Spellcraft

Description

Ability Score Used:	Choose One
Armor Check Penalty Applies?	No

Only Bards, Sorcerers and Wizards may learn this bailiwick skill. A character with the Minor Magic rogue talent may also learn this skill. No other class may place ranks in it unless they have an ability which specifically states they may put ranks into a bailiwick skill not normally offered by their class. A bailiwick skill is a skill that represents the core competency of a style of adventure, and has many useful applications.

The spellcraft skill is an expression of your practical knowledge of the arcane and its effects. For each rank a character places in spellcraft, the character receives a free rank in Knowledge (Arcana). Note that no character may ever have more ranks in a skill than her character level.

Each character class gains a single bailiwick skill at character creation, and this bailiwick skill is always a natural talent for your character. When you place your first rank in this skill, you must select one of your ability modifiers, and use that ability modifier as the key ability modifier for this skill. Once selected, this ability modifier may not be changed, except through the Reselection rules. Natural talent skills never suffer an armor check penalty, even if you associate that skill with your STR or DEX modifier.

If you gain a second bailiwick skill (usually through a racial trait), it is not automatically a natural talent (even though you typically get to choose which of your ability score modifiers is aligned to the second bailiwick skill). Armor check penalties do apply to the second bailiwick skill if you choose to associate it with your STR or DEX modifier, and you do not gain matching ranks in the linked skill for that bailiwick skill (in the case of spellcraft, Knowledge (Arcana)).

As with all skills, the uses below are merely suggestions, and by no means the full gamut of possible ways a skill can be used. Players and GM's are encouraged to find additional ways to use each skill.

Concentrate

To cast a spell, you must concentrate. If something interrupts your concentration while you're casting, you must make a Concentration skill check or lose the spell. The more distracting the interruption and the higher the level of the spell you are trying to cast, the higher the DC. Concentration checks are typically made for the following reasons (though other reasons may occur as well): to cast a spell while threatened by an enemy in combat to cause a spell to overcome the spell resistance of a creature to manipulate a spell which emulates a combat maneuver (such as Black Tentacles (Sorcerer/Wizard Spell)) to overcome the target's Maneuver Defense casting a spell while grappled or pinned Casting Defensively You can attempt to cast a spell while threatened by an enemy in combat, but it is inherently risky. This is sometimes referred to as 'casting while threatened', 'casting defensively', 'concentration check', or 'combat casting'. These terms are all effectively interchangeable, as they all refer to making a skill check to cast a spell due to being threatened by an enemy. Note that casting defensively cannot normally provoke an attack of opportunity. Instead, the spell either succeeds or fails, depending on the outcome of the check. The target DC of defensive casting is 10 + (spell level x 4). As a result, casting lower level spells while threatened is far less risky to a higher level caster than trying to cast one of their best spells while threatened. Overcome Spell Resistance You can use concentration to attempt to force your spells through the defenses of a creature which is immune to spells. Such creatures have a special ability called Spell Resistance, which means that all spells or spell-like abilities must first make a concentration check versus a DC of the target creature's Maneuver Defense, or the spell fails to affect that creature. This special ability is effectively an immunity to spells! However, as a big damned hero, you can focus your will, and try to blast through this defense anyway. You're just that much of a bad-ass. Manipulate Spell Effect Some spells, such as Black Tentacles (Sorcerer/Wizard Spell), emulate the effects of one or more Combat Maneuvers. As such, the effects of the spell go against the creature's Maneuver Defense score, instead of its Armor Class. Instead of using your own Might or Sleight of Hand skills to challenge your target, you use the power of your spell to manipulate your opponent on your behalf. You don't need bulging muscles and an obsession with high-protein diets to grapple monsters — you've got MAGIC! Spells which work inflict combat maneuver-like effects will also describe the need to use a concentrate check in place of might or sleight of hand in the text of the spell. Casting While Grappling If you are suffering under the grappled condition due to the actions of an enemy creature, you can cast a spell without any somatic components simply by casting defensively (see above). However, spells with somatic components require a Concentration check to cast, versus a DC of the grappler's Maneuver Defense, or the spell fails and the action to cast it is wasted. This Concentration check counts as the Casting Defensively check for casting the spell in melee (i.e. it is not in addition to a defensive casting Concentration check). Adverse Conditions If you are vigorously moving, in the middle of a violent storm, trying to stay upright on a tossing ship, or are otherwise being aggressively affected by your environment, you don't normally need to make a concentration check to cast a spell, because you're just that awesome. However, if you are attempting to cast a spell in the middle of a typhoon while on a sinking ship AND you are forced to make a concentration check for any reason, you suffer one or more penalties to the check due to the adverse conditions present.
Action Required:	Usually part of the same action as casting a spell
DC of Check:	Casting Defensively: 10 + (spell level x 4) Overcome Spell Resistance: the target's Maneuver Defense Manipulate Spell Effect: the target's Maneuver Defense Cast While Grappled: the target's Maneuver Defense
Modifiers to Check	Damaged During Casting: If you suffer damage during the act of casting a spell (usually due to a readied action), you increase the DC of your concentration check by +5. Bad Weather / Hazardous Environment: If you are in a terrible storm, or standing on a crumbling shelf in the midst of an earthquake, or any other adverse conditions that do not inflict damage each round, the DC of any concentration check is increased by +5. Dangerous Weather / Damaging Environment: If you are in a storm with flung debris, standing on a razor-sharp bed of shifting obsidian skree, or standing ankle-deep in an acid swamp, where you are suffering damage from the environment every round, the DC of any concentration check is increased by +10.
Take 10? / Take 20?	No (though some class features, feats, and abilities may allow this).
Allows Assists?	No
Results of Success	You successfully cast the spell.
Consequences of Failure	You lose the spell, just as if you had cast it to no effect.
Retry Allowed?	Yes, with a new spell. The spell of the initial attempt is lost, as though it had been cast.
Provokes AOO?	No

