Requirements & Scaling

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

"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

  • Requires Blood Stone Shards and Blood Echoes to fully upgrade.
  • This is one of two skill-based weapons in Bloodborne that has direct scaling with arcane for damage output.



  • Can be purchased from the Messengers for 40000 echoes after obtaining the Crow Hunter Badge from Eileen the Crow's quest line.
  • Killing Eileen is also a way to get the weapon early in the game.
  • While progressing through Eileen's quest, it's possible for her to be killed by Henryk and thus drop the Crow Hunter Badge as a result, although the quest line will end.

Player Notes


  • The normal form of this weapon is a curved sword with a standard and versatile move set. Very standard.
    • 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 mean time.
  • 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 favouring 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 backwards 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 backwards 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[1]
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.
    • Siderite 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.


  1. ^ Please note that the developers used the concept of magnetization (probably the siderite allusion) liberally, making some of the moves of this weapon hard to describe. Please see the moveset video if the following descriptions are confusion

    • 05 Mar 2017 06:40  

      the minimum stamina to use them effectively i think is 141, this allows for 2 R2 attacks followed by an L2 and a backstep, giving thus a very strong combo and also gaining a fair distance from the enemy, if you level up skill and arcane enough, they get pretty good and can one-combo kill almost anythin, the only problem is the low stagger potential.

      • 03 Jan 2017 08:46  

        In the chalice dungeon sz73v83s the weapon is in the layer 2 before the boss. It also has the Ring of Betrothal in the same layer: Go down in the elevator and then to the right.

        • What if the Eileen bug happened?05 Jul 2016 08:51  

          Eileen didn´t appear in my game. At no stage. Any other way I can get the blades of mercy? Kinda want to have it before I start NG+ and I´m right before the true last boss.

          • Is the normal method confirmed?05 Jul 2016 08:51  

            This weapon didn't become available to me until after I had beaten the Blood Starved Beast. Had the badge from Eileen from when she died; well before that. The crow set however was available from when I first got the badge.

            • build focused mainly on BoM and arc05 Jul 2016 08:51  

              I have been thinking about making a arcane build with focus around burial blade and maybe holy blade(with fire gem maybe?) instead of burial blade. So i was wondering what would be the best stat set up. would it be with str/skl/arc being 25/25/25, 16/25/40-50, or ignore str and stack skill/arc to 40/40 my main goal is to stay at lvl 100 until the community decides to stick with this or raise it a little more. Kinda wish I knew how to work the build calculator to find out myself since i'm no real math expert and i'm not entirely how this new system works.

              • Note the attack speed05 Jul 2016 08:51  

                One interesting thing about this weapon is that the more you combo with the dual-wielded attacks, the faster they become. Throw in a decent amount of endurance and you'd be able to one-round stunlock most enemies in depth 4+ dungeons, even with a 30/20 build.

                • Should I start over?05 Jul 2016 08:51  

                  Soooo I finished Eileen's quest and realized this weapon is awesome, but it scales with skill AND arcane. Im level 64 with stats at 29/25/18/25/12/8 or something along those lines. I have heard there is no respec in this game, so I wanted to know if it was viable to keep this character and just dump what I can into arcane and skill from here on out, or if I would be better off just starting over again. What has the community decided the unofficial level should be, and are certain points expected to be at a certain level? I seem to recall 30/30 in health and stamina in DS2 was fairly standard.

                  • PVP- No REAL skill required05 Jul 2016 08:51  

                    In pvp this thing is ridiculous. The quickstep R1 is overpowered, takes no skill and simply needs a nerf. The rest of the moveset is bad in pvp, easy to viceral atk. I think quickstep R1 needs debuff and rest of the movesett a buff. What do you guys think?

                    • a massive burst wpn05 Jul 2016 08:51  

                      I've been working a build with these blades using 30 end, 50 skill and 25 arcane. It is an absolute power house of burst dmg. Because of its trait of speeding up as you swing and high stamina its A whirlwind of dmg. Idk if anyone has tested it but I've seen the blades have a dmg stack like the rosmarinus after so many swings that land.

                      • uncanny version05 Jul 2016 08:51  

                        i found in the first hallway of the second layer.....the first boss are the beast possesed soul....very easy <br/> <br/>sinister loran with sin.bell.....bavxjjzt

                        • poison and fire05 Jul 2016 08:51  

                          got invaded by some dude and my blade had fire ele equiped with rapid poison the fire damage during the fight was easy to spot but could never see his health drop from what should b poison procs (i unleashed alot of half combos with dual on him) anyone know for certain if fire n poison cancel each other out?

                          • Warning05 Jul 2016 08:51  

                            Whoever keeps adding to this that the blades only do the arcane damage on certain hits is an idiot and doesn't understand how split damage weapons work.

                            • IMO the best "roll attack" in the game.05 Jul 2016 08:51  

                              The little double stab you do with these things in dual wield mode has almost absurd range for little daggers, and they do crazy good damage per hit too and combo easily into R2 or L2 if you like. I'd even go as far as saying they're the biggest reasons this weapon's so good.

                              • Best build for the "siderite" weapons?05 Jul 2016 08:51  

                                So I'm about to start a new character and I want to build it just for this and burial blade but I'm terrible with this scaling thing (this is my first souls game) so I want to ask y'all: what is the best build for those two weapons? I'm thinking about staying anywhere between 120 &130.

                                • Something to put in the Player's Notes...05 Jul 2016 08:51  

                                  "The weapon's attack speed also works against it, as you'll degrade the weapon very quickly in comparison to other weapons."

                                  • after 50?05 Jul 2016 08:51  

                                    I have skill and arcane at both 50, strenght at 16. <br/>Am I better off levelling up strenght to 50 or maximising the skill and arcane to 99 to get the most out off the weapon?
