Spellcraft (Int; Trained Only)
You are skilled at the art of casting spells, identifying magic auras and items, crafting magic items, and identifying spells as they are being cast.
Arcana is used whenever your knowledge and skill of the technical art of casting a spell or crafting a magic item comes into question. This skill is also used to identify magical auras and the properties of magic items in your possession through the use of spells identify. The DC of this check varies depending upon the task at hand. Other specific uses of this skill are noted on the following table:
|Identify an aura while using detect magic||15 + spell level|
|Identify a spell effect while using detect magic||20 + spell level|
|Identify materials manufactured by magic||20 + spell level|
|Identify a spell that just targeted you||25 + spell level|
|Identify the spells cast using a specific material component||20|
|Identify a spell as it is being cast1||15 + spell level|
|Learn a spell from a spellbook or scroll||15 + spell level|
|Prepare a spell from a borrowed spellbook||15 + spell level|
|Identify the properties of a magic item while using detect magic or identify||15 + item's caster level|
|Decipher a scroll||20 + spell level|
|Craft a magic item||Varies by item|
|1 If you aren’t a spellcaster of the same type (i.e. arcane or divine) as the spell you are trying to identify, the DC to identify the spell being cast increases by +5.|
Identifying a spell as it is being cast is a free action that you can take even when it is not your turn, but you must be able to clearly see the spell as it is being cast, and this incurs the same penalties as a Perception skill check due to distance, poor conditions, and other factors. Learning a spell from a spellbook takes 1 hour per level of the spell (0-level spells take 30 minutes). Preparing a spell from a borrowed spellbook does not add any time to your spell preparation. Making a Spellcraft check to craft a magic item is made as part of the creation process. Attempting to ascertain the properties of a magic item using detect magic takes 10 minutes per item to be identified, or 1 minute if using identify, and you must be able to thoroughly examine the object. Identifying a potion in this way only takes 1 round.
You cannot retry checks made to identify a spell. If you fail to learn a spell from a spellbook or scroll, you must wait at least 1 week before you can try again. If you fail to prepare a spell from a borrowed spellbook, you cannot try again until the next day. When using detect magic or identify to learn the properties of magic items, you can only attempt to ascertain the properties of an individual item once per day. Additional attempts reveal the same results.

If you have the Magical Aptitude feat, you gain a bonus on Spellcraft checks.
