How Magic functions
If you are familiar with the world of Fate/Stay Night and how the magic works in that world, then a lot of this will already be quite familiar to you.
In the world of this campaign, magic is quite limited in comparison to a normal D&D world. As such, in this world techniques have been developed in order to tap into the powers of Magic, and the higher orders thereof.
Magic is essentially defined as the usage of Prana from the natural world by using the Odic forces present in the host as a catalyst. Since the density of Prana is low in the world, one needs to use their Odic forces in order to,
- Concentrate the local Prana on a single point
- Purify the Prana of unwanted elements (if one wishes to cast something with fire, water is not needed)
- Shape the Prana into the desired state (Imma chargin mah fireball!)
- Release (BLARGH!)
However, the host (a living being) only has so much Odic force to spend before they weakened to a state where they are incapacitated, most of the time a user simply uses enough to become exhausted.
Odic Forces: Created by living beings, it also tends to leak out and become the Prana that saturates the air. Essentially the Odic Force that permeates a living being is highly refined Prana that helps the body to function.
Prana: Created by living forces naturally, though those of higher sentience tend to keep it internal thus creating their own Odic Force, whereas the excess permeates the enviroment to be called upon when sufficient Odic force is concentrated into a single point.
Given the limitation of the Odic force to any single being, a variety of methods have sprung up in order to deal with the limited supply.
Gem Casting: This is by far, one of the more simpler non-lethal methods for extending the supply of Odic Forces. Unfortunately, it is also one of the most expensive. The reason being is that Gem casting, as the name implies, requires the use of gems in order to work. The method behind it came from the discovery that gems can store Odic Forces without it leaking out or simply reverting into Prana. As such, since a host can only store so much of their own Odic Force within their body, it has become popular to simply store it within a jewel to be used at a different time. The downside of this method is that the user is drained for a small period of time before their body naturally restores the internal forces. However, this allows for greater quantity of casting to be availiable when the host decides to use the stored Odic force. Furthermore, it allows the user to store enough Odic force in able to cast higher level spells that normally s/he wouldn’t have been able to with just their natural limit of Odic Force.
Qualities that effect the storage of Odic force rests upon type of gem, size of the gem, quality of the gem.
Type of Gem: Amber/Amethyst (Poor) – Ruby/Emerald (Decent) – White Sapphire/Diamond (Superb)
Size: Small (For a ring) – Medium (Amulet size gem) – Large (Size of the average Human Fist)
Quality: Rough (Right out of the ground) – Shaped – Polished (Fine quality for the gem)
So, a Polished, large Diamond would have superior storage qualities over that of a rough piece of amber attached to a ring for example.
Sacrifice: A less popular method, even before the meddling of the church, which would use living beings as tools to released huge amounts of Odic Forces in order to tap into a larger amount of Prana. Of course, this is the more reliable of the ‘sacrificial’ methods, since you can call upon a time and a place to do this. Other variants involve the use of a active battlefield, a plague ridden town and essentially any area that deals with the end of a living being.
Prana: Of course, another way of dealing with the shortage of the Odic force, is simply to find an area that is more densely surrounded by Prana, which would allow the employment of less Odic Force for the same amount of Prana as compared to an area less saturated. Such areas usually involve the abundance of life force such as forests and less appealing, marshes and bogs. As such, Druids and elves who tend to favour such enviroments tend to do well there, but unfortunately tend to be less useful when moved to a lesser enviroment.
Magic circuits: In comparison, one can also just increase the efficiency of his//her own body when tapping into the Odic Force. Similar to how one can improve the storage qualities of a gem by simply shaping and polishing it, one can improve the flow of the Odic force by creating specific ‘paths’ for which it can flow. This however creates considerable strain upon the body, and most wizards can barely manage to create 2 in the entirely of their lifetime, an Elf can barely manage 3 if practicing similar methods. As such, these circuits are geneally passed down by inheritance through a bloodline, which allows for a much easier transferance as compared to an outsider, although it is possible. Unfortunately, there is a limit on how many a body can hold at any given time, which varies from host to host.
Although the transferance is still quite taxing on a host, it still allows however for improvement. Such as, even by transferring the 2 circuits that the current owner has to his successor, the successor still has the possibility of creating an addition circuit without destroying their body.
This method is usually used in conjunction with other methods listed above, and tends to favour the older bloodlines that favour this method as well as having luck to having a body capable of possessing a substantial amount of circuits.
Acularius: Should be sufficient (although with many errors most likely) to describe how magic works in this world.
