Costs and Side Effects

Why Casting Costs Exist

Magic does not create energy from nothing.

Because it only channels, converts, and reshapes existing energy:

• something must power the spell,
• some portion is always lost,
• and the act of control itself imposes strain.

Cost is part of what magic is, not a price set on it afterwards.

Major Cost Types

The most common costs of casting include:

• bodily fatigue,
• heat loss or heat overload,
• pain,
• muscle and nerve strain,
• depletion of vital reserves,
• consumption of stored charge,
• environmental drain,
• social or ritual obligation,
• and increased risk of backlash.

Different schools emphasize different costs, but none escape cost entirely.

Personal Reserves

Many spells are paid for from the caster's own immediate reserve.

This can produce:

• tiredness,
• tremor,
• dizziness,
• headache,
• slowed thought,
• reduced coordination,
• or collapse.

This is the most familiar cost, and the one every apprentice learns first, usually by fainting. It is seldom the only one.

Lifeforce Expenditure

Some magic, especially healing and sacrifice-based workings, spends something deeper than fatigue.

When lifeforce or vital reserves are used directly, the result may be:

• shortened endurance,
• weakened recovery,
• premature ageing,
• vulnerability to disease,
• chronic frailty,
• or death.

This is one of the clearest reasons why restorative magic is not free.

Environmental Cost

Spells often take from the surrounding world.

Examples include:

• drawing heat from a room,
• draining moisture from air and soil,
• stripping vitality from local plant life,
• exhausting animal vitality,
• exhausting charged weather,
• destabilizing a ley-rich site,
• or burning through stored ritual works.

Folk can tell where a mage has camped: frost on summer grass, a hedge gone brown overnight, a well run low. War-mages strip fields and herds to feed a siege-working, and the hunger that follows a war is theirs as much as the soldiers'.

Material and Ritual Cost

Some workings rely on:

• prepared tools,
• inscribed media,
• offerings,
• focus objects,
• catalyst substances,
• or costly lasting works.

These are costs even when the caster's body is not heavily taxed.

A wizard with no chalk, no anchor, and no charged mirror may know the ritual perfectly and still be unable to cast it.

Side Effects During Casting

Even a successful spell may produce immediate side effects such as:

• numbness,
• bleeding,
• burns,
• frostbite,
• disorientation,
• involuntary emotional spill,
• temporary blindness or deafness,
• nausea,
• memory fragmentation,
• or convulsive aftershock.

No one who has seen a war-mage after a battle, bleeding from the ears and unable to say their own name, mistakes magic for a free show.

Long-Term Side Effects

Repeated casting may alter the caster over time.

Possible long-term effects include:

• chronic exhaustion,
• tremor,
• scarred channels,
• sensory damage,
• infertility,
• sleep disruption,
• emotional flattening,
• warped affinity,
• dependency on ritual aid,
• and shortened lifespan.

Each school leaves its own marks (see below), and the old mage's hands, eyes, and broken sleep tell a sharp-eyed village what was practised in the tower on the hill.

Permanent Casting Harm

Not all casting damage is reversible. Permanent harm occurs when repeated strain exceeds the body's repair capacity or when a single extreme event scars core channels.

Permanent outcomes most often include:

• channel scarring that permanently raises loss rates,
• irreversible sensory damage,
• chronic arrhythmia or tremor,
• persistent affinity warping,
• fertility loss,
• and reduced maximum throughput.

Healers and teachers of the craft sort permanent harm into three severity classes:

• Class I (Residual): lasting impairment that allows continued limited practice,
• Class II (Disabling): major reduction in safe casting capacity,
• Class III (Terminal): progressive collapse where further casting risks immediate death.

Class boundaries follow what the caster can still safely do, not how they look. Many a burnt-out war-mage at Class II lives on as a sellsword company's charm-maker or a lord's tutor, and a Class III mage who casts once more is the stuff of last stands in the songs.

Can Side Effects Be Healed Cleanly?

Many side effects can be treated, but clean restoration is not guaranteed.

As a general rule:

• acute overload effects are often recoverable with rest and compatible intervention,
• repeated micro-damage can usually be improved but not fully erased,
• structural channel scars are often manageable rather than curable,
• severe injuries that touch identity or the thread of the self require stabilization before restoration is attempted.

Clean healing is most likely when treatment is early, method-compatible, and performed before secondary damage cascades begin.

Some interventions trade one cost for another. For example, aggressive restoration may recover throughput while narrowing tolerance or increasing future backlash risk. Restoration forced repeatedly on the same injury can also tip into Failed Mending, in which repair overcorrects and the harm is preserved in altered form.

Healers therefore distinguish:

• clean recovery: capacity returns without meaningful long-term penalty,
• compensated recovery: capacity returns, but needs lasting care,
• palliative recovery: symptoms are reduced, but capacity remains permanently lowered.

