Certain tasks are to complicated to be covered solely by an Ability. To accomplish them, a character must master a body of knowledge before being able to use his skills effectively. In the Forgotten Suns campaign, such knowledge is represented by sciences. Sciences are traits that live outside of the normal attribute/ability system. They are rated in dots like other traits, however these dots do not provide dice pools or other "active" effects. Instead, sciences act as a passive limitation on certain tasks. That is, some tasks are not possible unless you have a certain number of dots in a related science.

Most sciences have steeper requirements than Abilities, usually requiring the character to know one or more Abilities at a certain level. In addition, sciences always require instruction of some kind, either from a tutor, book or other source. This requirement is often the limiting factor in learning sciences, particularly those dealing with First Age technology.

At low levels, sciences cost only slightly more than than abilities, but become much more costly as they progress. The first dot in a science costs 2xp (assuming all the requirements are met). Additional levels cost a number of xp equal to the xp paid for the previous two levels, plus one. Training time is 20 times the xp cost, in hours. These times assume the required instruction. So, the progression goes like this:

Science Cost Training time (hours)
2 40
●● 3 60
●●● 6 120
●●●● 10 200
●●●●● 17 340

These rules can be used in both First and Second Edition games; however, they will largely make reference to concepts from Second Edition books, particularly Wonders of the Lost Age and Oadenol's Codex, as the rules in these books are mostly edition agnostic. In First Edition, these rules replace the rules for Arts and Sciences in the Player's Guide. In Second Edition, they replace the rules for occult arts. Note that while standard Second Edition occult arts provided both extra dice and the ability to perform various procedures, under these rules, sciences only provide the latter. Under these rules, it is possible to learn normal specialties based on sciences. For example, a character might learn an Occult specialty in Enchantment. The combination of dots in science and specialties would be mechanically equivalent to standard Second Edition art, though it would be slightly cheaper. Sciences in these rules are also cheaper than sciences from First Edition.

When these rules list ability requirements, these should include the rating of applicable specialties in the total. Further, these rules are assumed to work with rules that treat the various crafts as specialties instead of complete skills. For example, something requiring Craft (Fire) 4 could be done by someone with two dots in Craft and a +2 Fire specialty.

Many sciences are practiced using specific rituals, formulas or procedures. These often have their own requirements, which must be met in addition to the requirements for the science itself.

Architectonics

Anyone who can channel essence can attune to a manse. Usually, those with skill can also figure out how to alter or repair a manse. With sufficient Craft, Lore and Occult skill, it is even possible to design a manse that will cap a demesne (core.246, ex2e.113). Without knowledge of the science of architectonics, however, the resulting manse does little else. Its designer will have no control over what kind of hearthstone is produced, and cannot give the structure any special abilities at all.

Architectonics allows a character to design manses using the point-based powers found in Oadenol's Codex. It also allows for the repair of manses with such powers, though 1- and 2-point powers can be repaired without it. Repairs and alteration of higher point powers is possible for those without the science, but the result is always substandard in some way (e.g. requires continual maintenance, leaks essence, etc.).

Science Requires Allows
Lore 3, Occult 3, Craft (Earth) 4, Geomancy ●● Design of manses containing 1-point powers, repair of up to 3-point powers
●● Lore 4, Occult 4, Craft (Earth) 5, Geomancy ●●● Design of manses containing 2-point powers, repair of up to 4-point powers
●●● Lore 5, Occult 5, Craft (Earth) 6, Geomancy ●●● Design of manses containing 3-point powers, repair of up to 5-point powers
●●●● Lore 6, Occult 6, Craft (Earth) 7, Geomancy ●●● Design of manses containing 4-point powers
●●●●● Lore 7, Occult 7, Craft (Earth) 8, Geomancy ●●● Design of manses containing 5-point powers

Charmcraft

As charms increase in power, it becomes more difficult for exalts to learn them without help. Exalts without tutors or other knowledge of a charm are, essentially, forced to "invent" the charms they learn. This is no problem with charms up to Essence 3. Beyond this, however, it requires detailed knowledge of charm magic, represented by the charmcraft science. Charmcraft can be used both to learn existing charms and to invent new ones. (Absent teachers, both actions are essentially identical.)

