Astrologers have the following game statistics.
Abilities: Intelligence is the key ability for astrological magic. Astrologers gain bonus spell formulae per day based on their Intelligence. To attempt a spell formula, an astrologer must have an Intelligence equal to 10 + the spell’s level.
Hit Dice: d4.
The astrologer’s class skills (and the key abilities for each skill) are Alchemy (Int), Astrology (Int), Knowledge (all skills, taken individually) (Int), Concentration (Con), Craft (Int), Gather Information (Cha), Profession (Wis), Scry (Int), and Spellcraft (Int).
Skill points at 1st Level: (4 + Int modifier) x 4.
Skill points at Each Additional Level: 4 + Int modifier.
All of the following are class features of the astrologer.
Weapon and Armor Proficiency: Astrologers are skilled with the club, dagger, heavy crossbow, light crossbow, and quarterstaff. Astrologers are not proficient in any type of armor or shield. Arcane spell failure chances are incurred only when the astrologer attempts to prepare a spell formulae for a spell with a somatic component. Invoking (casting) a spell never results in an arcane spell failure chance.
Spells: Astrologers cast arcane spells by drawing on the energies radiating from the celestial realms. Because the physical heavens are in perpetual motion, these energies constantly change, giving astrologers great flexibility when working their magic. This same flexibility, on the other hand, requires astrologers to prepare unique spell formulae for each spell they attempt to cast.
Astrologer spellcasting has three basic elements: creating a spell formula, using an astrological fetish (if necessary), and invoking the spell. Each step is discussed in turn below:
Spell Formulae: Astrologers do not learn spells from books or from meditation. Instead, they use their knowledge of astrology to create spell formulae that take advantage of the present and future positions of the stars and planets. Astrologers can create a number of spell formulae per day based on class level (and bonus formulae based on Intelligence). Creating a spell formula requires intensive, tiring astrological computation. Once an astrologer has used up all her spell formulae slots for the day, she must get a good night’s rest before trying again.
An astrologer’s own nativity horoscope is an important part of every spell formula. Spell formulae, therefore, are only usable by the astrologer who computes them. Astrologers have been working on “universal spell formulae” for centuries, but so far the magic of astrology has proven far to delicate and personal to generalize.
The first step in creating a spell formula is to choose the desired spell. The astrologer can choose any spell on the astrologer spell list (within the astrologer’s level and Intelligence limits). Any verbal, somatic, or focus components are used during the creation of the spell formula. Any material, XP cost, or other components are used when the spell itself is invoked.
Next, to attempt to create a spell formula, an astrologer must have an Intelligence equal to 10 + the spell’s level and make an Astrology check. The total Astrology DC for creating a spell formula is 10 + the level of the desired spell + duration modifier + the target bonus (if any).
A formula remains effective for the length of its duration; it can be invoked at any time within its duration. Once the duration expires, the formula expires as well, and the spell can be no longer invoked. Duration is chosen by the astrologer, and modifies the DC of the Astrology check for creating a spell formula as listed in the table below:
|Solar diameter*||3 minutes||–5|
|Solar phase||Next sunrise or sunset, whichever comes first||+0|
|Lunar phase||3 days (at moonrise)||+5||Requires fetish|
|Lunar month||Until current lunar phase repeats (at moonrise)||+10||Requires fetish|
|Season||Next equinox or solstice, whichever comes first||+15||Requires fetish|
|Solar year||4 seasons||+20||Requires fetish|
* A “solar diameter” is the time it takes the sun to travel its own diameter across the sky. Invoking the spell does not require being outdoors or in daylight.
An astrologer can also specify a target for the spell formula if the target remains within the astrologer’s sight during the time it takes to compute the spell formula, or if the astrologer has some knowledge about or connection to the target. If a target/subject is specified, invoking the spell against anything else results in automatic failure. Specifying a target earns bonuses to the Astrology check for computing the spell formula, as shown in the table below:
|Connection to Target/Subject||Check Bonus||Stackable?||Special|
|Self||+10||No||Spells with target “You” do not gain bonus|
|Target name||+2||Yes||Applies to known creatures, objects, and locations*|
|Target birthplace||+2||Yes||Applies to creatures known** and objects|
|Target birthday||+5||Yes||Applies to known† creatures, objects, and buildings|
|Possess part of target||+5||Yes|
|Possess target’s||+10||Yes||Must have nativity interpreted/created nativity|
* Examples: “Arith the Dracon,” “Mount Greylock,” “Orb of Asphodel,” etc.
** The “birthplace” of an object is the location in which an object was created.
† The “birthday” of objects is the day their creation began. The “birthday” of buildings is the start of their construction.
