Sangromancy

Sangromancy

In the shadowy recesses of magical study lies the forbidden art of Sangromancy, or Blood Magic as it is more commonly known. Unlike the structured and refined traditions of Arcane, Nature, or Divine magic, Sangromancy is raw and untamed. It is a desperate act of willpower, forcing magic to manifest when all other resources have been depleted. This practice tears through the caster's very life essence, wreaking havoc on their body as blood vessels rupture, skin cracks, and vitality ebbs away. Magic practitioners are often warned of the perilous consequences of overexertion. The ability to cast magic is akin to a muscle—strengthened through practice but dangerous when pushed beyond its limits. Those who disregard these warnings, driven by hubris or desperation, risk their very lives as their life force is consumed to fuel their spells. This method, often branded as a form of Dark Magic, twists and warps the caster’s essence, making Sangromancy feared and mistrusted.
Sangromancy’s dark reputation stems from its cost. It transcends traditional classifications of Arcane, Nature, or Divine magic, as it draws directly from the caster’s life force rather than an external source. Many would-be wizards have perished, consumed by their own overreaching desire for power.
Yet, Sangromancy is not inherently evil. Its power lies in its potential for sacrifice, allowing spellcasters to push past their mortal limits to achieve the impossible. Desperation and determination intertwine, turning a dying spellcaster into a saviour at the cost of their own wellbeing.

What Sangromancy Offers

Sangromancy introduces a new and visceral way to interact with magic. It allows spellcasters to push beyond their limits, casting spells even when their resources have been exhausted, at the cost of their own vitality. This system offers:

• High Risk, High Reward: Tap into your life force to cast spells when spell slots are depleted.
• Tactical Decisions: Weigh the cost of your own health to determine whether a spell is worth the sacrifice.
• Narrative Depth: Add a layer of tension and drama to spellcasting, as each use of Sangromancy brings the caster closer to their limits—and possibly their demise.

Sangromancy is not for the faint of heart. It is a tool of desperation, a dangerous choice that carries great power at great cost.

Rules of Sangromancy

Casting with Sangromancy
A creature can cast a spell they know using Sangromancy if they do not have a spell slot of the required level or higher. When casting a spell this way:

• The caster must expend a number of Hit Dice equal to the level of the spell they wish to cast.
• The largest available Hit Dice in the caster’s unexpended pool must be used first. For example, if a multiclass character has d10 and d6 Hit Dice, they must expend the d10 first.
• The caster takes damage equal to the maximum value of each expended Hit Die, plus 1d4 per level of the spell. This damage cannot be reduced or mitigated.
• If the spell is a healing spell, the caster takes additional damage equal to the total healing dealt by the spell.

Spell Slot Expulsion
If a caster has spell slots of a lower level than the spell they are attempting to cast with Sangromancy, all lower-level spell slots are immediately expended when the spell is cast.
Overextension Consequences

If the damage taken from Sangromancy reduces the caster to 0 hit points:

• The caster automatically fails one death saving throw for every 10 points of damage that exceed their remaining hit points.
• If using the Doomed & Dying rules from Jacob’s Opus of Lunacy (JOL), the caster fails one death saving throw for each Hit Die expended in the casting if they are at 0 hit points or they have the Dying condition.

Restrictions on Use

• Sangromancy cannot be used if the caster has the required spell slot or higher available.
• Attempting to cast a spell using Sangromancy while under the Dying condition automatically fails the death saving throws described above.

Jacobs Musings
Ones ability to manipulate and channel the weave, like a muscle, this ability can be stretched and strained. But there are limits to every mortal’s endurance, and to push beyond them is to court disaster. My first mentor once told me, “Even the strongest steel will snap if bent too far, Jacob. Learn your limits, or magic will teach them to you.” It was advice I failed to heed in my youth.

The first time I overreached my abilities, it felt as if my own body was being torn apart. I remember the searing pain, like shards of glass ripping through my veins, as I tried to force a spell into existence when my own energies were utterly spent. My skin cracked, blood vessels burst, and my entire being felt like it was unraveling. The spell succeeded, but the aftermath was a lesson written in agony. Never again.

This is the nature of Sangromancy—magic pulled from one’s very essence, a raw and brutal act of desperation. Some call it part of Dark Magic, and I suppose that label is fitting. It is of neither Arcane nor Divine, or Nature. It is our life essence itself, twisted into something unnatural, leaving scars both seen and unseen.

And yet, there is something undeniably fascinating about it. Sangromancy is a stark reminder that life itself is a form of magic, one of the most powerful and mysterious kinds. The fact that a spellcaster can use their life force to manifest magic proves this truth. Is it not humbling, even beautiful in a strange way, to know that our existence is so deeply intertwined with the Weave?

But beauty and power do not excuse the cost. To embrace Sangromancy is to gamble with one’s own vitality, to turn life’s magic into a fleeting, desperate force. I have seen those who wield it recklessly—desperate wizards in battle, or arrogant novices overconfident in their abilities. Too often, they fall victim to their own hubris, their lives snuffed out like a candle burned at both ends.

I do not judge those who resort to such measures. Desperation has its own kind of wisdom, and sometimes the cost is worth the result. But for me, the memory of that pain, of feeling my life unravel with that forced spell, is warning enough. Magic may be a tool, a science, or an art, but it is also a reflection of our fragility. Perhaps that is why I find Sangromancy so haunting—it is a reminder that even the strongest among us can only bend so far before we break.

And yet, to think that our very essence can fuel the Weave… it is humbling, even inspiring. Perhaps, in a strange way, Sangromancy is not just a testament to magic’s power but to life’s resilience as well. Still, I will not willingly tread that path again. Life may be magic, but it is also precious, and I see no reason to squander what little remains of mine.
