In a v1.0.1 evaluation, megad16 reports that Pacifist reduces damage dealt by 50% and required evolution Progress by 33%. megad16 · v1.0.1 review
Pacifist's current unlock condition has not been independently confirmed. Check its locked Genetics card; selecting this genetic and completing a no-damage achievement are separate goals.
Decide whether the run needs your own damage. A lower Progress requirement can reduce the food needed for an upgrade, while weaker attacks can make a damage-dependent boss plan harder.
Reduced damage is still damage. Dove requires a win with no damage dealt; Zen requires a win with neither damage dealt nor damage taken. Steam achievement condition Choosing Pacifist alone satisfies neither condition. A lower Progress requirement also describes the cost of evolving, not an increase to the value of every food item.
The June 3 player evaluation supplies the two reductions for v1.0.1. It does not confirm the unlock or make damage dealt disappear. Steam lists Dove and Zen as separate achievement goals.
: Added questions covering “What tradeoff should guide the next Evolution choice?” and “Does choosing Pacifist satisfy Dove or Zen?”. The answers clarify the relevant choice while preserving the stated conditions, distinctions and attribution to the original sources.
