A Work of Mercy in Castlevania Belmont’s Curse is a challenge tied to one Arcana, and each one earns that card a Blessing that changes how its spell behaves. Our maps place six across four Arcana: four in Paris Streets, one in the Palace of Justice, and one in the Library. Three of the Paris four are open by the time The Fallen is down, so begin with the Castlevania Belmont’s Curse Paris Streets map of the Sewer Reservoir.

Map Master’s Alexandru Popescu worked through all six, and the Castlevania Belmont’s Curse wiki and guides keep them next to the Clue trails that unlock each card. Blood Spikes is the one that takes no effort, since its Work completes itself the moment you own two dual-blade weapons.
Every completed Work of Mercy earns one Blessing, which you spend on that Arcana to unlock a Gift, an extra effect for its spell. Rose can equip only one card at a time, so a Blessing on a card you never use adds nothing in a fight. The spells behind every Arcana card help you pick which cards to invest in first.
The full game is reported to have 44 Works of Mercy behind 42 Gifts, since The Cursed has two Works but only one Gift. Unlocking every Gift is what the Pick a card, any card trophy asks for. These six cover about one in seven, spread over Cursed Flame, Holy Cross, Infernal Pyre, and Blood Spikes.
The Cursed Flame Work only asks you to hit enemies with the spell, reportedly 20 times, and nobody has to die. It’s the card Rose starts with, and its Blessing fires a bigger fireball that nudges targets back. If your mana runs dry, melee hits and wall torches refill it, and The Cursed and its starting Arcana covers the card itself.
Both Holy Cross Works open once you have The Fallen’s Holy Cross and Arcane Whip. Ten whip kills is the slow one, since only perfectly timed pulls count, so start early and watch for the brief slowdown that confirms a hit. For five kills with one cross, use the Sewer Reservoir chest with the Cestus, which spawns a wave of monsters around you.
Infernal Pyre’s two Works wait for the Prison Tower roof, where the Joan of Arc fight for Infernal Pyre gives you the card and Holy Light together. The first asks for 15 parries with Holy Light, so tap the parry quickly instead of a long press and pull enemies apart to face them one at a time. Its Blessing refunds 25% of the 80 MP cost for each enemy the central explosion hits after the first.
That refund is 20 MP per extra enemy, so five enemies in one explosion pay back the full cast. The second Work, setting five enemies on fire at once, trains exactly that, and the Castlevania Belmont’s Curse Palace of Justice map of the battle arena leads to the room where enemies bunch up for it. Its Blessing launches anything the spell hits high into the air.
The Blood Spikes Work is the only one you don’t play for. It completes itself once you own two dual-blade weapons, and if you have both the Pair of Longswords and the Rapiers before Carmilla, it finishes the instant you win The Occultist’s Blood Spikes card.
You’ll find the Longswords in a hidden Catacombs room and the Rapiers past the Watch Tower’s closing iron door, both among the dual-blade weapon locations. The Library map of Carmilla’s Observatory points you to the fight, and the Blessing makes a new bleed on a bleeding enemy deal instant damage.
Start with Cursed Flame and the two Holy Cross Works, since both cards are yours early and the Cestus chest gives you a ready-made crowd. Collect the two dual-blade weapons before Carmilla so Blood Spikes completes on the spot, then switch to Infernal Pyre after Joan and save the five-enemy fire for the Palace of Justice arena.
Progress counts only while the right card is equipped, so swap before you start a task rather than mid-fight. Long presses won’t register as parries, and untimed whip pulls won’t count as whip kills, so failed attempts simply don’t add up. The second cross from one Holy Cross Blessing pairs well with the distance damage from the other, so finish both before you judge the card.