There are two exceptions to how charmcraft operates. The first is Martial Arts. Martial Arts charms are more universal and, therefore, not as in tune with a character's essence as her "native" charms would be. Consequently, Martial Arts charms of Essence 4 and higher add one to their effective essence level to determine which level of charmcraft is needed to learn them without a trainer.

The second exception is sidereal exalts. Sidereal magic is such that sidereals cannot invent entirely new charms, so they cannot use charmcraft to do so, though they can still use it to learn existing charms. On the other hand, sidereals are much more in tune with Martial Arts than other exalts, so do not suffer the previously mentioned adjustment to Martial Arts charms.

Unlike most sciences, charmcraft itself is most often learned through trial and error, so may be self-taught at twice the training time. Charmcraft is never needed for charms that are taught to the exalt by a teacher or some other source.

Science Requires Allows
Essence 4 Creation of charms requiring Essence 4.
●● Lore 1, Essence 5 Creation of charms requiring Essence 5.
●●● Lore 2, Occult 1, Essence 6 Creation of charms requiring Essence 6.
●●●● Lore 3, Occult 2, Essence 7 Creation of charms requiring Essence 7.
●●●●● Lore 4, Occult 3, Essence 8 Creation of charms requiring Essence 8.

Genesis

Described in Wonders of the Lost Age, this science works just like magictech does, but replacing Craft (Genesis). This science requires the Wood craft and cannot be higher than the lowest of the character's Lore, Medicine or Occult ratings.

Magitech

Described in Wonders of the Lost Age, knowing the science of magitech allows use of Craft skill on magical devices. Anywhere rules call for a Craft (Magictech) roll, use plain Craft ability (plus any magitech specialties) as the pool. The rating in this science acts as a limit: characters can only use the magitech science on artifacts, manses or devices with a rating equal to their magitech science rating or less. This science requires the Air and Fire crafts and cannot be higher than the character's Lore rating.

Necromantia

The science of necromantia works exactly as spellcraft, but for necromancy instead of sorcery.

Necrosurgery

Introduced in Abyssals and expanded in the Book of Bone and Ebony, necrosurgery is the science of assembling and animating dead flesh and harnessing necrotic energy. Anywhere rules called for Craft (Necrosurgery), use plain Craft ability (plus any necrosurgery specialties) as the pool. The rating in this science sets an upper limit on the size class (BoBE? 97) or artifact rating of an item created using this science. Necrosurgery does not require knowledge of a craft art, but its rating may not exceed the lowest of the character's Lore, Medicine or Occult ratings.

Perfection

This science deals with creating exceptional weapons and other creations and represents the dedicated knowledge of metallurgy, heat and other minutia that are need to forge exceptional weapons, armor and other items. It requires an art for creating such equipment (usually Fire). The first dot of this science allows objects to be made up to the level of "Exceptional" (Ex2 365). The second allows creation of "Perfect" items (Ex2 366). Generally learning this science beyond this is pointless. The magitech science may also be used for the creation of exceptional items, so this science is rare among exalts; however, the requirements for this science are less stringent, so mortals (and some exalts) may prefer this path.

Spellcraft

Under canon rules, all exalts can teach themselves most charms. Under this system, learning more powerful charms on your own requires detailed knowledge of charm magic, represented by the Charmcraft science. Rating in this science is compared to the minimum Essence requirement of charms (referred to here as ME). Characters can learn an existing charm without a tutor only if they have a Charmcraft rating equal to or greater than the charm's ME minus three. (This means that any exalt can teach themselves Essence 3 charms or lower without Charmcraft.) Characters with charmcraft can also invent brand new charms; however in this case, the science's rating is compared to ME minus two.

Science Requires Allows
Terrestrial circle sorcery Design of terrestrial circle spells
●● Celestial circle sorcery Design of celestial circle spells
●●● Solar circle sorcery Design of solar circle spells

Thaumaturgy

Alchemy

Alchemy combines a number of disciplines, such as pharmacy, metallurgy, even cooking, to combine and transform different ingredients. Alchemy requires specific formulas, recipes which usually must be followed very closely. Most formulas result in some type of material, usually a liquid, that provides useful effects when consumed. Other formulas focus only on transforming material from one type into another.

Anyone with an Occult rating can practice mortal alchemy. In fact, some very simple alchemical formulas can be prepared without any training in the science of alchemy at all. Anyone with at least one dot in Occult can use the rank 0 alchemical formulas from Oadenol's Codex.

