Made a Slave: Though it's less a slave, more a sacrificial offering.
Stable Time Loop: Caught in a nasty one. Namely, he's the Sorcerer who will become Magusar. He will sacrifice Magusar, and resurrect the world. Unfortunately, the corruption of Magusar will then affect him, and he will take on the identity of Magusar. Which leads to the events that occur in the game.
The Player (Soul Sacrifice Delta)
Meaningful Name: Doubly so. Ceryx Camlann. Ceryx was a Greek Demigod, the son of Hermes who served as a messenger of the gods. Camlann was one of the most important battles in the King Arthur Mythos. Perhaps more importantly, very fact that he has a name shows that he is not the Nameless Sorcerer, suggesting that the world is finally starting to break free of the Eternal Recurrence.
Limit Break: The Sorcerer can unleash the Black Rites when he's low on health.
Nuke 'emwith Fire: Infernus hits everyone on the map, at your skin's expense, halving your defense.
Chain Pain: The Gleipnir rite summons a bony chain by ripping off the right arm, useful to restrain an Archfiend. However the sigils you carved in your right arm will stop being effective.
The Blacksmith: The Vulcan rite, outside of healing everyone within range and sending shockwaves, allow your allies to gain swords made out of your soul. The lack of an heart will reduce your health by half.
Big Fucking Sword: The Excalibur rite summons a giant sword that hits one enemy For Massive Damage. Like Vulcan, it requires your heart. Unlike Vulcan, however, the side effect is a gradual loss of health. What else did you expect taking that kind of sword from your mouth?
Storm of Blades: If you're willing to sacrifice your partner, the Gungnir rite will rain down bony spine-like spears from the sky. Sure, your partner won't be actively fighting anymore, but he will have better rewards and will be able to see someone's exact health bar.
Blow You Away: The Berserker rite, at the price of the brain (thus rendering you unable to distinguish your offerings), can lure everyone towards you and blow them away.
Light 'em Up: The Angelus rite uses your bones to summon wings. Said wings pierce through enemies and heal allies. However, you lose your ability to evade and your movement is reduced.
Weapon of Choice: Outside of the swords and the axes from the aptly-named weapon offerings, the available offerings include, but not limited to, projectiles, fists, shields, armors, blood sprays...
Fur Bikini: The female variant of the Hunter raiment.
Stripperific: The female variants of the raiments, some more than others.
Reader Avatar: The means by which the player experiences the memories contained within Librom.
Sanity Slippage: He begins growing increasigly bloodthirsty after sacrificing Sortiara. Sacrificing Illecebra cures him of this.
And I Must Scream: Even when Magusar is completely taken over by the soul of the mad wizard whom he defeated, the Boss Banter during the final battle shows that he is aware of what is going on and wishes to be killed.
A strange sentient tome that appears to be made of flesh, with eyes and a mouth on the front "cover". Within him is the secrets of what happened in the past and the means to defeat Magusar. The tale contained within Librom's pages were actually a depiction his own life. His real name was Geoffery Librom, and he was a sorcerer of Avalon who partnered with Magusar.
Jerk with a Heart of Gold: He's very rude and abrasive to the player, but is still doing everything in his power to save them. He becomes nicer as the story goes on.
Passing the Torch: The protagonist absorbs all of Librom's memories and powers before fighting Magusar. This is taken even further in the savior ending where the protagonist literally becomes another Librom.
Mutated spiders that seek constant food supplies, growing false fruits on their bodies to lure prey in.
Bees that have mutated due to magic, who overthrew the queen bee.
Rabbits transformed by magic, their ears growing into hand-like limbs.
Snails transformed by magic, their shells turning into treasure chests.
The only child of a renowned knight who only sought her father's approval. She became a knight, hoping to gain her father's love by becoming the son he never had. Despite her skill, the disparity of strength between her and her male opponents made her fall into despair. She sacrificed her beauty to the Chalice to double and redouble her skill, becoming a literal dynamo in the process. After hearing that her father died on the battlefield, she sought to become the greatest knight in the world, that her glory would reach her deceased father on earth or in heaven.
A swordsman from a severely impoverish land, he became a mercenary to provide for his family. Born with superhuman dexterous hands, he developed his "Sword-Juggling Style", eventually becoming infamous enough to cause soldiers to flee in fear from him. A scheming general, hoping to defeat the swordsman, bribed a comrade-in-arms of the swordsman to poison his evening meal. After three days and nights of agony, he survived at the expense of his arms and legs becoming crippled. He quickly fell into despair, as his reason for fighting had changed from providing for his family to perfecting his technique. The Chalice appeared before him as he was about to throw himself into the sea. He sacrificed the family he once cared for in return for the technique he lost. Snake-like appendages erupted from his stomach, turning his technique into the "Nine Sword Juggling" style.
Fallen Hero: He was once a hardworking man trying to provide for his family.
Green Thumb: He can poison anyone with his tentacles and cover the map in a purple mist, requiring a venomous armor to prevent being poisoned.
The Ghost: It's directly stated that a version of the Slime for The Lustful exists, and it's implied there's a version of the slime for every type of Archfiend, but we only see the ones for The Greedy and The Gluttonous.
Hellhound: Subverted. This Cerberus, despite being the usual tri-headed dog, differs by being capable of Shock and Awe and by being born from the Fusion Dance between a guardsman and his two hunting dogs.
Shock and Awe: Most of his attacks involves this. Let it be from the spear in his chest, his other heads...
The Jailer: He was so obsessed with protecting his town that he ultimately became this when he prevented the townspeople from leaving despite the deadly outbreak.
Green-Eyed Monster: Both figuratively and literally. The literal part, she had her father's Green Eyes, which was a trait of his lineage. The figurative part comes in that all she ever wanted was a loving family, which the Duke and his wife never let her have.
Royal Bastard: She was the result between an affair between a Duke and one of his maids.