Diagnostics for Magical Overuse

Overuse can be seen, not only guessed at.

Those who know how to read a caster look for four signs:

• throughput drift: more input needed for the same output,
• recovery lag: prolonged exhaustion and delayed stabilization,
• control variance: increasing instability in otherwise familiar forms,
• symptom persistence: side effects that fail to clear between cycles.

The usual tests are:

• a test-casting under a master's eye,
• comparing how the caster's channels answer now with how they answered in health,
• watching how long recovery takes after each working,
• and checks for contamination after dangerous work.

The risk bands are:

• Green: ordinary strain,
• Amber: early overuse signs; reduced load advised,
• Red: high collapse risk; casting suspension recommended,
• Black: critical instability; emergency-only intervention.

Who Forbids Dangerous Overcasting

Because overcasting can maim bystanders and bring down walls, whoever holds a place tends to forbid it there, and makes the forbidding stick with whatever force they have. Few places have rules beyond a few plain ones, and they are rarely written down:

• a caster may work great magic only with the leave of the lord, the temple, or the elders,
• a caster who has burned out once must rest before casting again,
• a master answers for an apprentice's backlash,
• whoever damages a hall, a field, or a well with a failed working pays for it, in coin, in service, or in blood,
• and a caster in Red or Black may be stopped by force, if anyone nearby is strong enough to try.

Who watches depends on who holds the caster:

• a lord watches the casters in his hall and his war-band,
• captains watch their own on campaign,
• temples and orders watch their priests and sworn casters,
• masters of a craft watch their journeymen in the forge, the quarry, and the building-yard.

What moves them is usually fear for their own walls and people, not the caster's soul. A sellsword company under siege lets its war-mage go into Red, and sometimes Black, because the alternative is the wall coming down; the companies that survive such nights tell of it ever after, and those that do not are remembered by the scorch on the stones.

School-Specific Side Effect Patterns

Examples of each school's marks:

• Crucible Magic: burns, fever, heat damage, scarred nerves
• Storm: arrhythmia, shaking, hair and skin charge injury
• Frost: tissue cracking, numbness, cold-damage, slowed circulation
• Dominion: empathy damage, intrusive thoughts, fractured identity boundaries
• Dream: sleep corruption, symbolic bleed, blurred reality-perception
• Necromancy: death-fascination, smell and touch desensitization, remnant contamination
• Sacrificial Magic: escalating tolerance to pain, moral corrosion, bodily depletion
• Sanctified Magic: devotional burnout, vow-scarring, collapse after miracle overreach

These are tendencies, not absolutes, but common folk know them well: the storm-mage's bristling hair, the necromancer who can no longer smell the dead, the dream-worker who wakes not knowing the room.

Canonical Failure-Mode Matrix

Where failures are written down at all, by temples, craft masters, lords' scribes, and the captains of war-bands, the more learned use a two-layer matrix, so that one house's account can be read by another.

The order of work:

• identify the method channel failure,
• identify the school-specific failure signature,
• assign a severity band,
• and act on the containment priorities for that band.

Method Failure Channels

Severity Bands

School-Specific Failure Signatures

Incident Logging Standard

Where a failure is written down, the account names:

• method channel failure,
• school signature,
• severity band,
• containment actions taken.

Few outside the learned houses keep such accounts. Most failures are remembered as a burned barn, a dead apprentice, or a story told at the hearth: the conjurer whose servitor came back with too many arms, the mill where a half-said binding still turns the wheel backwards, the crypt nobody enters since the old necromancer lost his grip on the dead.

Failure and Backlash

When casting fails, cost often rises sharply.

Typical failure modes include:

• uncontrolled discharge,
• wrong target or wrong conversion,
• rebound into the caster,
• structural collapse of the spell,
• accidental site damage,
• or contamination by the very force the caster tried to move.

Backlash is often worse than the intended cost because the spell loses its guided path. Failure can also leave something behind: a bad conjuring brings out the Ill-Called, malformed and hungry, and a necromancer's broken command can wake hostile remnants in the dead it held. Lords and temples keep a conjurer who knows how to send such things back, and beast-hunters take a bounty for whatever slipped away.

Divine Cost

Divine casting can reduce personal cost if the external source carries much of the energy burden.

However, divine magic may still impose:

• bodily overchannel,
• emotional overwhelm,
• sacred obligation,
• vow debt,
• or collapse after the miracle ends.

Safer does not mean free.

Social Cost

Not all costs are physical.

Some spells create:

• a lord's anger or a blood-price owed,
• ritual debt,
• suspicion and fear among neighbours,
• reputational stain,
• or obligations to temples, patrons, or kin.

This matters especially for blood magic, sacrificial rites, necromancy, and divine miracles. It is the cost that sends a hedge-mage down the road at night with torches behind, and the one that makes a miracle-worker the prize every warlord in the valley wants to own.