Science Requires Allows
Occult 1, Lore 2, Craft (Water) 1,
instructions found in Salt
May use known rank 1 alchemical formulas and invent those of rank 0
●● Occult 3, Lore 4, Craft (Water) 2,
instructions found in Aether
May use known rank 2 alchemical formulas and invent those of rank 1
●●● Occult 5, Lore 4, Craft (Water) 3,
instructions found in Gold
May use known rank 3 alchemical formulas and invent those of rank 2
●●●● Occult 5, Lore 5, Craft (Water) 5,
instructions found in Gold
May invent alchemical formulas of rank 3

Astrology

While nowhere near the fate-altering ability of sidereal astrology, the astrological sciences allow mortals and exalts alike to read the stars for various information. As with the other thaumaturgical sciences, astrology makes use of specific procedures to find specific information. A small number of these rituals can be performed by anyone with Occult skill, but most require knowledge of the astrological science. Typically, an astrologer also needs instruments to read the stars and a collection of books of stellar lore.

Instruction in the first three levels of astrology is not hard to find, with both teachers and books available in most major cities.

Science Requires Allows
Occult 1, Lore 1 May use known rank 1 astrological procedures from Oadenol's Codex, and invent those of rank 0
●● Occult 3, Lore 2 May use known rank 2 astrological procedures from Oadenol's Codex, and invent those of rank 1
●●● Occult 5, Lore 3 May use known rank 3 astrological procedures from Oadenol's Codex, and invent those of rank 2
●●●● Occult 5, Lore 4 May invent alchemical procedures of rank 3

Demonology

Exalts most often use sorcery to summon and bind demons, but even mortals can do so with the right rituals, albeit with greater danger. Rituals also exist for more than just summoning demons, but also guarding against them, banishment and so on. Even true sorcerers often use such rituals as safeguards when summoning demons. Rituals used in demonology are found on in the Art of Demon Summoning section of Oadenol's Codex.

Science Requires Allows
Occult 1, Lore 1 May use known rank 1 rituals and invent those of rank 0
●● Occult 3, Lore 2 May use known rank 2 rituals and invent those of rank 1
●●● Occult 5, Lore 3 May use known rank 3 rituals and invent those of rank 2
●●●● Occult 5, Lore 4 May invent rituals of rank 3

Elementalism

Exalts most often use sorcery to summon and bind elementals, but even mortals can do so with the right rituals, albeit with less ability. Rituals also exist for other elemental-based effects, such as guarding against them, banishment and so on. Even true sorcerers often use such rituals as safeguards when summoning elementals. Rituals used in elementalism are found on in the Art of Elemental Summoning section of Oadenol's Codex.

Science Requires Allows
Occult 1, Lore 1 May use known rank 1 rituals and invent those of rank 0
●● Occult 3, Lore 2 May use known rank 2 rituals and invent those of rank 1
●●● Occult 5, Lore 3 May use known rank 3 rituals and invent those of rank 2
●●●● Occult 5, Lore 4 May invent rituals of rank 3

Enchantment

Enchantment 1 allows production of 1- or 2 dot enchantments. A rating of 2 in the science allows production of 3- or 4-dot enchantments and Enchantment 3 allows production of 5-dot enchantments and higher.

Science Requires Allows
Occult 1, Lore 1 May use known rank 1 rituals and invent those of rank 0
●● Occult 3, Lore 2 May use known rank 2 rituals and invent those of rank 1
●●● Occult 5, Lore 3 May use known rank 3 rituals and invent those of rank 2
●●●● Occult 5, Lore 4 May invent rituals of rank 3

Geomancy

Ratings in geomancy allow for the production of geomantic effects using the three possible levels in the science the same way the levels of Enchantment are used.

Orisonurgy

How mortals use prayer. Also include weather control.

Thanaturgy

How mortals deal with the dead.

Vivomancy

How mortals control animals, crops and other life.

Warding

Mortal rituals to keep various things away. Does not include the exorcism bits.

True Alchemy

While mortals dabble with trivial effects, more powerful creations can be made using true magic. Like sorcery, magical alchemy requires use of specific charms for each level. Higher levels of magical alchemy have been theorized, but never mastered.
