How this works
The list, names and descriptions come from the achievement data Steam publishes for Hollow Knight: Silksong; the unlock rates are Steam's global figures as of 2026-10-19. Rarity tiers: common 40% and up, uncommon 15–40%, rare 5–15%, very rare under 5%. Links to our pages (23) are added only where the achievement text names the thing exactly.
