Stormbringer:Sorcery
Sorcery

In the world of Stormbringer, sorcery is an act of will. The sorcerer calls something into the world, binds it, commands it, and then struggles to keep it contained. Every working follows the same pattern:
Summon → Bind → Command → Endure
There are no spell lists. All effects come from bound beings.
The Sorcery Roll
To summon and bind a being:
2d6 + Mind + appropriate Career
The Career must reasonably apply (Sorcerer, Witch, Priest, Demonologist, etc.).
Difficulty is based on Magnitude:
| Magnitude | Being | Difficulty |
|---|---|---|
| I | Elemental | 9 |
| II | Demon | 12 |
| III | Ruler / Named Power | 15+ |
Success binds the entity. Failure means something arrives—but is not controlled.
Time and Ritual
Sorcery takes time.
| Magnitude | Time Required |
|---|---|
| I | 3d6 minutes |
| II | 1d3 hours |
| III | Hours to days |
Rushed Working
- Reduce time by one step
- Gain +1 Penalty Die
- Increase risk of Doom
Extended Ritual
- Increase time by one step
- Gain +1 Bonus Die
- Reduce Doom risk
Interruptions force an immediate roll at +1 Penalty Die or the working collapses.
Degrees of Binding
- Bare Success — Bound, but resentful and unstable
- Strong Success — Stable control
- Mighty Success — Firm control, reduced escape risk
Magnitudes of Sorcery
Magnitude I — Elementals
Spirits of fire, air, earth, and water.
Used for:
- Direct physical effects (burning, lifting, flooding)
- Environmental manipulation
- Simple enhancement
Magnitude II — Demons
Intelligent, willful beings defined by function.
Common types:
- Demon of the Blade
- Demon of Knowledge
- Demon of Shadow
- Demon of Protection
- Demon of Strength
- Demon of Desire
They interpret commands and seek advantage.
Magnitude III — Named Powers
Elemental Lords, Demon Princes, and other unique beings.
These are not tools, but events.

- +1 Bonus Die to an action

Magnitude III Effects
Storms, destruction, transformation.
Handled narratively, not mechanically.
Escape and Strain
Bound beings resist.
At intervals, roll:
2d6 + Magnitude
On 13+, the binding strains.
| Result | Effect |
|---|---|
| 13–14 | Strain (twisted commands) |
| 15–16 | Partial break (act independently) |
| 17+ | Escape (fully free) |
The sorcerer may attempt to reassert control:
2d6 + Mind + Career
Failure worsens the result.
Binding Limit
Maximum simultaneous bindings:
Mind + Sorcerer Career Ranks
Each active effect counts as one binding.
Exceeding the Limit
For each binding beyond limit:
- +1 Penalty Die to Sorcery rolls
- +1 to Escape rolls
- Doom triggers on 1–3
Failure becomes catastrophic.
Doom
After each working:
1d6 → Doom on 1–2
Modifiers:
- +1 for Magnitude II
- +2 for Magnitude III
Doom represents attention and consequence:
- Whispers, dreams, marks
- Recognition by demons
- Loss of control
- Returning bargains
The Nature of Sorcery
Sorcery is not fast.
It is not safe.
It is never casual.
A sorcerer does not cast spells.
He holds shut a door.
And something on the other side is always pushing.