Identify A Spell

You can attempt to identify a spell or spell-like ability as it is being cast. This may provide useful information about how it can be resisted, or what secondary effects it might inflict. Identifying a spell as it is being cast requires no action, but you must be able to clearly see the spell as it is being cast, and this incurs the same penalties as a Perception check due to distance, poor conditions, and other factors.
Action Required:	Free action, which can be performed outside of your turn.
DC of Check:	10 + double the caster's level or CR
Modifiers to Check	Distance To Caster: Like perception checks, you take a -1 penalty to your spellcraft check to identify a spell being cast for every 10 feet of distance between you and the target (cumulative). Poor Conditions: Any conditions which hamper your ability to see the target, such as rain, fog, etc. inflict a penalty to your check. This ranges from -2 to -20, depending on how severely the conditions affect your perception of the target. A -2 penalty might be caused by several intervening creatures, while a -20 penalty might be caused by the target having total concealment from a source like Displacement (Sorcerer/Wizard Spell). The GM is the final arbiter of how badly the conditions affect your check. Note that any extraordinary senses you have, such as darkvision or blindsense should be mentioned to the GM when they are assessing this penalty, as they may significantly reduce or eliminate it. Specialist Wizard: If you are a specialist wizard, you get a +2 bonus on spellcraft checks made to identify, learn, and prepare spells from your chosen school. Similarly, you take a -5 penalty on similar checks made concerning spells from your opposition schools.
Take 10? / Take 20?	Yes
Allows Assists?	No
Results of Success	You successfully identify the spell or spell-like ability being cast.
Consequences of Failure	You are unable to determine what the spell or spell-like ability is.
Retry Allowed?	No
Provokes AOO?	No

Learn a Spell

You can scribe a spell into your spellbook, either from a scroll or from another spellbook. You can only learn a spell which is listed among the spells your class can learn (i.e. a wizard cannot learn divine spells).
Action Required:	1 hour per level of the spell (30 minutes for 0-level spells)
DC of Check:	15 + spell level
Modifiers to Check	Specialist Wizard: If you are a specialist wizard, you get a +2 bonus on spellcraft checks made to identify, learn, and prepare spells from your chosen school. Similarly, you take a -5 penalty on similar checks made concerning spells from your opposition schools.
Take 10? / Take 20?	You can take 10, but you cannot take 20.
Allows Assists?	No
Results of Success	You scribe the spell into your spellbook. It is now one of your known spells, and can be prepared as with any of your other known spells.
Consequences of Failure	You are unable to convert the spell into a formula you understand, and are able to cast. It is not copied into your spellbook, it is not a known spell for you, and you may not prepare it.
Retry Allowed?	If you fail to learn a spell from a spellbook or scroll, you must wait at least 1 week before you can try again.
Provokes AOO?	Yes. Don't try this during combat.

