Defeat these creatures to add them to your codex
The Crucible
Creature Collection
Creature Codex
The Codex keeps track of what you have found. A new creature appears here as soon as you discover it, but it is not usable until you win its Challenger battle.
Beyond the Codex
There are things in the Lab that aren't counted among the 150.
Mastery
Every creature starts at Common Mastery. New successful Lab reactions and battles earn XP, and each rank also has its own challenge. Higher ranks unlock moves and can make some later recipes work.
My Creatures
Daily Discovery
Everyone gets the same formula for the UTC day. Missing a day does not cost anything, and the answer stays hidden until you solve it.
Mystery Formula
Choose two primordial samples
Daily Discovery
Research Desk
The first time a combination fails, or the first time you lose a specific Challenger battle, you still learn something and earn Research. Repeating either one pays nothing. Research can buy formula clues, Mastery training, and postgame clues.
Formula Analysis
Formula clues only point to reactions you can currently make with your unlocked creatures and catalysts.
Mastery Study
Spend Research to add XP to one creature. The creature still has to finish its rank challenge.
Mastery Forecast
Creatures worth training. No formulas given away.
Hidden Form Analysis
After the Codex is complete, Mythic-Mastered creatures can reveal clues about secret forms. Research can narrow those clues down to the exact ritual.
Secret Creature Analysis
After the Great Work, the Secret Archive can contain creatures outside the numbered 150. Research narrows vague leads while Archive Calibration and deeper Mastery determine when a reaction can actually hold.
Affinity Field Guide
Use this when you are choosing moves, planning a Challenger rematch, or building a Trial team.

Battles
Challengers unlock creatures you discovered in the Lab. Rival duels and the Dojo let you test teams, Lab Trials open later tiers, and roaming bosses can appear after enough real fights and drop Relics.
Your Team
0 / 3Up to three creatures. Edit from the Team button, or any creature's Codex page.
Dojo Practice
Pick the CPU team yourself, or leave slots on Auto and let the game fill them. Dojo fights give normal battle Mastery XP but no Research.
Picks a sensible opponent for you.
Lab Trials
The first creature in a new tier can be found normally. After that, pass its 3v3 Lab Trial before more recipes from that tier will work. A Trial can also unlock the next catalyst early.
Relic Vault
No battle in progress
Start a Rival duel here, challenge a newly discovered creature, or open Relics when a boss signal appears.
