# Output: Forces: Fiery, Bright, Energetic, Stormy, Electric, Kinetic

Type-Specific Rules
Talismans
The most sophisticated Wonders—permanent items with independent magical capability.
| Stat | Value |
|---|---|
| Powers | = Rank (one power per rank) |
| Arete | 1-10 (typically ≤ Rank) |
| Quintessence | Rank × 5 |
| Power Limit | No power's Sphere level > Arete |
Power Design: Use rote-creator skill for each power. Each power needs:
- Sphere requirements
- Effect description
- Activation method
- Quintessence cost (if any)
Artifacts
Single-power permanent Wonders. Simpler than Talismans.
| Stat | Value |
|---|---|
| Powers | 1 |
| Arete | None (uses wielder's or fixed dice) |
| Quintessence | Optional storage |
| Rank | = Highest Sphere level in effect |
Power Design: Use rote-creator for the single effect.
Charms
One-use Wonders destroyed after activation.
| Stat | Value |
|---|---|
| Powers | 1 |
| Arete | = Rank (rolled on activation) |
| Rank | = Highest Sphere level |
| After Use | Destroyed, inert, or transformed |
Common Forms: Potions, scrolls, talismans (broken), bullets, gadgets (burn out)
Periapts
Quintessence storage devices. May have secondary powers.
| Stat | Value |
|---|---|
| Max Charges | See table below |
| Consumable | Yes (like Tass) or No (refillable) |
| Secondary Power | Optional |
Capacity by Rank:
| Rank | Max Charges |
|---|---|
| 1 | 5-10 |
| 2 | 10-20 |
| 3 | 20-30 |
| 4 | 30-50 |
| 5 | 50-100 |
Charging Indicators: How does charge level show? (Glow, warmth, weight, color, hum)
Creation Workflow
- Type: Talisman, Artifact, Charm, or Periapt?
- Concept: What is it? Who made it? What paradigm?
- Rank: Based on power level / capacity
- Powers: Use rote-creator for each effect
- Resonance: Traits totaling ≥ Rank (query mage-rules-reference)
- Physical Form: Appearance matching paradigm
- History: Origin, wielders, legends
- Validate: Check type-specific rules
Paradigm Forms
| Tradition | Typical Forms |
|---|---|
| Hermetic | Rings, wands, ceremonial objects, grimoires |
| Technocracy | Devices, implants, gadgets, programs |
| Verbena | Natural objects, blood items, living plants |
| Virtual Adept | Digital devices, interfaces, programs |
| Etherite | Ray guns, impossible machines, gadgets |
| Akashic | Meditation aids, martial implements |
| Celestial Chorus | Religious symbols, relics, icons |
| Dreamspeaker | Fetishes, spirit vessels, natural objects |