†† Examples: a picture, sculpture, written description, etc.
††† Examples: blood or a lock of hair for creatures, a piece of masonry for locations, a sliver of wood or metal for objects
Other connections may also provide bonuses at the GM’s discretion.
Once the Astrology check has been made, taking these modifiers into consideration, record the check result if successful. If the check fails, the astrologer abandons the formula after spending a number of minutes equal to the modified DC. In other words, it takes the DC amount in minutes for the astrologer to realize that he made a fatal error in computing the formula.
If the Astrology check succeeds, the astrologer finishes the formula in an amount of time no greater than a “base time” of DC x 10 in minutes. If something interrupts the formula’s creation, the astrologer makes a Concentration check against a variable DC as if casting a spell. If the Concentration check fails or if the astrologer voluntarily stops computing, the spell formula automatically fails. If the Astrology check is at least twice the DC, the formula takes half the base time to complete. If the Astrology check is three times the DC, the formula takes a third of the base time, and so on.
Astrological Fetish: A spell formulae with a duration longer than a solar phase requires the creation of an astrological fetish. Fetishes are intimate constructions that cannot be made for other characters. Only the fetish’s creator can invoke the spell contained within.
An astrological fetish is a small assemblage of materials designed to capture stellar arcane energies for later use. Fetishes can easily fit in the palm of a hand, and astrologers typically wear them about their necks, pinned to their clothes, or even wound into their hair. Typical components include burnt incense or aromatics, rare wood, polished rocks or minerals, strips of fine cloth or ribbons, and bits of bone and leather. The cost of raw materials for a fetish is based on the level of the spell and the formula’s duration.
|Duration||Raw Material Cost|
|Lunar phase||Spell’s level in gp|
|Lunar month||Spell’s level in gp x 5|
|Season||Spell’s level in gp x 10|
|Solar year||Spell’s level in gp x 100|
For example, Asphodel carries 50 gp worth of fetish raw materials in a gunnysack. He wants to create a formula for a 3rd-level spell with a lunar month duration, requiring a fetish costing 15 gp. He pulls a handful of pretty baubles from his gunnysack, which now contains 35 gp worth of fetish raw materials.
The astrologer assembles a fetish during the spell formula creation process. Doing so takes no extra time. To invoke a spell contained within a fetish, the fetish must be touching the astrologer’s skin. If a fetish is destroyed before the spell can be invoked, or if the formula’s duration expires, the fetish is rendered useless. A useless fetish is worth at most one half its original cost in raw materials, less if damaged. Invoking a Spell: Invoking a spell formula can be faster or slower than typical spellcasting, depending upon the situation. Using a fetish while invoking a spell counts as a partial action (in addition to any other time requirements) that provokes an Attack of Opportunity.
Invoking any spell with a material or XP component takes at least one action. Spells with such components take their listed casting times.
A spell with a listed casting time of 1 action, however, is invoked as a free action, as long as no material or XP components are required. Verbal, focus, and somatic components are supplied during the creation of the spell forumula itself, and are not needed when the spell is invoked. Spells with casting times longer than 1 action take their listed casting time.
The DC of a saving throw against an astrologer’s spell is equal the Astrology check result for creating its spell formula.
Familiar: An astrologer can summon a familiar in exactly the same way as a sorcerer, with the same benefits.
Bonus Feat: Every five levels an astrologer gains a bonus feat. This feat must be a metamagic feat, an item creation feat (including Compute Spell Inception, or Create Spell Talisman; only an astrologer can take the special feat Create Spell Talisman from the alchemy section.
School Specialization Astrologers study the heavens’ effects on the different types of magic. An astrologer can specialize in a school of magic in exactly the same way as a wizard, except that astrologers cannot pick “illusion” as their prohibited school. Astrology magic is already weak with illusions, and astrologers gain no benefit from not studying the stars’ effect on them.
Extra-Planar Weakness: Although astrologers are masters of planar magic while in familiar territory, their reliance on the physical heavens cripples them when journeying to different realms of existence. While in any plane other than the Material, Astral, or Ethereal Planes, astrologers suffer the following penalties: after preparing a spell formula, the astrologer must make a Knowledge (the planes) check with a DC equal to the Astrology check result for creating the formula. If the Knowledge (the planes) check fails, the formula is useless and the spell formula per day slot is wasted. At the GM’s discretion, the DC and base time for creating spell formula may be increased to reflect the otherworldliness of the astrologer’s surroundings. If in a realm without a sky or stars, creating spell formula may simply be impossible. In addition, all spell formulae with a duration of solar phase immediately expire upon the astrologer’s entrance into the other-world.