Prepare a Spell from a Borrowed Spellbook

You can attempt to prepare a spell from a borrowed spellbook. This is exactly like trying to prepare a spell in your own spellbook, except that there is a chance of failure. Even if you are successful in preparing the spell, the spell is not known to you, and does not count against your known spells.
Action Required:	Preparing a spell from a borrowed spellbook does not add any time to your daily spell preparation. You are assumed to spend about 1 hour each morning preparing spells, as part of your normal morning routine. You must have had a full night's rest before you can prepare new spells each day.
DC of Check:	15 + double the spell's level
Modifiers to Check	Specialist Wizard: If you are a specialist wizard, you get a +2 bonus on spellcraft checks made to identify, learn, and prepare spells from your chosen school. Similarly, you take a -5 penalty on similar checks made concerning spells from your opposition schools.
Take 10? / Take 20?	No
Allows Assists?	No
Results of Success	You may include the spell among your prepared spells for the day. If you wish to have it prepared multiple times (i.e. be able to cast it multiple times today), you only need a single successful check to do so. As with any prepared spells, if not used by the time you take a full night's rest, they are lost and must be prepared again.
Consequences of Failure	If you fail by 4 or less, you are unable to prepare the spell from the foreign spellbook. If you fail by 5 or more, or roll a natural 1 on the check, the spell is cast immediately with a minimum caster level for the spell. You have just enough control over the spell to choose its target yourself (though it must be a legal target within range of the spell). The spell is erased from the foreign spell book, just as though you had used it like a scroll.
Retry Allowed?	If you fail to prepare a spell from a borrowed spellbook, you cannot try again until the next day. If the spell was erased from the spellbook, you will need to find another copy of the spell to try again.
Provokes AOO?	Yes. Preparing spells is not something you should attempt during combat.

Identify Magic Item

You can use spellcraft to identify the properties and command words (if any) of a magic item you are holding. This is identical to the Divinity, Naturalism, Reason, Spycraft, and Warfare ability to identify magic items. It is also very similar to the Barter ability, except that it is faster. Spellcraft may also be used to assist another party member's attempt at determining the properties of a magic item, even if the other party member is using a different skill to make the check.
Action Required:	3 rounds per item you are attempting to identify
DC of Check:	10 + double the caster level of the item
Modifiers to Check	-
Take 10? / Take 20?	No
Allows Assists?	Yes (up to 5 allies).
Results of Success	Item is identified, including the command words (if any) needed to trigger its magical properties.
Consequences of Failure	Item is not identified
Retry Allowed?	You must wait 24 hours before retrying on the same item. Any attempts in the meantime always fail.
Provokes AOO?	Yes

Craft Magic Item

When combined with the Creator feat, spellcraft can be used to create magic items. In addition to the Creator feat, you must have the components listed in the magic item's 'creation' section on its description page. These items include a remnant, an item symbolic of the enchantment, and a gold cost equal to half the item's retail price. If the symbolic item being used has a monetary value, that value is subtracted from the gold required to craft the item. The creator feat and the gold cost are mandatory, but the symbolic item and remnant are not. You may attempt to craft the magic item with a lesser-tier remnant, or a poorly-matched symbolic item, or you can skip these items altogether. However, doing any of this causes the target DC to increase (see 'modifiers' below). You also need an appropriate place in which to work. The nature of such a place can vary wildly. A noisy pugilarium full of hard-training warriors might be ideal for a Brawler to work on his new amulet of natural armor, but it is probably not going to be a good place for a Sorcerer to get anything done. For users of Spellcraft, any place suitable for preparing spells is suitable for making items. Warfare works best in forges and smithies and training halls; rough, rude places of strife. Spycraft works best in hidden spyholes full of small secretive nooks and hidden tools. Naturalism works great in grottoes and caves and glades, anywhere the Nascent Seed is strong and vital. Divinity works well in temples and crypts and ossuaries, anywhere the sense of the Divine is strong. Reason works best in libraries and meditation halls, dojos and saunas, places where quiet thought is enhanced. If the workspace is considered a poor fit for the item being created, the base time required is doubled. If the workspace is inconsistent, or the item is being moved around between creation days (such as attempting to create an item while journeying overland), the required time is doubled again. Each day of crafting requires 8 hours of work, with no more than 1 hour of interruptions (not counting food and rest breaks). If you are unable to work 8 hours in a given day, the entire day's efforts are wasted, and not counted toward your progress. The days spent creating a magic item need not be consecutive. Partially finished magic items stored in a safe fashion will keep indefinitely. Since magic items in progress keep indefinitely, you may schedule time to work on one as you wish. Once you have determined the base number of days required to craft the magic item, you must craft the item for half this amount of time before you may make a skill check to determine the item's success or failure.
Action Required:	2 days, +1 day per creator level of the item being created. You can never reduce the time to create a magic item below 3 days, no matter how well you roll.
DC of Check:	The base DC of a magic item is 10 + double the Creator Level of the item being created.
Modifiers to Check	Quality Workshop: Using a workshop with very high quality tools and equipment lowers the DC by between -1 and -5, at the GM's discretion. Higher Creator Level: Attempting to create an item that has a Creator Level higher than your own level increases the DC by +2 per level of difference. Lower Creator Level: Attempting to create an item that has a Creator Level lower than your own level grants no bonuses. Lower Remnant Quality: Attempting to use a remnant of a lower quality than the remnant tier listed for the item increases the DC by +1 per tier difference. Higher Remnant Quality: There is no bonus for using a higher-tier remnant. No Remnant: Attempting to create the magic item without the remnant component increases the DC by +10. Excellent Symbolic Item: Creating a magic item while using a symbolic item that is highly relevant to the enchantment being created can reduce the DC by between -1 and -10, at the GM's discretion. Poor Symbolic Item: Attempting to create a magic item using a symbolic item that is a poor match to the enchantment being created increases the DC by between +1 and +10, at the GM's discretion. No Symbolic Item: Attempting to create a magic item without including a symbolic item increases the DC by +10. Rush Job: You may declare you are hurrying the work, reducing the base number of days required by 1 per +5 you add to the DC. You cannot reduce the creation time below 3 days, however. Careful Work: You may also declare you are taking your time, reducing the target DC by -1 per 1 extra day you add to the base time.
Take 10? / Take 20?	No
Allows Assists?	No
Results of Success	A result that is between 1 and 5 points less than the adjusted DC is considered an easy success, which increases the base time required by either 1 day or 10%, whichever is worse. A result that equals or exceeds the adjusted DC, by up to +4 above the DC, is considered an average success, and the base time to complete is unchanged. A result that exceeds the adjusted DC by between +5 and +14 is considered a challenging success, and the base time is decreased by either 1 day or 10%, whichever is better, to a minimum of 3 days. A result that exceeds the adjusted DC by 15 or more is considered an impossible success, and the base time is decreased by 3 days or 25%, whichever is better, to a minimum of 3 days.
Consequences of Failure	A result that is between 6 and 10 points less than the adjusted DC is considered a failure. A failure means that half of the material costs and the symbolic item (but no the remnant) are destroyed in the attempt, and half the base time (rounding up) required for the item is also wasted. A natural "1" on the die, or a result of that is 11 or more below the adjusted DC is considered a critical failure. A critical failure means that all of the materials, the remnant, and the symbolic item are destroyed in the attempt, and half the base time (rounding up) required for the item is also wasted.
Retry Allowed?	Yes, though you must procure new components to replace the destroyed ones, and begin the process again. You gain a +5 circumstance bonus on each retry after a failure, as you incorporate your new knowledge of what not to do.
Provokes AOO?	Yes. Don't try this during combat.

