Mastering Intrigue / Research / Using a Library

Research by Expertise

Source Ultimate Intrigue pg. 148
A successful Research check reduces a library’s knowledge points by a certain amount, just as a successful attack roll in combat reduces a creature’s hit points, and this amount depends on the primary researcher’s training in the skill she used for the Research check. A primary researcher reduces a library’s kp by 1d12 + her Intelligence modifier if she has either 10 ranks in the skill, Skill Focus in the skill, or both 5 ranks in the skill and the skill as a class skill. She reduces a library’s kp by 1d8 + her Intelligence modifier if she has either 5 ranks in the skill or the skill is a class skill for her (but not both). Otherwise, she reduces a library’s kp by 1d4 + her Intelligence modifier.

Alternate Ability Scores: At the GM’s discretion, a character with an ability that replaces her Intelligence score with another ability score for the purpose of Knowledge checks (such as a lore oracle or shaman) can also use that ability score instead of Intelligence to determine the reduction of kp. Beyond that, characters well suited for research in a particular library might modify the result of the die roll with a different ability modifier. For instance, a brawler or fighter carrying out research in a fighting school’s library might add her Strength modifier instead of her Intelligence modifier to the result. With the variety of options available to characters in the form of character classes, archetypes, prestige classes, and other customizable selections, it’s ultimately up to the GM to decide which characters are best suited for research in a particular library.

Character Class Variant: In this variant, how much a library’s kp are reduced depends on the researching character’s class, rather than on her training in the listed skill. For the purposes of this variant, character classes can be divided into three broad researcher categories: polymaths, scholars, and novices. Polymaths are characters with the ability to attempt any Knowledge check untrained, such as bards, loremasters, and skalds. A polymath reduces a library’s kp by 1d12 + the character’s Intelligence modifier with a successful Research check. Scholars are academic characters, including Intelligence-based spellcasters, alchemists, investigators, lore shamans, and lore oracles. A scholar reduces a library’s kp by 1d8 + the character’s Intelligence modifier with a successful Research check. All other characters are considered novices, being either uneducated or untrained in scholarly research. A novice reduces a library’s kp by 1d4 + the character’s Intelligence modifier with a successful Research check.

However, certain character classes might be better suited for research in specific libraries that have collections focusing on fields of study particularly relevant to those classes and their abilities. For example, a cleric or inquisitor researching in a religious library connected to her faith might be considered a scholar or even a polymath instead of a novice, or a cavalier or warpriest undertaking research at a famous war college might be considered a scholar while arcanists and wizards are treated as novices.
