The importance of light can often be underestimated. A Lumenmancer is capable of warping this resource and even the symbolism to their desire in ways to rival a Pyromancer. Lumenmancy can be equally inspiring or terrifying depending on the Caster.

A Caster projects a small portion of their own bonded Rigen into the atmosphere in a way that will attract and harness the ambient unbonded rigen. The Personal Rigen acts as the catalyst that generates the change to initiate the intended spell. And while experienced practitioners are able to perform spells more often, it does take a toll on the unbonded rigen that they are harnessing. While the ambient supply is technically limitless the more that is used in a short period of time the more hazardous a spell becomes to everyone, including the Caster.

The amount of time it takes to produce a Lumenmancy spell safely will vary. What is the most influential factor is how much light is being manipulated or created. When there is more it takes longer for the spell to form. However, that is to produce a spell where the unbonded rigen remains stable. Large, powerful spells can be made at nearly instantaneous speeds, but even being in their proximity can severely harm the Caster and the environment. Masters are no more exempt from this than an apprentice. The main difference is that masters can cast beginner spells very quickly and in a stable fashion, while an apprentice could require several minutes to generate the same effect with the same level of stability. Regardless of the Caster’s capability, the longer they spend to cast a spell the more stable, controllable, and safer it will be.

At first the Caster learns how to generate light before they know enough to manipulate a natural light. This Rigen infused light can vary in appearance, depending on the individual Caster and their skill, but typically is more golden or silver regarding its radiance. Rigen infused light is generally brighter than torchlight and even daylight at the higher levels.

Prerequisites

Due to the spell being fueled by Harnessed Rigen more than Personal Rigen, it usually takes someone with a little more understanding of bonded vs. unbonded rigen. Before a Caster can gain any skill in Lumenmancy they must be at least a Journeyman in Rigenology.

Initial Learning

Lumenmancy cannot be self-taught, even by someone that has learned Aeromancy, Geomancy, Hydromancy, Pyromancy, and/or Umbramancy. The conversion process of Rigen is different between each element and requires an instructor that is at least an Expert with the spell.

Skill Levels

---

Apprentice

With the help of an instructor, the Caster learns the Conversion process for Lumenmancy specifically. A Caster has not perfected their technique on converting unbonded rigen into light. They are not able to manipulate natural light, and have limited control over the light they create. They can generate a small floating sphere of a size equal to a candle flame which comfortably illuminates a ten-foot radius. Their control is limited to about ten feet away.

---

Journeyman

Now the Caster has a better understanding of the conversion process and can create greater quantities of light than before. They also possess better control of their spell. A Journeyman could form a single sphere of light to comfortably illuminate a five hundred square foot room. Alternatively, the Caster can concentrate the light to a single ray that could temporarily blind someone for a couple minutes. At this point, they can begin to experiment with generating their light in an array of colors at the moment of casting. They are not able to change the color of a spell that has already been cast. Their control extends to about twenty-five feet away.

---

Expert

A Caster now begins to learn how to manipulate natural light by infusing it with Rigen. This allows for control over significantly greater quantities of light since less Rigen is consumed by the infusion process. A Lumenmancer is now able to create light that is solid or liquid. The shape of the solid must be determined at the beginning of the spell, whereas the liquid’s shape can be altered at any point during the spell. Also, within their capability is the knowledge to instantly put out natural light. At this stage, they can also change the color of a light spell after it has been cast. Their control extends to about fifty feet away.

---

Master

With their exceptional knowledge and experience, a Master becomes capable of controlling terrifying amounts of light. They also learn how to focus a ray of light to a point where it can sear and burn anything it shines on. Even solid light that they have created can be reformed at their desire at any point. The range that the light shines, regardless of intensity, is now subject to the Caster’s desire as well. A Master learns how to put out Rigen infused light. With practice, they can unravel another Lumenmancer’s spell. Their control extends to a couple hundred feet away.

---

Cost

The Caster must provide the initial Rigen to form the spell. Each use of Lumenmancy requires 10 points of the Caster’s Spellpool. Each use also takes 50 points from the Atmopool. When the Caster is utilizing the spell to a degree lower than what their fully capable (Example: A Journeyman using the spell to the same extent that an Apprentice could perform), the personal cost is halved to 5 points and the Atmopool cost is halved to 25 points. The personal cost is halved only once, but the Atmopool cost continues to be halved each time a new tier of capability is achieved, Review the following table for quick reference to Rigen costs.

	Caster Ability	Apprentice	Journeyman	Expert	Master
Spell Level	Personal/Atmo
Apprentice		10/50	5/25	2/13	5/7
Journeyman			10/50	5/25	5/13
Expert				10/50	5/25
Master					10/50

Risks

Unbonded rigen is quite hazardous when it is not completely stable. Even when there is a plentiful supply of stable Rigen, a Caster that does not generate the spell properly will suffer first degree burns to any exposed flesh or possibly singe the surface of nearby objects. When the Atmopool gets low the unbonded rigen from neighboring areas flows in to refresh the supply. However, it requires a few days for that Rigen to stabilize. If it is used before stabilizing it poses great risk to the Caster and the environment. Any exposed flesh in close proximity to the source of the spell fueled with unstable Rigen suffers from second degree burns. The spell itself becomes volatile and unravels in a burst of energy once the source makes physical contact with any surface.
