Blood Magic

Blood magic appears to consist primarily of personal-only buffs (see Spells , below), but a skilled user can also use it to heal themselves or others, or to burn out infections via blood transfusion. At the upper levels blood mages can sustain themselves solely on blood, compress impossible amounts of blood under extreme pressure into their bodies, draw power from blood to boost their ability to use blood magic, and utilize blood that isn't their own.

Blood magic is taught at the Athenaeum of Quills and Blood, and blood mages can be employed as healers or combat mages. Multimages with access to blood magic can extend the range of their touch spells by getting a target to touch their blood, as the caster's blood counts as them for the purpose of using magic.

## Spells

### Aarde's Touch

*Channels the warmth of your blood to create a small fire at your fingertips, which does not burn you. Objects set on fire or heated may still harm you. Saps heat from your body and may leave you feeling chilly if used too long. Consumes 0 drops of blood.*
—*Worth the Candle* Chapter 9: "Making Magic"

Aarde's touch is the first blood magic spell that Amaryllis teaches Juniper. It uses the caster's body heat to power a flame, which can be used for light or to burn things.

### Bare Augmentation

Blood magic spells that directly increase physical power are called bare augmentation. There are several spells in this group, all of which provide a short burst of strength (without increasing resilience) for the price of a few drops of blood.

#### Crimson Fist

*Channels the force of your blood to gain kinetic energy in the form of a punch. Your fist is in no way protected by this spell. Drawing on this spell too often may leave you feeling sluggish. Consumes 3 drops of blood.*
—*Worth the Candle* Chapter 9: "Making Magic"

Despite the name, Crimson Fist can do more than augment punches. It appears to be able to augment almost any arm movement. Juniper, in particular, appears to use it with sword blows.

#### Crimson Foot

*Channels the force of your blood to gain kinetic energy in the form of a kick. Your foot is in no way protected by this spell. Drawing on this spell too often may leave you feeling sluggish. Consumes 3 drops of blood.*
—*Worth the Candle* Chapter 15: "Whys and Wherefores"

Crimson Foot, like the rest of the bare augmentation spells, can presumably do more than enhance kicks. However, the distinction between places where Crimson Foot or Sanguine Surge are applicable is somewhat unclear, as both work with leg muscles.

#### Sanguine Surge

*Channels the force of your blood to gain kinetic energy in the form of a leap. Your body is in no way protected by this spell. Drawing on this spell too often may leave you feeling sluggish. Consumes 5 drops of blood.*
—*Worth the Candle* Chapter 15: "Whys and Wherefores"

Like Crimson Fist, Sanguine surge is more broadly applicable than the description seems to imply. For example, Juniper uses it to run faster.

### Transfusion Spells

Blood magic revolves around manipulating *the caster's* vital essence. How, then, can they use it to influence other people? The answer is apparently transfusions.

While Bloodline is the only spell in this category that Juniper uses, it is theoretically possible to apply the Aarde's Touch or Bare Augmentation spells via transfusion, as well as to create more exotic effects like burning out nascent infections.

#### Bloodline

*When you have forced your blood into another person, you can use it to heal or harm them. Apply a bonus or malus of up to your POW/SPD/END to them, at the cost of your own, with five factor modifiers.*
—*Worth the Candle* Chapter 51: "Blood in the Water"

Bloodline is the spell that blood mages use to heal other people. The healing presumably functions in a manner similar to bone magic's healing, with a temporary boost in END resulting in more lasting healing.

The five factors mentioned in the description are all binary, and are Aerb's equivalent of blood types. Unlike Earthly blood types, the five factors are almost entirely determined by species. Transfusions appear to have non-fatal side-effects as long as at least three of the five factors match.

An interesting note is that Aerb has more sapient species than there are possible 5-factor alignments, meaning there are different species that can reliably serve as a perfect match to each other.

### Blood Control

Blood mages gain a limited amount of telekinetic control over their own blood, which is the basic skill behind their ability to create blood objects. In addition to the spells listed here, a blood mage with enough skill can control the flow of their blood to stop their injuries from bleeding, or to stop themselves from blushing.

