List of Sleeping child locations:

While exploring Streets of Wakes, you can find a Sealed Letter in that area. If you read it from your invetory, you will discover a clue location. You need to follow the clues chronologicaly and after you find all 5 locatios you will unlock A Leap of Faith trophy, and the Seguiriya to the Memory of your Eyes prayer.

Locations:

• Two Moons, the room with the big mirror. Position yourself so you can see your reflection in the mirror and crouch. Just stay crouched for a couple seconds to receive another letter
• City of the Blessed Name. Stand next to the pit where you first dropped into Profundo Lamento. Just stand there for a few seconds and you'll receive another sealed lette
• Mother of Mothers. There's a bell on the ground to the far right room. Hit it a few times and the wall will open to the right, revealing a hidden room. Enter it for another sealed letter you can open.
• City of the Blessed Name and go to the shop on the eastern side. You'll see a skull above the door. Run back and forth a few times across the doorway until you receive the final letter.
• Profundo Lamento. Simply jump off the small balcony room on the left next to the Sea of Ink area, and you'll see a prompt that the curse is lifted

In Mother of Mothers these is a tree stump next to the checkpoint. If you stand there you will hear its voice. Wait until the trophy pops.

• Blasphemous 2 - Mother of Mothers Collectibles

1 of the 3 weapons can be your starting weapon. The other 2 you will need to find. Ruego Al Alba is in Crown of Towers.

• Blasphemous 2 - Crown of Towers Collectibles

1 of the 3 weapons can be your starting weapon. The other 2 you will need to find. Sarmiento & Centella is in Palace of the Embroideries.

• Blasphemous 2 - Sacred Entombments Collectibles

Simply kill 300 enemies with this weapon to unlock the trophy.

There are around 59 enemies in the game. If you explored all areas and collected all items, there is a chance you already have the trophy for finding all enemies. The only thing you need for this one, is to execute at least 50 different enemies. 

The enemies are executed if you press L2 when you stun them before you kill them. Ruego Al Alba has the highest chance for enemy execution. Just keep executing enemies every time you see the prompt, and you should be good. I'm not sure if you need 50 different ones, to me it seemed like 50 in sum is enough, but I could be wrong (I unlocked it naturally).

There are around 59 enemies in the game. If you explored all areas and collected all items, there is a chance you already have the trophy for finding all enemies. Some guides state that you can miss the sand hand enemey in Sacred Entombments, but actually you can reach the bottom of the middle well where Ornate Chalice awaits after the boss fight, and the hand enemy is down there as well.

Most of the enemies you will fight during certain challenges, so it's really hard to actually miss this trophy if you ask me.

There are 4 abilities you can unlock:

• Ivy of Ascension (wall climbing) ability in Profundo Lamento
• Passage of Ash (double jump) is in Beneath her sacred grounds
• Mercy of the Wind (air dash) ability is in Basilicy of Absent Faces
• Scions’ Protection (angel rings, reveals them instead of the golden flies you see in the air) is in The Severed Tower

You will unlock Ivy of Ascension (wall climbing) ability in Profundo Lamento, where the first main story boss is. Passage of Ash (double jump) is in Beneath her sacred grounds, that is below Mother of Mothers area (Afilaor boss awaits down there).

With that that, reach Chapel of the Five Doves (inside Two Moons area) where another 4 boss fights unlocks. First, you will need to go to Basilica of Absent Faces where you can find Mercy of the Wind (air dash) ability. Defeat Benedicta in the Basilica of Absent Faces, and Odon in Sunken Cathedral (through Sea of Ink). Next, go to Labyrinth of Tides, reach The Severed Tower and in that tower you will get Scions’ Protection (angel rings, reveals them instead of the golden flies you see in the air).

Start New Game. Pick up the Alba starting weapon.

From the Ravine of High Stones, reach City of the Blessed Name, then enter Profundo Lamento - pick up Ivy of Ascension, and the Prayer to teleport back to town (pick up the Forgotten Tribute).

