Blade of Mercy is a Trick Weapon in Bloodborne; it's one of two skill/arcane hybrid weapons.


Blade of Mercy Description

"A special trick weapon passed down among hunters of hunters. One of the oldest weapons of the workshop.
Splits into two when activated. The weapon's warped blades are forged with siderite, a rare mineral of the heavens. Most effective swift attacks,such as after a quick-stepping."


Blade of Mercy Information

  • Transforms from a single-handed short-sword to dual-blades wielded in both hands.
  • Deals bonus damage when performing quick-step, sprinting, backstep, and transformed L2 attacks.




  • Can be purchased from the Messengers for 40000 echoes after obtaining the Crow Hunter Badge from Eileen the Crow's questline.
  • Eileen will drop the Crow Hunter Badge when killed.
    • It's possible for Eileen to be killed by Henryk and drop the Crow Hunter Badge as a result.

Player Notes

  • The normal form of this weapon is a short sword with a straight-forward but versatile move set.
    • Despite what its small size may imply, it deals decent damage per attack in addition to having fast swings.
    • As such, it has a higher than average DPS but suffers extremely short range in the meantime.
  • On the flip side, the transformed mode utilizes dual mini-curved swords that have a faster attack speed; this comes at the cost of disabling a normal left-handed weapon and less damage per individual strike.
  • R1 attacks in the transformed form slowly speed up as you continue attacking, capping after the fifth strike.
    • In PVP, if you believe you can win a battle of attrition, it can be used to bait an opponent into overextending a skirmish, especially if the opponent is unaware of the wind-up attack speed.
    • Be careful not to spam this tactic; smart opponents will unleash visceral attacks if they realize what you're trying to accomplish.
    • Appropriately enough, this is good for fighting most NPC hunters, though. If you can get in close and get their back to a wall, you can stab them until your stamina runs out since they'll flinch with about every hit and be unable to retaliate. Just remember to leave them no space to backstep away; they'll be able to do it that way. Practice it a bit, then get in there and get an early start on the sky burial the next time you're fighting an NPC hunter.
  • The Blade of Mercy is best suited for fighting individual targets rather than a group due to its move set; this is due to the weapon's kit favoring sidestep thrusts and quicksteps that are difficult to retaliate against in a battle of speed when your opponent is alone.
  • Rally is somewhat low due to the weapon's fast attack speed. Combos with this weapon can potentially alleviate this issue, but take care not to exhaust your stamina in the process. Disengage at low stamina with a backward dodge or an L2.
  • This weapon lacks the ability to do a charged R2 attack in transformed mode but has a 2 R2 combo.
  • Due to its fast attack speed, it can be useful for inflicting Rapid or Slow Poison.
  • L2 attacks in the transformed mode causes the hunter to attack and hop backward simultaneously.
    • This is useful as a defensive mechanism since it grants you breathing room from your opponent.
    • It's also useful as a finisher to any combos you unleash on an opponent, dealing considerably high damage and distancing yourself so that you can recover stamina.
    • Make sure you are directly in their face for this, as it has one of the lowest ranges in the game.
  • Think like a rogue/assassin/thief from a traditional RPG when using this weapon. You will typically not win battles by brute force, but rather through speed, patience, positioning and dedication.
  • The blade lacks decent heavy attacks to stun heavier foes but the transformation attacks can be used as heavy attacks.
  • This weapon has many similarities to the Burial Blade.
    • Both weapons have a direct scaling with arcane towards their damage outputs.
    • They cannot be buffed by external sources.
    • Furthermore, it's impossible to modify their damage type into Fire/Bolt/Arcane through blood gem fortification.

Move sets & Videos

Moveset testing done by - Castielle Castielle.

