Cheat sheet
GM checklist (Mage: The Ascension 20th Anniversary)
Before-session and during-session reminders.
Quick blocks
Mage M20 works when paradigm is respected: the question is ‘how does this make sense in your worldview?’ and ‘what does Paradox cost you?’
Session checklist
- Ask for intent + method (paradigm) before mechanics.
- Encourage Coincidental effects as the default.
- Track Paradox as a consequence engine, not a punishment.
- Keep rulings consistent so players can be creative safely.
Common pitfalls
- Unlimited magic with no cost
- Inconsistent rulings
- Skipping paradigm and going straight to mechanics
