Spellcasting

Lore & Background

In the Shadowrun setting, magic is not a relic of a forgotten age—it is a living, contested force that reasserted itself in the early 21st century alongside the rise of cybernetics. Mages are born with the ability to perceive and shape the magical aether, and their training in the various schools of magic (often tied to the elemental traditions of fire, air, water, and earth) gives them a toolkit that no amount of chrome can replicate. A well-prepared mage can turn a corporate security checkpoint into a wall of flame, shield a team from a sniper's round with a layered Ward, or call down a bolt of Lightning that makes the most expensive smartgun look like a toy.

Yet the Shadowrun world is built on a fundamental tension between magic and technology. Cyberware is the 'hard system': quantifiable, upgradeable, and reliable. Magic is the 'soft system': powerful, versatile, and inherently uncertain. A street samurai with a military-grade smartgun and reactive armor will always land their shots; a mage with a 9 Magic rating and a well-chosen Lightning spell might obliterate the same target in one breath—or might fumble the roll, take 4 points of Drain, and watch the bolt arc back into their own face. This asymmetry is not a bug in the design; it is the entire point. Shadowrun asks the player to weigh the cold certainty of chrome against the wild, narrative potential of a well-timed incantation.

The distinction between Mages and Adepts further enriches the lore. Mages cast spells in the moment, rolling dice under pressure and accepting the full risk of Drain and Backlash. Adepts, by contrast, have their spells 'pre-cast' into Powers—fixed, always-available abilities that cost no dice to activate but offer far less flexibility. A mage can adapt a Fireball into a defensive wall or a focused beam; an adept's equivalent Power simply does what it does. This creates a rich tactical and roleplaying contrast at the table, and it mirrors the broader Shadowrun theme that the most powerful tools come with the heaviest strings attached.

In Their Own Story

The rain on the 47th floor hit the glass like static. Kira pressed her palms flat against the window, feeling the aether hum beneath the storm—thick, electric, tasting of copper. Three corporate guards in full tactical gear were stacking up on the landing below, smartguns hot, optics glowing red in the dark.

She didn't draw a weapon. She never did. Instead she let her Magic pool settle in her chest, nine d6s worth of potential, and she whispered the incantation the way her mentor in the Ashari school had taught her: not a shout, not a command, just a permission given to the air itself to remember what it was before the sky was paved over.

The Threshold was six hits. She needed six.

She rolled. The dice clattered in the invisible space behind her eyes. Five. Four. Six. Three. Five. Two. Seven. One. Five.

Five hits. One short. The Drain hit her like a fist to the sternum—three points of flesh tearing, hot and immediate. The Lightning didn't come. The guards pushed through the door.

Kira spat blood, reset her pool, and whispered the incantation again. This time she added Willpower. Eleven dice. The Threshold was still six.

She rolled.

This time the sky remembered.

Reader's Guide

Casting a spell in Shadowrun follows a clear sequence, but the tension comes from the risk layer stacked on top of the roll.

1. Determine your pool. Your base pool is your Magic rating. You may add your Willpower to the pool, but you cannot exceed the spell's Base Dice plus your Willpower. This cap prevents a high-Magic character from trivially auto-casting every spell.

2. Roll the d6 pool and count hits (5s and 6s). Compare your total hits to the spell's Threshold. Meeting or exceeding the Threshold means the spell lands as described.

3. Failure and Drain. If you fall short of the Threshold, the spell does not activate, and you take the spell's listed Drain as damage to your body. This is the core risk: a failed Fireball doesn't just miss—it hurts you.

4. Backlash. If you roll zero hits on the entire pool, the spell catastrophically backfires. The Backlash entry on the spell card describes what goes wrong—often the spell's effect is redirected at you or a nearby ally. This is the worst-case outcome and the reason experienced players sometimes choose not to cast at all.

5. Concentration and damage. If you take damage while in the middle of a casting sequence (or while maintaining a sustained spell), you may be forced to make a Concentration check or lose the effect entirely. This makes mages fragile in sustained firefights and rewards positioning, cover, and team support.

What makes this distinct from other d6 or cyberpunk TTRPGs is the deliberate 'soft system' framing. The rules give you the dice, the Threshold, and the Drain, but the GM is explicitly encouraged to narrate the spell's effect in creative, scene-specific ways. A Lightning spell might not just deal damage—it might shatter the smartgun in a guard's hand, short out the elevator, or arc through a wet floor and take out two more enemies. In a game like Cyberpunk RED or other d6 cyberpunk systems, magic (if present) tends to be a fixed damage number. In Shadowrun, it is a narrative event with a dice check attached, and that difference is the entire identity of the magic system.

Did You Know?

• Shadowrun's magic is explicitly designed as a 'soft system'—the rules provide the dice framework, but the GM is encouraged to narrate spell effects creatively, making two casts of the same spell play out very differently
• Adepts and Mages use the same underlying magical energy, but Adepts 'pre-cast' their spells into fixed Powers that require no dice roll to activate, trading flexibility for reliability—a design choice that creates a deli
• The Drain and Backlash mechanics mean that a failed spellcast is not merely a wasted turn; the caster takes real damage or suffers the spell's effect turned against them, making magic one of the most personally risky act
• The distinction between Mages (who cast spells in the moment under pressure) and Adepts (who hold permanent, always-available Powers) mirrors the broader Shadowrun theme that the most powerful tools carry the heaviest st