#### Blood Hardening

*Channels the force of your blood to minimize damage from attacks. Bludgeoning attacks are reduced by three orders of magnitude. Piercing and slashing attacks are reduced by one order of magnitude. Only applies to parts of your body that have sufficient blood flow. Consumes 5 drops of blood.*
—*Worth the Candle* Chapter 152: "The Time to Talk"

Blood Hardening, despite the name, appears to operate by using telekinesis to apply a counter force rather than actually hardening the mage's blood. Between this spell, the ability to stop themselves from bleeding, and the ability to heal themselves blood mages are actually reasonably durable.

#### Claret Spear

*Channels the force of your blood into a pointed weapon. Damage and attack are dependent upon your Blood Magic level. Blood cost is dependent upon blood loss and your roll on the blood recovery chart. Complex variant shapes require higher Blood Magic.*
—*Worth the Candle* Chapter 152: "The Time to Talk"

The most common blood weapon is a spear.

The spell is difficult to use, requiring concentration to maintain the form. It's also hard to use because it doesn't really obey the laws of physics like normal, resulting in somewhat counterintuitive movement.

There are also difficulties associated with pulling a large quantity of blood from the mage's body. In addition to the obvious symptoms of blood loss while the spear is active, if the mage wants to return the blood to their body it needs to be purified as it's potentially been exposed to infections or toxins that they don't want inside of them.

On the other hand, the claret spear is good because of its interactions with other spells and magics. Stabbing someone with the spear allows the mage to force blood into their opponent, which counts as an infusion for the purposes of Bloodline. Considerations for multimages with regards to touch spells presumably also apply.[*speculation*] Finally, the Claret Spear can be thrown as long as the mage is willing to eat the blood loss, which can combine well with the above.

## Blood Magic in the Game Layer

Blood magic's primary stat is WIS, and its secondary stat is probably END

Known virtues include:

* **Hypertension** (level 20): doubles Juniper's blood volume
* **Flow Control** (level 40):  Allows control of all your blood as long as it's in contact with you.[*citation needed*]

Blood magic is affected by two of Essentialism's virtues- **Soul Saturation** allows Juniper to use blood in place of ink (for ink magic) and infusions (for pustule magic), while **Soul Symbiote** doubles his effective skill in Blood Magic, up to a cap of 75.

## Known Practitioners

* Amaryllis Penndraig studied blood magic at the Athenaeum of Quills and Blood.
* Juniper Smith is an unlicensed blood mage
* Lisianthus Penndraig is a combat blood mage
* Several strains of Doris Finch are blood mages of varying skill.

"The blood in your body provides nutrients and oxygen, it clots your wounds, and it provides the basis for a whole host of other healing when you’re injured.

Note that at this point juniper only knows aarde's touch, crimson fist/foot, and sanguine surge. Aarde's touch obviously isn't bare augmentation, so at least one of the other three is. Since they're so similar, it seems likely that they all are. We also know that the Claret spear \**isn't\** bare augmentation from Lisi's reponse earlier in the chapter.

23. ↑ “There are four difficult aspects to the technique,” said Lisi. “The first is operating while light on blood, though there are techniques to increase the blood volume of the body and magically compress blood to have a greater natural store. The second is that concentration must be maintained on the Claret Spear at all times, even in the heat of combat. The third is that the spear must be retracted back into the body, unless you want to spend an enormous quantity of blood with every use, and the blood outside the body will have contact with foreign particulates, air, and germs, which means techniques have to first be mastered to purify blood, either inside the body or outside it. Fourth, you have to come to the counter-intuitive understanding that the spear is maintained in its shape by pure will, and does not obey the laws of physics as such.”

I had already learned that aspect, back when I had given Fenn a quick and sloppy transfusion, this was just a fast, easy, and effective way to do it against an opponent. All I would need to do was stab them once, push my blood into them, and then use it against them.
