Chapter 4: Skills

Knowledge Skills (Int)

Knowledge skills are those that are entirely informational or academic in content. The only tasks these skills are for are mental tasks involving no more than the recall and processing of information, and either verbally relating that information or putting it to paper with quill.

Note: You do not get retries on checks for any knowledge skill. The check represents what you know. A failed check means you never learned that particular fact, so a retry will not help because a second check doesn't let you know something you never knew to start with. You must do something to learn the fact before retrying.

Knowledge Skill
Source
Description
Arcana
PH
You are knowledgeable about the general principles and theories of magic, how it works, and what can and cannot be done with it. This is theoretical knowledge, which cannot be used to either cast spells or identify spells being cast. It covers topics such as ancient mysteries, magic traditions, arcane symbols and cryptic phrase. If you have 5 or more ranks of Knowledge (Arcana), it will provide a synergy bonus of +2 to any Spellcraft check made to determine the success of spell research.
Architecture
PH
You are knowledgeable about historical and current trends and styles in the design of buildings, aqueducts, bridges and fortifications. You can identify the particular style a building was built with, and you know what influenced that style. You know how to design buildings in a given style and draw clear and detailed plans for them in such a way that engineers and craftsmen can build based on them.
[Note: I have modified this from the original Architecture & Engineering skill listed in the Player's Handbook. These two are distinctly different fields. The gnome artificer prestige class in Magic of Faerûn lists them as separate prerequisite skills. Engineering is listed as a profession in the Conversion Manual, and engineering is far more of a profession anyway. See the Profession list for Engineering. Personally, I think Architecture ought to be a profession too, but I will stick with canon as much as reason allows me too.]
Astrology
Conv
[Note: This skill is superceded by Profession (astrologer), which was introduced in the Defenders of the Faith accessory.]

Illithid Lore
PsiH
You are familiar with the capabilities, habits, strengths and weaknesses of illithids. You know how to detect their presence, how to track them, and how to defeat them.

House

You know how to properly groom and dress, both yourself and others, in the latest style and fashion as well as where to find the truly essential items (jewelery, clothes, makeup, perfume, etc) to do so. You can often purchase these items for cheaper prices than others can, due to your savy shopping abilites and your familiarity with local merchants. Grooming itself takes at least an hour, longer for special occassions, and after that the character gains a +2 Circumstance bonus to her Charisma when dealing with individuals of her own race. Having 5 ranks in Parlor skills will grant you a +2 synergy bonus with Disguise checks.
[Note: This is partially a region-specific skill. See the note below on region-specific skills. If new to a place, you need 2d20 days to determine the styles of the current location, to find proper shops and to get to know the shopkeeps.]

Region-Specific Skills:
For all Region-Specific Skills you must designate a region. For example, Knowledge (Cormyr local) or Knowledge (Sembia local). Regions that are adjacent, overlapping or intertwined in some way may grant +2 synergy bonuses to each other if you have at least five ranks in the other skill. some Region-Specific Skills may not even allow you to use them for information concerning other regions, others will but may cause the DC of some checks to be more difficult than it would be if the situation had to do with a region you were more familiar with.
