Crimson Shroud contains examples of the following:
Ancient Artifact: The "gifts", which grant magical power to their wielder. The Church claim that the original gifts were divine relics created by God, and produce copies to distribute throughout the world. However, the "Defence of Heresy" manuscript claims that the original gifts were temptations created by the Devil to entrap human souls.
Book Burning: Giauque, upon coming across a ransacked library with incredibly old books, wonders whether or not the goblins are destroying such precious knowledge deliberately.
A few bloodied and torn pages lie in the corner—paper used for a sword rag. To the goblins, that's all these books are: paper, without any value beyond their physical use.
Or maybe they do know their value, and they burn them anyway. The thought chills you more than any of the horrors you have seen in this place.
Character Level: Averted. All of your characters retain the same base stats throughout the entire game, which can only be enhanced by gathering better loot.
The Chessmaster: The Big Bad spread the rumor of the "Original Gift" to lure curious adventurers to her prison, hoping one such adventurer would be a Qish so that she can possess them and begin the Apocalypse.
Creator Thumbprint: It's not an Ivalice game but it certainly feels like one due to Yasumi Matsuno's style.
Deal with the Devil: The Big Bad made one such deal so that she could take revenge on those who had betrayed her. The Chosen of the Solis made subsequent deals to fill the Sun-Gilt Palace with monsters that would stop anyone from freeing the Big Bad.
Demonic Possession: What Abagail intends to do in order to free herself from the shackles of the Sun-Gilt Palace.
Downer Ending: The Frea with whom Flint has been speaking is actually Abigail, the Big Bad of the game, who is spinning a tale designed to lure Flint and his men into a trap. He falls for it and is trapped within the Sun-Gilt Palace along with Giauque and Lippi, leaving Abigail free to wreak havoc upon the world.
Dungeon Crawling: The plot of the game is Giauque, Lippi, and Frea scouring the Sun-Gilt Palace of the Rahab in search of the Defense of Heresy and the Crimson Shroud.
Early Game Hell: The first half of the game: you're learning the eccentricities of the battle system, the healing spells you have aren't quite good enough to match the damage you'll be receiving, and Chapter 2 confronts you with the infamous "grind a bunch of mobs until you get a rare drop" bit. It gets easier once you find the Healing Staff, which grants the Heal II spell and boosts your survivability tremendously.
Ethnic Magician: Frea (and by extension, the Qish). This is because they are direct bloodline descendants of the ones who received the original gifts via Deal with the Devil.
Fantastic Racism: The Qish, an ethnic group without a homeland who are persecuted for their "heretical" teachings. Then you find out the reason they don't have a homeland: they brought gifts into the world via Deal with the Devil and the resulting power struggle plunged the world into chaos.
Felony Misdemeanor: The Chosen of the Solis poured lead into the eyes of one of their own and cut off her fingers and toes because she loved the king while he had a wife. She was perfectly content with burying her feelings, but this would push her across the Despair Event Horizon.
First-Person Smartass: Giauque displays some of this, usually toward Frea. He generally knows better than to snark the hell out of Freaaloud.
Foreshadowing: When speaking to Flint, Frea has a habit of wetting her lips. It's a tic she never displays when with Giauque and Lippi, hinting that the "Frea" talking to Flint is a different person.
Genre Throwback: Of Tabletop RPGs, complete with the character models having metal bases as if they were gaming miniatures.
Guide Dang It: Good luck figuring out where to find the key in Rahab without looking it up. note It's hidden in a magically-darkened room. To light up the room, you need an item called "Obsidian Daphne", an otherwise unremarkable rock whose power to make braziers burn brighter is only alluded to in its flavour text. The item itself is an rare drop from Skeleton Mages, who in turn are a rare spawn (1 in 4). And you still need enough Barter Points (200) to actually claim it after the battle. Finding out how to access all of the new areas that can be found in New Game+ can be frustrating as well, with more than one key being a rare item drop.
The Healer: If you want to stay alive in later battles, especially in New Game+, Frea is going to be taking on this role almost exclusively in most encounters.
Jerk Ass: Flint, who — depending on player choice — will either (against the medic's protests) give the badly-injured Frea hilua powder, which is poison when someone's body is weakened, or else attempt to forcefully wake her up by brutally grabbing her by the nape of her neck, yelling in her face for her to awaken or he'll strangle her, and shaking her despite her life-threatening injuries. And then he has the poison poured down her throat anyway. The extreme reaction may come as something of a shock to the player, as the choices are either 'Demand again that Frea be wakened' or 'Shake Frea awake'. Many chose the second, expecting a gentle shaking of the shoulder rather than just about ripping the poor girl's head off.
Jerk with a Heart of Gold: Despite all of this, and despite considering Giauque his enemy, once Flint learns the truth, he doesn't hesitate to gather a team and personally go into the palace after them in an attempt to either save them, retrieve their bodies, or cut down their reanimated bodies to give them peace in death. And this despite his previous three teams ending up dead.
Luck Manipulation Mechanic: Rolling dice to alter the accuracy of a move, which can be surprisingly complicated. note Since the dice roll has to produce a binary hit or miss result, the accuracy percentage is rounded up to the next fraction the dice can actually roll. A d4 can only roll in increments of 25%: so if you use 1d4 to augment a move with 55% base accuracy, the "to hit" number is set at 2, giving the move a practical accuracy of 75%.
New Game+: All learned skills and all items (except key items) are kept, enemies get stronger, and new areas can be accessed (complete with new chests and bosses). Why are there so many changes? Because the person telling the story is different, leading to the Golden Ending.
Nintendo Hard: The game is incredibly punishing, but all of the relevant information is there. Much like Vagrant Story, success comes from learning the mechanics of the game and adjusting your equipment/moveset to account for the enemy types. A weapon that offers a specific advantage against the enemy type you are facing tends to be far more effective than one that simply boosts your Attack stat.
Sealed Evil in a Can: Abagail, the person who made the originalDeal with the Devil that led to the creation of the gifts. As she had been granted immortality from the pact, she was sealed away within the Sun-Gilt Palace instead.
Stylistic Suck: The characters are rendered as nothing but playing pieces with little stands underneath them. Probably saved a lot of money on needing to animate the characters—there is no animation for the cutscenes.
Unreliable Narrator: The revelation that the "Frea" Flint has been talking to is actually Big Bad Abagail sheds doubt on how much of her story was true and how much was a lie designed to lure Flint into her trap. The fact that the real Frea tells a different story in a New Game+ (featuring harder enemies and new areas) hints that this is a more accurate version of events.
Visual Novel: Shades of it. There's no animation in the characters during cutscenes (they are, of course, just little figurines that can't move) so everything is described through verbose, Woolsey-esque narration.
