About Library Of Ruina
"May you find your book in this place." Combat between the guests and the librarians breaks out as if it were on a stage. Defeated guests turn into books, and the Library grows onward. And eventually, get your hands on… The one singular, perfect book.
How rarity is calculated
Each platform calculates rarity from its own player population. These percentages are shown side by side but are not a controlled comparison.
- Steam — Valve's published global unlock percentage across Steam owners of the game.
Percentages are shown exactly as each platform publishes them. Pyroblast does not recalculate them and does not mix player populations together. Data updated .
