Familiar Fusion

How to choose parents, tune a chamber, use Catalysts, and read a Fusion result.

Updated July 20, 2026

Before you fuse

Fusion is the discovery side of the familiar system. Pick two familiars, inspect their possible inherited traits, and choose a Calibration that shapes how the chamber resolves them.

Fusion loop

  1. 1Pick parentsChoose two familiars whose genes, visual traits, or family lines you want to combine.
  2. 2Choose a CalibrationCalibrations are reusable chamber settings that shape the possible genetic result.
  3. 3Add a Catalyst if usefulA Fusion Catalyst can recall an eligible outcome you previously claimed from the selected pairing. It is consumed when Fusion starts.
  4. 4Return and claimThe experiment continues while you leave. Claim the completed familiar to record its genes and lineage.
  5. 5Use Reverb carefullyA matching Reverb Catalyst can split a claimed Fusion result back into fresh copies of its original pair.

Where to go

FAQ

Can I fuse familiars I have not researched?
Yes. Research is not required. Because research consumes its subject, use existing Almanac knowledge and gene reports rather than researching a parent you intend to fuse.
What does Fusion consume?
Starting a standard Fusion consumes both parents and any optional Fusion Catalyst. Calibrations are reusable and are not consumed.
