OnceWas Core Rule Book
A downloadable Rule book
🌙 OnceWas: A Tabletop RPG of Wonder, Peril, and Quiet Magic
OnceWas is a tabletop role-playing game where adventure beckons from shadowed forests, forgotten ruins, and locked doors that promise wonder and danger in equal measure.
🎲 A Single, Elegant Core Rule
At the heart of OnceWas lies one clear principle:
Roll a d20—and roll high.
Every challenge—
-
swinging a sword,
-
resisting a curse,
-
picking a stubborn lock,
-
leaping across a chasm—
uses the same unified mechanic:
Roll a d20, add modifiers, meet or exceed the target number.
This keeps gameplay swift, consistent, and intuitive, without sacrificing depth.
⚔️ Rebalanced for Modern Play
OnceWas rebuilds classic fantasy mechanics for today’s players:
-
Seamless flow between combat and exploration
-
Skill checks and spellcasting designed to feel natural together
-
Smoother, clearer rules with inconsistencies removed
-
Faster pacing that keeps the spotlight on the story at your table
🌟 For Newcomers and Veterans Alike
OnceWas welcomes new players with easy-to-learn mechanics, while offering veterans a familiar yet refreshed experience.
The rules feel instinctive, the pace stays brisk, and every moment points toward what truly matters—
the adventure your group shapes together.
