Successfully navigating the Index Proxy encounters, and by extension, truly understanding the challenge Moirai represents, requires a comprehensive mastery of Library of Ruina's intricate combat system. It's less about a single "silver bullet" strategy and more about adapting, anticipating, and optimizing your Library's resources. 1. Understanding the Index's Core Mechanics: The Index Proxies often employ the "Shimmering" passive, which can make them harder to hit or allow them to manipulate dice. They also have cards like "Binding Chains" which reduce your dice power on clash, and "Unlock" pages that become more powerful after certain conditions are met. Some of their key pages might have strong initial rolls or inflict specific debuffs. Your primary goal should be to prevent them from achieving their favorable conditions, especially their power-reducing effects, by winning crucial clashes. 2. Deck Synergy and Consistency: In Library of Ruina, the preparation phase—deck building and passive attribution—is arguably more crucial than in-combat execution. * Light Economy: Ensure your decks have sufficient light restoration (e.g., "Wait Up!" which guarantees an emotion coin and restores light) and page draw (e.g., "Flash of Sunup" or "Rules of the Backstreets"). Running out of light or cards can be a death sentence against sustained pressure. * Speed Dice: Key pages with multiple Speed dice are invaluable, especially in the late game. This allows your Librarians to act more frequently and control the flow of clashes. Attributing Speed passives if a key page lacks them is also a common strategy. * Balanced Costs: Avoid decks with only high-cost cards. A mix of 1-cost, 2-cost, and 3-cost pages provides flexibility. Low-cost pages are crucial for activating certain passives or maintaining hand presence, while high-cost pages deliver significant impact. * Power Infusion: Look for passives and combat pages that grant power, such as "The Strongest" or "M Prowess." These can turn even mediocre dice rolls into winning clashes. Building around singular, powerful attacks or ensuring consistent power buffs can be incredibly effective. 3. Prioritizing Clashes and One-Siding: Not every clash needs to be won. Sometimes, it's more beneficial to "one-side" an attack (allocate all your dice to a single target) if you know you'll lose a clash, especially against attacks with disruptive effects. This saves your speed dice for more critical clashes. However, against the Index Proxies, whose debuffs can cripple your team, winning key clashes to negate their effects is often paramount. Utilize block dice strategically to absorb damage or gain stagger damage if you win. 4. Staggering Opponents: Staggering enemies is a primary objective in Library of Ruina as it renders their resistances "Fatal," doubling all damage. Identify the Index Proxies' stagger weaknesses (blunt, pierce, or slash) and focus damage accordingly. Pages that inflict bonus stagger damage can accelerate this process. Once an enemy is staggered, unleash your strongest attacks to quickly finish them off before they recover. 5. Emotion Level Management: Gaining Emotion Levels is critical. Winning clashes, rolling minimum/maximum dice values, and killing enemies grant Emotion Coins. Reaching higher Emotion Levels restores light, increases light capacity, and at Emotion Level 4, grants an additional speed die. At Emotion Level 5, you draw an additional page if you play at least two combat pages in a scene. Actively managing and manipulating Emotion Levels can provide significant advantages, especially during longer encounters. 6. Abnormality Pages and EGO: For Floor Realizations and later encounters, Abnormality Pages and EGO pages become game-changers. Each floor has unique Abnormality pages that synergize with specific damage types or playstyles. For instance, certain pages can provide sustain (e.g., "Echoes from the Beyond," "Pebble," "Laughing Powder"), while others offer immense offensive power. EGO pages are floor-specific combat pages that can turn the tide of battle, often at the cost of sanity or negative emotion coins. Mastering the use of these powerful tools is essential for high-difficulty receptions. 7. Key Page Selection and Attribution: The Key Pages you choose and the passives you attribute to them form the backbone of your strategy. Players often combine powerful Key Pages like the Red Mist (for high power), Purple Tear (for stance-switching versatility), or even specific Index Proxy key pages after acquiring them, with passives from other characters to create devastating builds. For instance, combining "Myongest" on Red Mist with "Smoke" passives can lead to incredible damage output. Experimentation is key to finding synergies that click with your playstyle. In essence, defeating the Index Proxies is a microcosm of Library of Ruina's overall design philosophy: a demanding but deeply rewarding challenge that pushes players to think critically about their decks, understand enemy patterns, and adapt on the fly. It's a dance with destiny, where your strategic choices are the only means of carving out your own victory.
