Mage M20 GM checklist cheat sheet

Before-session and during-session reminders. At-the-table reference for Mage: The Ascension 20th Anniversary.

Mage M20 GM checklist: reality is subjective, Paradox is the pressure valve, and every Tradition sees the world differently.

Before the session
  • Know each PC's paradigm: what magic looks like to them.
  • Decide what counts as coincidental in this scene (context-dependent).
  • Prep 1-2 Paradox consequences if players go vulgar.
  • Plan a mix of magical and mundane challenges.
During play
  • Ask players to describe their magic: paradigm is not optional flavor.
  • Track Paradox pools: backlash should feel inevitable, not arbitrary.
  • Sleeper witnesses make vulgar magic worse: use crowds as a tactical element.
  • Technocracy and Nephandi are threats that can't be punched away.
Common mistakes
  • If Paradox never matters, players will always go vulgar.
  • Coincidental vs vulgar should be a genuine choice, not a tax.
