Create rotes (codified magical effects) for Mage: The Ascension 20th Anniversary Edition (M20). Design mechanically balanced rotes with appropriate Sphere requirements, Practice associations, and paradigm-consistent flavor. Requires mage-rules-reference skill for Sphere/Practice/Ability lookups. Triggers: create a rote, design a magical effect, M20 rote, need a rote for [Tradition/Convention].

Rote Creator

Design mechanically valid, thematically rich rotes for M20.

What is a Rote?

A rote is a magical effect practiced and refined to the point where it can be performed identically every time. Benefits over improvised magick:

  • Roll Attribute + Ability instead of Arete
  • More consistent results
  • Defined mechanical parameters

Creation Workflow

1. Clarify Intent

What effect does the mage want to achieve? Be specific about scope, target, and duration.

2. Determine Sphere Requirements

Query mage-rules-reference for guidance:

bash
# What Spheres for a standard effect?
python lookup.py references/common-effects.json "Telepathy"

# What can Forces 3 do?
python lookup.py references/sphere-levels.json "Forces"

# Find effects involving a Sphere
python lookup.py references/common-effects.json --find "Life"

Sphere Level Guidelines:

  • 1 (Initiate): Perception, sensing
  • 2 (Apprentice): Minor manipulation, self/willing targets
  • 3 (Disciple): Significant effects, affect others, temporary patterns
  • 4 (Adept): Major transformations, permanent effects
  • 5 (Master): Create from nothing, large-scale, perfect control

3. Assign Practice

Select a Practice fitting the mage's paradigm. Query associations:

bash
# What abilities work with this Practice?
python lookup.py references/practice-abilities.json "High Ritual Magick"

# What practices does this faction use?
python lookup.py references/faction-practices.json "Virtual Adepts"

The mage's Practice rating must ≥ highest Sphere level in the rote.

4. Design Execution

  • Choose instruments fitting the Practice
  • Describe how the rote is performed
  • Consider paradigmatic explanation

5. Determine Dice Pool

Select Attribute + Ability where:

  • Ability is associated with the chosen Practice
  • Combination makes sense for the effect

Common patterns:

  • Perception effects: Perception + Awareness
  • Combat effects: Dexterity + Ability or Wits + Ability
  • Ritual effects: Intelligence + Occult/Esoterica
  • Social effects: Manipulation + Expression/Subterfuge

6. Calculate Rote Cost

Cost = Total Sphere dots

Example: Life 3, Prime 2 = 5 points

  • Characters begin with 6 points of rotes
  • Additional: 4 Freebie Points or 3 XP per point
  • Learning from teacher/grimoire: Half cost (requires source rating > highest Sphere)

7. Assess Paradox Risk

  • Coincidental: Explainable by Sleeper logic, minimal risk
  • Vulgar without witnesses: Moderate risk
  • Vulgar with Sleeper witnesses: High risk

Provide guidance on making effects more coincidental when possible.

8. Write Description

See references/output-template.md for format.

Validation Checklist

  • Sphere levels match effect scope (not over/under-powered)
  • Practice is appropriate to paradigm
  • Ability is associated with chosen Practice
  • Dice pool makes sense for the action
  • Paradox assessment is accurate
  • Foci fit the tradition
  • Effect doesn't obsolete existing canon rotes without reason

Key Principles

Balance First: Useful without being game-breaking

Paradigm Matters: A Virtual Adept's hack looks nothing like a Verbena's nature working achieving the same end

Avoid Sphere Creep: Don't require more Spheres than necessary

Simple Effects Stay Simple: Don't overengineer basic magic

Conjunctional Effects

When combining Spheres:

  • Primary Sphere determines the main effect
  • Secondary Spheres extend reach, add properties, or enable the effect
  • Highest Sphere level sets the baseline difficulty
  • More Spheres = more versatile but higher cost

Common conjunctions:

  • Correspondence + X: Affect at distance
  • Prime 2 + X: Create patterns, add aggravated damage
  • Time 4 + X: Trigger effects, delay effects
  • Spirit 3 + X: Affect across Gauntlet
