You get a number of skill points to distribute among the skills of all of your characters equal to your point limit. The cost, in skill points, for various levels of bonus in a skill is as follows:
|Bonus||Total Skill Point Cost|
|Another +1||As above, ×2|
When making a skill check, roll a d10, add your current bonus in the skill, and compare to a DC. The DC for a skill check ranges from 3, for almost trivial actions, to 15, for almost superhuman actions. Unlike most other actions, a roll of 1 doesn't necessarily fail, and a roll of 10 only counts as 10.
Arcana: Understand magical effects. Determining which spell is attuned to a gem is DC 5, or DC 8 if the spell is multicolored.
Bluff: When lying, roll a bluff check to determine how hard it is to detect with Insight. You can also be Frightening as a standard action, affecting any number of creatures within 8 meters, or any one creature who can hear you; roll a Bluff check, and creatures with Insight greater than the check minus 5 are unaffected. If multiple creatures attempt bluffs to scare against the same target, that target is only affected by the highest roll of any such creature in the time since its last turn.
History: Remember past events, and the locations thereof.
Insight: Detect lies or attempts to impersonate others by rolling higher than the target's Bluff. Either of these things is a minor action, but can only be attempted once per statement or disguise. You can also use Insight to determine the best way to talk to someone, or to figure out what sort of offers they would appreciate.
Items: Identify, create, and repair items. You can detect when an object that malfunctions was sabotaged with a DC 8 Items check.
Legerdemain: Disguise sounds and motions you make as innocuous things by rolling at least equal to a target's Insight, if their Perception wasn't high enough to notice the action immediately. Also, use the Foil Search action.
Nature: Identify plants and animals, predict the weather, forage for food, cure the wounded. A keen knowledge of geography helps you estimate where things should be; find caves, figure out how the sewer system in the city would be arranged, and so on. You can recognize when a creature has been killed by poison or disease with a DC 8 Nature check. You can make the DC or GD Attack 2 points lower for a save against a poison or disease by caring for them for the Repeat Time of the disease and succeeding on a DC 5 Nature check.
People: Recognize important and powerful figures, and keep track of less powerful, but more personally relevant ones. Figure out how best to contact or locate individuals.
Scripts: Understand ancient or damaged writings. Make forgeries, which can only be seen as such with an equal or higher Scripts check. Make codes, which take a Scripts check 1.5 times higher (rounded up) than your check to decode without instructions; each check to attempt decoding takes as long as you choose to have it take a reader who does have the instructions.
Making Up Skill Checks
When attempting to perform some task not covered by the rules, it most likely should involve some number of skill checks. The DM is obliged to choose which skills and make up appropriate DCs and action costs as necessary. The DC(s) should be known to the players before they decide whether to actually attempt the action.
Rolling to Know Things
A large part of the function of most skills is the chance for characters to be more informed about their situation. Not all knowledge has the same significance, however. If a skill's knowledge function is described above, that overrides anything contradictory below where relevant.
Plot Hook Facts
There are things the DM desperately wants the players to know, like reasons to care about a haunted castle or vital clues to some mystery. This is a chance for the characters who specialize in that field to show their cleverness and exercise their own personal interests by choosing how to exposit the data, and how accurately to do so. The DC to know a fact of this type is 11, but if nobody succeeds, the DM is encouraged to either let the highest roller (or multiple if there's a tie) know anyways, or present the data via some other means.
There are things the DM desperately wants the players to figure out on their own, or only later in the future, like the solution to a mystery or that the local deity who all say must be obeyed is actually an ordinary soul-devouring monster. Sufficiently skilled characters should be able to deduce such things far sooner than most, so the DC for this sort of knowledge is no greater than 18.
Some information is merely potentially useful. For such knowledge, roll to determine how much the character knows. For facts about foreign nonlegendary topics, there is a -2 penalty to the roll, and for things that they could not possibly have already learned and would need to deduce cleverly, there is a -5 penalty to the roll.
|1 or less||You have no idea.|
|2-5|| You don't know the answer, but you know of a person or place|
you could easily visit to find out in a day or less.
|6-8|| You don't know the answer, but you know of a person or place|
you could visit to find out. Only trouble is, the information is in
enemy territory, expensive, or otherwise a pain to get.
|9||You don't know the complete answer, but you have some clue.|
|10+||You know the answer.|
If a character has already rolled to know a particular detail, they can never roll for that detail again. If they'd still like to discover the truth, they must do research or experimentation instead.
