Nibble. Discovery. Card Pack.
Answer an Encounter to earn a Nibble. Gather the required Nibbles to complete a Discovery. Every completed Discovery unlocks a Card Pack.
Every Nibble moves something forward.
Complete an Encounter and earn Nibbles towards a specific Discovery. Perfect play can add a bonus, while the final Nibble unlocks the Discovery and its rewards.
Short sessions. Clear feedback. Progress you can see.

Discoveries become a collection.
Completed Discoveries fill the Index and unlock Card Packs. Cards support sets, duplicates and favourites, giving learners a longer goal beyond a single question.
Collection sits above the learning loop. It does not replace it.

Some knowledge deserves a reveal.
Discovery variants, rarity and card details turn progress into a personal collection. Repeat play can unlock new finishes after the core knowledge has already been learned.
Standard, Prismatic, Nocturne, Golden, Verdant and Waypoint variants are part of the current design.