Regular Move set
Numbers were tested on a level 120 player with no armor using a +10 Blade of Mercy.
Move Damage Type & Modifier Stamina Effect
R1 Combo physical_atk.jpgarcane_atk.jpg1.00x, 1.02x, 1.04x 15 There are three moves in the combo consisting of horizontal slashes. The first is right to left followed by left to right with the third being right to left with a slight upward motion as well. The even attacks (2, 4, 6) are all the left to right slash. All right to left slashes (odd numbers) except the first use the motion that includes the slight upward trajectory. This has very little stamina cost and can create very long combos. In addition, since all of the attacks are basically the same, pacing and consistency make this an easy combo to utilize.
Quickstep R1 physical_atk.jpgarcane_atk.jpg1.50x 25 There are three quickstep animations. Stepping right or back creates a quick forward hop and slash from right to left. The left step is reversed with the slash animation. Stepping forward leads the character to drag the blade from the ground to the side of the left foot and up on a diagonal, ending at about shoulder height. The front step is the only one that doesn't have a hop forward, instead taking only a short step.
Backstep R1 physical_atk.jpgarcane_atk.jpg1.50x 25 The backstep R1 has a quick forward lunge which includes a horizontal slash from left to right.
Rolling R1 physical_atk.jpgarcane_atk.jpg1.50x 25 The blade is quickly slashed from the ground near the left foot, up and to the right ending at just above shoulder height.
Dash R1 thrust.jpgarcane_atk.jpg 1.40x 15? (+run) The hunter ends the run with a step and forward stabbing motion.
R2 Attack physical_atk.jpgarcane_atk.jpg1.25x 30 The hunter reverses his grip on the blade and brings it behind his body, then quickly slashes forward right to left and returning the grasp to the standard position.
Charged physical_atk.jpgarcane_atk.jpg2.00x 50 The charge starts off with the same grip change as the R2, but drags the weapon a little further behind the body. Instead of slashing from right to left horizontally, the blade is brought up in an uppercut motion ending above the head.
Backstep R2 thrust.jpgarcane_atk.jpg1.80x 35 Following the backstep, the right foot takes a quick step forward followed by a longer step with the left. The blade is then brought forward with a stabbing motion out and up (as if aiming for a human opponent's neck) and is twisted as it moves forward
Dash R2 physical_atk.jpgarcane_atk.jpg1.80x 30 (+run) As the hunter runs, the blade is brought in front of the stomach while the body begins to rotate (right foot drifts behind the character). The hunter uses the momentum to lean forward while finishing the rotation of the body and slashing from left to right horizontally. Despite the short nature of the weapon, this move has a larger arc of attack and can be used to wade into a group of enemies and hit multiple foes.
Leap physical_atk.jpgarcane_atk.jpg1.50x 35 The leap is fairly consistent with other weapons, with a jump forward and a downward diagonal slash from right to left.
Transform Attack physical_atk.jpgarcane_atk.jpg1.20x 15 (+15) The first (backstep into transformation) has the hunter bring the weapon to the right hand side. As it's brought forward in what looks like a normal horizontal slash, the two daggers come apart. The blades appear to be magnetized and hold together at the tip, with the second blade whipping around the tip of the first in a circle. Meanwhile, the left hand has stored its weapon and catches the handle of the second weapon to go into the two hand stance.
The second animation (following an attack) is similar to the first, except the blade starts at the left side of the body. The weapon is cast out and again the left hand dagger separates and whips out from the right hand dagger (connected by the tips) and comes back to the left hand.
Fun fact: the standard transformation (not attacking) has the left hand stowing its weapon and simply grabbing the handle of the second dagger. Both hands raise up and separate the blades. A shower of sparks are created from the two tips unlocking which suggests this is where they're primarily joined.
Transformed Move set
Numbers are rounded to the nearest 100th.
Move Damage Type & Modifier Stamina Effect
R1 Combo physical_atk.jpgarcane_atk.jpg0.90x, 0.90x, 0.90x, 1.25x, 1.10x, 1.12x, 1.18x, 1.18x 12~ for first 3, then 15 each hit after A basic combo involving a flurry of attacks with both hands wielding the transformed blades. They are: Right hand downward diagonal right to left, left hand left to right horizontal, right hand uppercut slash, both hands from overhead slashing down and then out, right hand forward stab, left hand (with reverse grip, blade held down) slashing to the right and up, right hand mirroring the last move (reverse grip slash to left and up), left hand forward stab. At this point moves start to repeat (right hand stab, then left hand reverse grip slash). At the fifth attack (right hand stab), the combo speeds up dramatically. All attacks are mostly in front of the player making this best used for one on one combat.
Quickstep R1 physical_atk.jpgarcane_atk.jpg1.40x 30 All four quickstep animations are a rapid lunge forward with the hunter bringing both blades to the front in a thrusting motion.
Backstep R1 physical_atk.jpgarcane_atk.jpg1.40x 25 The hunter hops forward with the right hand knife near the stomach. It is drawn forward in a left to right slash.
Rolling R1 thrust.jpgarcane_atk.jpg 1.40x 25 The hunter quickly stabs both blades directly in front at about abdominal level.
Dash R1 thrust.jpgarcane_atk.jpg1.40x 25 (+run) The hunter lunges onto the right foot and stabs forward at about stomach height.
R2 Attack physical_atk.jpgarcane_atk.jpg1.50x, 1.60x 45 (follow up is 50) The R2 attack is actually a short (two hit) combo. The first has the hunter bring both blades to the side at about shoulder height and slash them both front and across (right blade ends on left side and left on right). The follow up attack has a quick hop forward and both blades are brought back out again (out and up symmetrically). The second attack slashes at about leg height.
Charged None none  
Backstep R2 physical_atk.jpgarcane_atk.jpg1.70x 35 Both blades are brought to the low and into the body (across the stomach). The blades are both slashed outward, with the right hand moving out and up and the left hand moving out and down.
Dash R2 physical_atk.jpgarcane_atk.jpg1.70x 30 (+run) This is similar to the dash R2 of the other mode. The right hand is brought into the stomach as before while the hunter rotates in the same direction (right foot drifting behind). However, instead of simply leaning into the attack, the character does a short leap forward and slashes with both blades as the left catches up with the spin.
Leap thrust.jpgarcane_atk.jpg1.50x 45 The hunter leaps forward, reverses the grip of both daggers and stabs them into the ground.
L2 physical_atk.jpgarcane_atk.jpg1.50x 45 The hunter raises both blades overhead and brings them down and out to the sides creating an "x." The character also hops backward. This move is well suited as a final strike following an R1 combo as it will set you away from your enemy after slicing.
Transform Attack physical_atk.jpgarcane_atk.jpg1.30x 15 (+15) There are two animations that are functionally identical for this move. In every instance, the grip is reversed on both blades. They are brought overhead and rejoined and brought downward and to the side in a stabbing motion that ends at the hunter's side. Attacking prior to the transformation leads to a slash toward the right side of the body. An evasive action (quickstep, backstep, roll) will result in the stab heading to the left.