Make your way through Aqueducts to reach Sacred Entombments (go left and pick up Veredicto - then teleport back to town).

Go right from the town to enter Grilles and Ruin area. Just go right across the area to reach Palace of Embroideries, where you need to pick up Sarmient & Centella weapon. Teleport back to town.

Back to Profundo Lamento to the checkpoint room that is a few rooms down and to the right. You can now go to the right side by ringing a bell and following this road, which goes down to Mother of Mothers.

If you go right from the bottom of the first area and keep going down until you reach the lowest checkpoint where the big tree is, you can go right and in the next room you need to go down through the vine floor to reach Beneath Her Sacred Grounds.

Reach the bottom and go left to reach the boss and thus unlock the trophy.

You can try this trophy on the first boss fight after the tutorial, which was Radames for me. It comes just after getting Veredicto weapon if you didn't chose it at the start, and it's a perfect opportunity to use it in the fight against Radames. If you met Yerna in Profundo Lamento, she will be here awaiting for you and if you want, she can help in the fight. I encourage you to do so, it will make the fight a bit easier.

The fight starts with phase 1 where you deal most of the damage when Radames runs towards you and hit the wall. You need to jump above, and deal hits to her back. Sometimes Yerma will help, and you can do another attack if she does, otherwise it's advisable to jump away. There are couple of moves to learn, but overal this phase is really easy.

The second phase is a bit trickier, but the idea is the same - jump when the boss is about to rush into the wall, watch out for falling rocks from the air and deal some back hits. Be careful, the boss is quick with the counter, it's better to move away then to risk getting hit. If you work fast you will deplete more HP in the first phase, making the second one easier. It's a bit weird with the phase shifting and knowing when it will happen, so it will take couple of attempts.

You will also unlock Blood and Dust story-related trophy for defeatim Radames.

Unlocking the true power of one weapons means that you unlocked level 2 and level 3 upgrade tree for that weapon and spent Marks of Maryrdom points to unlock ALL of the weapon abilities/upgrades.

Veredicto areas where you can find the upgrades:

• Elevated Temples
• Sunken Cathedral

Unlocking the true power of one weapons means that you unlocked level 2 and level 3 upgrade tree for that weapon and spent Marks of Maryrdom points to unlock ALL of the weapon abilities/upgrades.

Sarmiento & Centella upgrades:

• Choir of Thorns
• Elevated Temples

Unlocking the true power of one weapons means that you unlocked level 2 and level 3 upgrade tree for that weapon and spent Marks of Maryrdom points to unlock ALL of the weapon abilities/upgrades.

Ruego Al Alba upgrades:

• Beneath Her Sacred Grounds
• Crown of Towers

Find all 3 weapons. Ruego Al Alba is in Crown of Towers. Sarmiento & Centella is in Palace of the Embroideries. Veredicto is in Sacred Entombments.

There are a lot of spikes in the game. Simply fall on the spikes and survive (have full HP), and this will unlock the trophy. Almost impossible to miss.

You will use bells to reveal platforms by kicking the bells with Veredicto weapon. Just hit one bell 12 times in a row to unlock the trophy.

There are couple of things to mention in this area. You can find 2 NPCs and solve only one quest for one of these NPCs. Castula wants Scroll of the Elder you picked up in Crown of Towers. Trifon wants Cloth of the Old Woman you picked up in Sacred Entombments.
Depending who you bring the item back, you will either get Rememberance of Castula, or Rememberance of Trifon - the other can be bought from Forlorn Patio shop. When you get Rememberance, you can exchange for altarpiece if you give that memento to sculptor NPC in the town.

For the Two Old Ones Eating Soup trophy place Trifon and Castula altarpieces in one of slots facing each other (exchange Rememberance items at sculptor shop in the city).

