Base Stat Note

This mod defines trait multipliers, XP leveling, and passive talent behavior. Base species HP/damage/speed values come from the role assets they inherit from. Use this page to understand the modifier ranges your lines can roll and inherit; leveling and talents add modest long-term bonuses on top of those inherited base stats.

Breeding Strategy

  1. Keep your best breeder pairs separated and protected.
  2. Replace average breeders with offspring that improve priority traits.
  3. Avoid blindly maximizing every trait; pick role-specific goals.
  4. Track line outcomes over several generations before pruning.
