a row.
The initial phase requires patience. Don’t chase her after a teleport as she often uses the blink as bait for an instant counterattack. Track her position, let her commit to a charge, then punish her whiff.
Once she switches to the sword in the last half stage, you have less breathing room. Thankfully, the sword’s range is short, so you can bait her into whiffing far more easily but she’ll chain unarmed strikes that can’t be countered.
- When she opens with punches/kicks, resist the urge to parry, dodge until you see a sword slash.
- If she casts spells mid-combo, reposition yourself; she leaves herself open for half a second as the animation transitions.
- Her projectile strings (quad slash waves) are a great time to close distance — roll diagonally forward through them and punish.
In both phases, the biggest trap is overextending after punish. She recovers faster than most bosses in Wuchang, and she can immediately cancel recovery into a blink strike. Always hit once or twice, then back off.
Recommended Build & Preparation
Weapon Choice:
- A fast weapon with good recovery (dual sabers, one-handed sword, or spear) is ideal. Heavy weapons can work if you’re disciplined, but her speed punishes slow recovery frames.
- Inflict Bleed or Burn to apply passive pressure — she’s not immune to either, and small ticks of damage add up over the fight.
Talismans & Accessories:
- Equip accessories that boost stamina regen because this fight is a dodge-heavy marathon.
- Carry status resistance charms for Frostbite and Paralysis, she rotates elements constantly.
Consumables:
- Bring multiple Antidote-type items for status recovery.
- If available, equip damage reduction buffs as many of her combos can otherwise two-shot you on New Game+.
Armor:
- Light-to-medium armor is a good choice, you need i-frame windows more than raw defense.
