Character Compatibility

Species match is determined first.

Same species → 100%
Different species → 50%
If either species is a hybrid → 25%, unless both characters share the exact same hybrid species, which stays 100%.


Species Forced is gained through consecutive days of receiving that species’ semen by copulation or insemination.
The required number of days is:

min(Growth Period, Ovulation Cycle)

Completing that full streak results in 100% forced compatibility with that species.


Class and Form modify the species match using their complexity values.
The compatibility factor uses the lower value divided by the higher value for both Class and Form:

(class_low / class_high) * (form_low / form_high)

  • Human — 1.0
  • Demon — 1.2
  • Daemon — 1.5
  • Deity — 2.0
  • Synth — 100.0
  • Digital — 500.0
  • Human — 1.0
  • Feral — 0.8
  • Anthro — 0.9
  • Taur — 1.1
  • Shift — 1.2
  • Monster — 1.3

Two characters share the same species and both are Feral.
One has a Human class (1.0) and the other has a Daemon class (1.5).

Base compatibility:

100 * (1.0 / 1.5) * (0.8 / 0.8) = 66%

Breeding Forests and Partners can each add up to 50% of the remaining incompatibility.

Using the previous example:

  • Remaining incompatibility: 34%
  • Partner bonus (100% partner compatibility): 17%
  • Final compatibility: 83%