  • The Blade of Mercy was originally named as "Warped Twinblades" during the Alpha test, and it was the tool of choice for the "agile" hunter.
  • Both the Burial Blade and Blade of Mercy make mentions of a mineral known as siderite in their descriptions.
    • is the real-life alternate name for an iron meteorite, and it seems to be the reason why arcane power has direct scaling with both blade's damage output. Due to its extraterrestrial origins, that may explain why it cannot be buffed by an external source of any sort.
  • It loosely resembles the Eleum Loyce from Dark Souls 2, a sword with two blades at the front.

      I swear sometimes that quickstep stab travels two inches and other times it's Noctis's warp strike. Not that I mind. It's endlessly entertaining.

        IMO this paired with the burial blade is the best 2 weapon setup you can get. The fastest single target murderer, alongside the best wide reaching crowd sweeper.

          Light speed kitchen knives. Not a poise breaker in the slightest. These things are not the easiest to use but paired with a longer weapon such as the rakuyo or burial blade this thing is amazing. Full beast is best btw cus it makes these things hit like sanic after some orange juice.

            This thing is good for close range and quickstepping.
            I am good at neither. Most people that first try this game are not good at close range.

                        If you play the game like I do, and tend to hover just outside your opponent’s effective range and never missing an opportunity to strike, these will serve you well. If you play like most people and want raw damage per hit and braindead ease of use, look elsewhere.

                            Does anyone know if levelling up the Arcane attribute increases the bonus arcane damage or just the physical damage?

                              Because so many people are dumb and think that Blades of Mercy are bad and that arcane scaling is worthless on them etc etc. I’d like to point out exactly why you take Arcane with these. You’ll be in transformed mode 99% of the time; they’re extremely close range... so, you get value out of the “spells” to compensate for your lack of range. NG+ you get to add in the burial blade to your setup. You also get to remain highly mobile, which is incredible. You’ll weave through enemies like a mad dancer, and then cast spells randomly. The kits wildly unpredictable and has probably the highest skill gap of any weapon in the game. Which makes it the best weapon in the game.
