 The ability of mere paper to store such potentially vast amounts of energy, even single use, has led to the restriction of import on paper in certain totalitarian nations in order to prevent the creation of [[Scroll Bomb|magic bombs]], which are often used by insurrectionary elements in these nations as a tool of revolution via guerilla warfare.
-In general, scroll media which is less heavily impacted by degradation upon use will cost more potentia to imbue. There is a correlation between reuse potential and imbuing cost of a scroll media. The more times a scroll can self-refill from leylines, the more difficult it is to imbue it in the first place. This relationship is not wholly linear, however, as certain types of media (namely, [[gold]]) can refill nearly indefinitely, yet imbuing golden scroll media does not have an infinite cost.
 ==== Scroll Media ====
-These numbers are not absolute, but they are general guidelines for the efficacy of different media in scroll creation. The multiplier describes the amount of potentia required to imbue a scroll as opposed to casting the spell immediately. The potentia limit describes how powerful the spell contained in such a scroll may be. The expected uses describes how many times the same scroll is expected to refill itself given adequate leyline coverage (not counting the initial use).

+In theory, any material can be used as a spell scroll medium, but these are the only materials common enough to be noteworthy.
 Of these materials, paper is especially notable for its extremely high potentia limit per gram relative to its abundance and ease of imbuing. As it has a nearly perfect 1:1 ratio compared to casting the spell manually, as well as a respectable refill rate, it is almost always more efficient to imbue a spell scroll rather than waiting for the right moment to cast the spell, considering in many cases, this allows you to gain an extra cast "for free" if in an area with good leyline coverage.
-Iron is useful for storing vast amounts of energy in a durable form, and is common as a "magic battery" of sorts for vehicles which run on magic. However, of the metals, it corrodes very quickly, and is not useful for spellbooks.

 Plastic is notable for its extremely high potential reuse count compared with its low imbuing cost, but it is scorned among serious mages for its low potentia limit and unreliability.
+=== Precious Metals ===
+Owing to its excellent conductivity, and very high potentia storage capacity, if the creator of the spell is interrupted or distracted while imbuing the scroll, then the scroll's stored magical energy will disperse immediately, forcing the creator to start over from nothing. Maintaining focus for long enough to create such a thing requires going without food and water for potentially many days, which is an experience not unlike that demanded by the [[open mana ritual]]. This drawback is present for copper, silver, platinum, and gold spell media.
 Copper is considered the lowest grade of material from which a usable [[spellbook]] may be made, and its use is common among magic students who cannot afford finer metals.

 Silver is the material favored by most mages for the creation of their personal spellbook, as a mage very rarely needs to cast the same spell more than 1,000 times in their lifetime.
-Platinum is rarely used for spellbooks due to its rarity and relatively high imbuing cost, but it is slightly easier to come by than pure gold, has a higher tolerance for impurities and scratches, and much easier to imbue, so it isn't unheard of for a spellbook to primarily use platinum. Scrolls made of platinum are considered to be functionally permanent, although it is known to mages that they are not truly permanent in much the same way that one knows a knife cannot be re-sharpened forever.

+This is the highest-grade scroll media which is in widespread use among sapes. Due to the very high refill rate, and the fact that the energy limit of a spell scroll is tied to the mass of the scroll, platinum scrolls may be made using a thicker sheet to enable them to store a more powerful spell. Certain platinum scrolls are kept in the armories of nations, for use as weapons of war. Imbuing such a spell into a platinum medium, considering the multiplier of roughly 250, and the extremely high energy limit, is entirely beyond the capability of any individual.
+=== Golden Scrolls ===
+Pure gold is the ultimate material for spell scrolls, but it must be absolutely pure gold with no impurities, scratches, or imperfections of any kind. The presence of any impurities or imperfections increases the imbuing cost and re-introduces the potentia limit and reuse limit of lesser grades of material to be similar to the lowest grade material present in it. 18 karat gold sheets are often passed off as gold by unsavory merchants, resulting in efficacy similar to silver or even copper depending on which metals are present in the alloy. However, this is much worse than simply using pure silver or copper, as the user will experience the drawbacks of imbuing gold (extremely high potentia cost) with none of the benefits.
-==== Golden Scrolls ====
+With almost zero exceptions, gold spell scrolls are imbued by dragons or fae folk, who have far more potentia to draw upon, and far more time to spend, than sapes do. Such scrolls have on rare occasion been created in collaboration with sape mages who have rendered extraordinary services to a dragon or fae. There should in theory be a limit

The presence of any impurities or imperfections increases the imbuing cost and re-introduces the potentia limit and reuse limit of lesser grades of material to be similar to the lowest grade material present in it. 18 karat gold sheets are often passed off as gold by unsavory merchants, resulting in efficacy similar to silver or even copper depending on which metals are present in the alloy.

+The most common use of gold spell scrolls is for ceremonial use by institutions like churches, or to continually project magical barriers around a city. There have been only very few truly pure gold spellbooks, almost all of which were in the possession of [[speaker|speakers]] from [[Feyndraig]] who had the longevity for the high imbuing cost of pure gold to be worthwhile. Once a pure gold sheet has been fully imbued with a spell, it gains some regenerative properties, will resist most damage, and will self-heal its own scratches.

-Gold is also the most difficult material to imbue. Owing to its excellent conductivity, if the creator of the spell is interrupted or distracted while imbuing the scroll, then the scroll's stored magical energy will disperse immediately, forcing the creator to start over from nothing. This is, ultimately, the reason why so few gold spell scrolls exist. Maintaining focus for long enough to create such a thing requires going without food and water for potentially many days, which is an experience not unlike that demanded by the [[open mana ritual]].
+Large gemstones may be used to carry many different spells, but are more useful as carriers of enchantments than they are as scrolls (due to manaflow degradation).
