Abnormality Pages
| Abnormality Pages | ||
|---|---|---|
| The Queen of Hatred | ||
Lv Ⅰ  1  Love |
[Single Ally] After winning a clash using an Offensive die, a random ally recovers 3-5 HP. After winning a clash using a Defensive die, a random ally recovers 2-4 Stagger Resist. In the name of Love and Justice~ Here comes Magical Girl! |
|
Lv Ⅰ 0  Justice |
[Single Ally] The enemy who dealt the most damage to allies on the previous Scene is marked as a ‘Villain’. Deal +3-5 damage when attacking the ‘Villain’. If I am on the side of good, then someone has to be on the side of evil. Without someone to play the villain, I can’t exist. |
|
Lv Ⅰ  -1  Hate |
[Single Ally] After losing a clash, take 2-4 Stagger damage, and gain 1 Strength next Scene. (Up to 2 per Scene) After losing three clashes in a single Scene, reduce the Cost of the most expensive page in hand by 1. (Once per Scene) She vowed to love everything in the world, but all that was left was a collapsing heart. |
|
| The Knight of Despair | ||
Lv Ⅰ -1  Blessing |
[Single Ally] If the character took damage from attacks on the previous Scene, change this character’s resistances against the type that dealt the most damage to Endured for the Scene. (Applies separately for physical and Stagger damage) The will to protect seems to remain unchanged after all this time; even in containment, it is still obsessed with the act of protection. |
|
Lv Ⅰ 2  Blades Whetted by Teardrops |
[Single Ally] On a successful Pierce attack, if the die rolled max. value, deal bonus damage equal to 10% of the target’s Max HP. (Max. 12, Excludes Mass Attacks) When Justice turns its back once more, several dozen blades will rove without a purpose. The swords will eventually point at those she could not protect. |
|
Lv Ⅰ -2  Despair |
[All Allies] Whenever an ally dies, all other allies gain 1-3 Strength and Haste, and all enemies are inflicted with 2 Fragile. As with sorrow, perhaps sharing the burden will blunt the edge. |
|
| The King of Greed | ||
Lv Ⅱ 2  Intemperance |
[Single Ally] If the first die of a Combat Page wins a clash, destroy all remaining dice the opponent has at a 25% chance. The first seed of desire originated from the pure yearning for happiness. The tiny seed grew larger and larger, hungering for more. Over time, the seed hardened and turned into a piece of shiny gem. |
|
Lv Ⅱ 1  Road to Happiness |
[Single Ally] Gain 1 Endurance for each clash won in a Scene. (Up to 3 per Scene) Happiness became obsession, obsession became greed, and the greed forever solidified to become a golden amber. The happiness in the beginning, still holding a smile, dwells inside. |
|
Lv Ⅱ -1  Greed |
[Single Ally] In a clash, if the winner’s dice roll is greater than the loser’s by 4 or higher, the loser takes 3-7 bonus damage, and the winner recovers 2-5 HP. (Both the librarian and their opponent can activate this effect) The magical girl, who was no longer a magical girl, ate many things. Authority, money, fame, and many other forms of pleasure. She ended up eating away anything in her sight. Now, only visceral greed remains. |
|
| The Servant of Wrath | ||
Lv Ⅱ -1  Wrath |
[Single Ally] The selected librarian enters a state of Wrath. The librarian will become uncontrollable and target random characters, including allies. Also, the librarian gains 2 Strength, restores 2 Light, and draws 2 more pages each Scene. The Servant was betrayed after abandoning her principles and ingenuously trusting someone with her whole heart. Now, she is dominated by the anger towards herself for what she had done. |
|
Lv Ⅱ 0  Companion |
[Single Ally] When there is no ‘Companion’ present, the first enemy the selected librarian hits is marked as one. When the selected librarian defeats the Companion, all librarians restore 3 Light and recover 10 HP and Stagger Resist. The Servant of Wrath valued justice and balance more than anyone, but she began sharing knowledge with the Hermit—an enemy of her realm—becoming friends with her in secret. |
|
Lv Ⅲ 1  Acidic Sludge |
[All Enemies] Inflict 5 ‘Erosion’ to all enemies. Enemies with Erosion also gain Bind equal to the amount of Erosion they currently have. (Erosion: At the end of the Scene, take damage equal to the amount of Erosion and lose 1 stack; when taking a hit, take bonus damage and Stagger damage equal to the amount of Erosion.) When the two met at last, the Hermit brought countless minions to destroy the Servant’s world. |
|
| The Jester of Nihil | ||
Lv Ⅱ -2  Magical Girls |
[Single Ally] At the start of the Scene, a Combat Page in hand with the highest Cost (that is lower than 4) is marked with a Magical symbol. After losing 4 clashes with the marked page, gain 5 Protection each Scene, and become immune to status ailments for the rest of the reception. Also, when hit, inflict 1 Erosion and Fragile next Scene to the attacker. (Twice per Scene) The jester retraced the steps of a path everybody would’ve taken. The jester always found itself at the end of that road. There was no way to know if they had gathered to become the jester, or if the jester had come to resemble them. |
|
Lv Ⅲ -1  Void |
[Single Ally] Add an ‘All Returns to the Void’ page to the hand: ‘Cost 3 - [Single-use;][Combat Start] Exhaust all pages from hand. Every Scene after this, gain Strength and Endurance equal to the number of pages exhausted this way.’ The page is also included in the deck at the start of subsequent Acts. The jester was deeper in thought, that poor jester. Without the brave puppy to lead the way, it walks with meaningless steps. |
|
Lv Ⅲ 0  Nix |
[Single Ally] This page is only effective if the librarian possesses all four of the following Abnormality pages: ‘Greed’, ‘Hate’, ‘Despair’, and ‘Wrath’. At the start of the Scene, inflict 5 Feeble, Disarm, and Bind to all other characters. ‘Greed’, ‘Hate’, and ‘Wrath’ lose their drawbacks. Having decided to trust its own intuition, the jester spake the names of everyone it had met on that path with each step it took. |
