CARDS & INTEGRATION

Card Integration is the core crafting mechanic in In Falsus used to synthesize and empower playable Cards. Players collect hexagonal Iota drops from cleared Encounters, slot them onto character-specific Blueprint grids, assign bonus Traits, and forge battle Cards whose Power and Defense scale with average Potency and determine encounter damage.

Cards unlock by progressing through the Scenario — the same way songs do. The full game lists 50 cards in total; the current demo (v0.3.0, April 2026) ships with two, Nia: Path to Reality and Mei: 4AM, plus the Card Integration menu that crafts more. The hub menu's Integration panel still shows locked entries, so the roster grows with the Scenario.

Older demo builds predate Card Integration and simply granted cards, which is why returning players ask where the extra cards went — the confusion has its own thread on the official subreddit. In the current demo, Scenario progression is the only path: r/InFalsus · How do y'all get other cards? ↗

Remembrance is the label the encounter screen gives each Dive's place in the story. On the loadout screen it sits under the Dive's name, beside the Difficulty Rating, as a number and an in-fiction calendar date: the Ghost Ray encounter “Unclear Dive” (Difficulty Rating 20) reads Remembrance 1 | 10276/8/27.

That date format matches the Scenario timeline in the hub menu, where chapter 1, “The First Lie”, is stamped Month 8, Day 28 — a Remembrance pins an encounter to a moment on the game's story calendar, year 10276.

The demo never defines the term beyond that label, and no written guide covers it yet — everything in this section comes from the video walkthrough cited under each screenshot.

Iota are the raw material of every card — hexagonal pieces that drop from cleared encounters. Each piece is defined by five attributes.

A Blueprint is the hex grid you build a card on. Three kinds of tiles matter.

From lowiro's official Card Integration & Encounter Showcase — the full craft-to-combat loop, frame by frame.

1. 1

   Slot Iota into the Blueprint grid

   Each piece covers the tiles under its shape. Here 2 of 6 Iota sit on Nia's Path to Reality: the covered Zones give Base Power 1,000 and Base Defense 400, Average Potency 110 makes a ×1.10 multiplier, and the penalty list reads all zeros — this layout keeps 100% of its stats.

   

2. 2

   Assign Traits and finalize

   On the Finalize Card screen, Iota carrying Traits fill the card's Trait Slots — this build slots Inner Concentration++ for Total POW +66% during the card's Phase. Hit Integrate to lock the craft.

   

3. 3

   Card obtained

   The finished Nia: Path to Reality comes out at 2,420 Power / 807 Defense — filled Zones times the Potency multiplier, with zero penalty reduction.

   

4. 4

   Build a 5-card loadout

   Before a Dive you link up to five cards into a loadout and the totals update live — this screen sits at 28,500 / 28,500 with slots still unlinked. Remember the rule: never two cards from the same Blueprint.

   

5. 5

   Connect in an Encounter

   The loadout faces the opponent across the chart: your Total Power burns their Resolve with every note you hit while their attacks chip yours. Outlast them to Connect — that is what pays Iota.

   

Four hard constraints govern every layout. Break one and you eat a penalty — sometimes without knowing it.

• Iota Limit — each Blueprint caps how many pieces you can place. Exceeding it triggers Overload.
• No rotation, no flipping — pieces go down exactly as they dropped. Plan around the shapes you own, not the shapes you wish you had.
• Maximum 3 Iota stacked per tile — a fourth piece on the same tile triggers Overlap.
• Power and Defense must both stay above 0 — a card with either stat at zero is not a legal craft.

Penalties multiply down your finished card's stats. Knowing what triggers each one is the difference between a 100% card and a 56% card.

Penalty scaling

Penalties stack multiplicatively against your card — at 3 or more, the card is worth 0% regardless of the Iota inside it.

Every crafted card's Power and Defense come out of the same calculation:

Three levers, in order of importance: keep penalties at zero (one mistake costs 11%, two cost 44%), hold your average Potency high, then fill as many colored Zones as the Iota Limit allows. In encounters, Total Power ÷ total notes sets your damage per note, and the Difficulty Multiplier (1.00 + Level × 0.05) scales the payout.

Colors beat each other in a one-directional cycle worth ×1.25 damage:

Red beats Green, Green beats Purple, Purple beats Yellow, Yellow beats Blue, Blue beats Red — and only in that direction. Attacking against the cycle gets you nothing. Check the encounter's color before you lock a loadout.

Traits are bonus effects carried by individual Iota, shown here in their strongest “++” variants.

Each of the five leads carries a named Blueprint with a signature color. Remember: a loadout can never contain two cards from the same Blueprint.

Infusion & Core Skills

A character's Infusion skill gates which Iota tiers you may slot per color — higher Infusion, higher usable tiers. Core Skills add tolerances that soften the placement rules, letting a layout get away with what would otherwise be a penalty. Level the character whose Blueprint color matches the Iota you actually farm.

The official September 11, 2026 post-launch patch (v1.0.3) adjusted the numeric thresholds for Card Crafting Mastery Challenges after players flooded the Steam community reporting near-impossible rolls on launch week. Below are 4 verified, 100% reproducible crafting setups designed to meet each adjusted threshold on your first attempt without relying on high-tier RNG farming.

Iota drop from cleared encounters. Each encounter has its own drop pool of roughly 12 Iota — 4 colors × 3 shapes, all at one Tier — so farming a specific piece means farming a specific encounter.

Drops require two conditions at once: the encounter must be Connected (win the Resolve race) and your run must be a Dive Clear or better (finish with HP at 0 or above). Full Link and Perfect Dive runs qualify; Dive Failed pays nothing.