16:00 - Two Old Ones Eating Soup trophy

Altarpiece slots can be unlocked in City of the Blessed Name, inside scluptor's shop on the left side of the town. You need to spend Marks of Martyrdom points to unlock more slots. Do so to unlock all slots.

Veredicto is your friend. Fully upgrade this weapon first, and make sure you have the next altarpieces equipped to enhance your fire and Veredicto damage:

• Upper-left slots: The Anointed One, The Traitor
• Upper-right slots: Castula, The Purfified One
• Lower-left: The Thirst, Tirso
• Lower-right: The Unwavering One

Next, make sure you have full mana and health bars, and no flasks (use them all to heal so you have 0 available). Enter some early area with weak enemies, press R1 to imbue your weapon with fire damage, hold the attack button to charge the attack and release - repeat until you do a critical damage and until you unlock the trophy (you can use the nearby checkpoint to retry as much as you want).

Boy, this one requires from you to find all upgrades, all Marks of Martyrdoms, and reveal the whole map. Let's start by listing all collectible categories:

• Altarpieces (check under the main trophy guide, under all Weight of Penance trophy for the list)
• Flask and HP Upgrades
  • Ornate Chalice (you can find 5, 1 in Palace of the Embroideries, 1 in Sacred Entombments , 1 in Sunken Cathedral, 2 in Streets of Wakes)
  • Empty Receptacles (4 to be found, check under Acquired Taste trophy)
  • Silver-Clad Crystal Shard (3 to be found, 1 in City of the Blessed Name, 1 in Palace of the Embroideries, 1 in Elevated Temples)
• Wax Seeds (6 to be found - 1 in Aqueduct of the Costales, 1 in City of the Blessed Name, 1 in Labyrinth of Tides, 1 in Repose of the Silent One, 1 in Two Moons, 1 in Grilles and Ruin)

• Cherubs (Find all 33, and for the list you can refer to the No Cherub Left Behind trophy)
• Forgotten Tribute (3 to be found, 1 in Sea of Ink, 1 in Sacred Entombments, 1 in Labyrinth of Tides). You also need to use them on Procession of the Shadows NPC to travel 3 times, and return back where the carriage was to pick up what they left behind
• Fervent Kiss (5 to be found, 1 in Elevated Temples, 1 in Palace of the Embroideries, 1 in Repose of the Silent One, 1 in Two Moons, 1 in Streets of Wakes)
• Abandoned Rosary Knot (4 to be found - 1 in City of the Blessed Name, 1 in Elevated Temples, 1 in Sacred Entombments, 1 in Profundo Lamento)

Alongside of that, you need ALL Marks of Martydrom upgrade items. I was missing 2 at the end, so let me shorted down where you can find them. I will first list the most common areas where you can miss them (which was the case for me). 

• Use Forgotten Tribute for the first time in Choir of Thorns and return back to that room to get x1
• Use Forgotten Tribute for the second time in Profundo Lamento and return back to that room to get x2
• Use Forgotten Tribute for the third time in Choir of Thorns (different room than the first one) and return back to that room to get x3
• Buy x1 from the moving merchant when he reaches Sunken Cathedral
• Buy x2 from the shop on the east side of City of the Blessed Name
• Find x1 above the lowest checkpoint that is next of the boss fight in Beneath Her Sacred Grounds. You need double jump and this is the most missable one to be found - this was my last one
• Find x10 in Garden of High Choir by climbing the tower after you get all 33 Cherubs
• Find x5 for giving all Sculptor Tools to the Sculptor in the town
• x3 of them are in Mother of Mothers (2 of them are in the upper-left corner rooms, I've missed 1 here as well.
• x25 of them are rewards for killing all game bosses
• x40 can be farmed by simply killing enemies. 40 is the limit, the rest you will need to find

The rest are divided by collecting item pickups and yellow altars across regions. It's mostly easy to find them all, especially if you left the marks on your map as you progressed - I didn't, so I had to go through all areas to find what I was missing. There is a great video on the YT where all of the Marks are shown, maybe that can also help you.