Learn a Spell by Seeing It Cast (Epic Use)

You can attempt to learn a spell simply by seeing it cast. This is very difficult, but allows a high-level caster to become very powerful indeed. Spontaneous casters, such as Sorcerers, must have fewer known spells of this spell level than their maximum in order to learn a new spell in this way. You must have a clear line of sight to the caster who is casting the spell you wish to learn. If the caster has any cover or concealment, in relation to you and your senses, you may not attempt this skill use. If successful, you must still scribe the spell into your spellbook as soon as possible, lest you forget the spell. This is an epic skill use, and requires at least 21 ranks in the skill before it may be attempted.
Action Required:	Immediate action to study the spell as it is being cast. 1 hour per spell level to scribe the spell into your spellbook, if you successfully learn it via this skill use.
DC of Check:	15 + quadruple the spell's level
Modifiers to Check	Distance: For every 10 feet between you and the caster casting the spell you are attempting to learn, the DC increases by +1. The first 10-foot increment does not inflict a penalty.
Take 10? / Take 20?	No
Allows Assists?	No
Results of Success	You are able to study the spell sufficient to scribe it into your spellbook. You must scribe the spell into your spellbook within 24 hours of a successful check, or you forget too much of the technique to record it. Scribing the spell into your spellbook follows the rules for Learning a Spell, above. You must be capable of adding a spell of this level to your known spells.
Consequences of Failure	You aren't able to catch all the nuances, components and changes in aura required to cast the spell.
Retry Allowed?	You need to witness the spell being cast again before you can retry.
Provokes AOO?	No

Cast Spell With Somatic Component While Grappled (Epic Use)

You can use spellcraft instead of a Caster Check to attempt to cast a spell with a somatic component while you are Grappled. Doing so is an expression of your will, and demonstrates a mastery of your aura that lesser casters are simply incapable of imitating. This is an epic skill use, and requires at least 21 ranks in the skill before it may be attempted.
Action Required:	Part of the action to cast the spell (typically a standard action)
DC of Check:	10 + quadruple the spell's level
Modifiers to Check	Careful Casting: You can attempt to cast the spell without provoking attacks of opportunity by increasing the DC by +10.
Take 10? / Take 20?	No
Allows Assists?	No
Results of Success	You cast the spell successfully.
Consequences of Failure	You fail to cast the spell, and the action to cast it is wasted.
Retry Allowed?	Yes
Provokes AOO?	Yes (unless you included the careful casting modifier, above).
