Between rhythm stages, In Falsus is a card builder. The card integration system is where your long-term power comes from, and it's easy to sabotage yourself without noticing. Here's how every piece fits together, based on the public demo.
The loop at a glance
- Collect Iota — clear Encounters at Connected + Dive Clear or better to earn Iota materials.
- Fill a Blueprint — place Iota on a hexagonal grid to unlock the card's base stats.
- Select Traits — pick special abilities from your unlocked Trait Slots.
The output is a Card with Power, Defense, a color, and up to several Traits — the deck you take into future Encounters.
Iota: colors, shapes, tiers
Iota come in five colors and a range of shapes. Each Encounter has a fixed drop pool — typically 12 kinds (4 colors × 3 shapes) of a single Tier as of demo v0.3.0 — so if you need a specific color/shape combination, you farm the Encounters whose pool drops it. Beyond color and shape, each Iota has:
- Tier — higher tiers contribute bigger numbers
- Potency — the raw stat value the piece feeds into the card
Color, Tier, and Potency together determine the final card's Power and Defense.
Blueprint placement rules
The Blueprint is a hexagonal board containing one or more colored Zones. Each Zone you fill adds base Power, Defense or Trait Slots. The catch is the penalty system — four ways a placement can go wrong:
| Penalty | Trigger |
|---|---|
| Overload | Exceeding the Iota Limit |
| Out of Bounds | Placing on an unsafe cell |
| Overlap | Multiple Iota on one cell |
| Disconnect | Iota group not connected |
Penalties don't subtract a little — they scale your entire card:
- 0 penalties → 100% stats
- 1 penalty → 89%
- 2 penalties → 56%
- 3 or more → 0% — the card is dead weight
Always do a final penalty check before integrating. Some characters have Tolerance skills that ignore specific penalties, which opens up placements that would otherwise be illegal — this is the deepest optimization lever in the demo.
The color advantage cycle
Cards and Encounters have colors, and colors beat each other in a cycle:
Red → Green → Purple → Yellow → Blue → Red
The advantaged side gains ×1.25 Power and Defense. When choosing which five cards to bring into an Encounter, color matchups are worth more than raw stats in most cases — a weaker card with advantage often out-damages a stronger neutral one.
Traits
Trait Slots unlock as you fill the Blueprint. Traits are the strategic layer: some restore Resolve (your survival resource) mid-Encounter, others boost damage output. A balanced deck usually wants at least one Resolve-recovery Trait for longer Encounters.
Practical build order
- Decide the color you need for the target Encounter (check the cycle above).
- Farm Iota from Encounters whose drop pool matches.
- Fill the Zones with your highest-Potency pieces, zero penalties first, stats second.
- Re-integrate the same Blueprint with different configurations — integration isn't one-shot, though each run consumes the Iota you place, so plan placements before committing rare pieces.
