Investigator Advancement

The default Call of Cthulhu campaign materials use a system where Skills grow as a result of use, with no "point buy" mechanic or Sanity Points the way our campaign uses them. For further information on how Sanity points are gained and managed, please see the " While I have chosen to simplify the process (removing the random nature of it with and using a purchase and upgrade system) I think the "Use to Improve" concept is appealing and thematic, so our Investigator Skill Advancement rules is as follows:

• Skill Advancement Through Dramatic Usage

When the use of a Skill on an important or dramatic Skill check yields a result you find "interesting", put a mark in that skill's Check Box to note that you have tested your abilities. When your Keeper hands out Sanity Points, you may request that this ability improves as a result of your experience. If the Keeper approves, you can pay the Sanity cost to advance the Skill by another half-step. Now erase the mark from the Check Box.

• Skill Advancement Through Narrative Time Skip

When the Investigators are allowed a long period of recovery time (at least a month) Keepers may give you several Sanity Points to spend on the results of your recovery time activities. You may request that your Investigator has been rigorously practicing their Skills during this time, and if the Keeper approves, you may pay the Sanity cost to advance the approved Skills by as many much as you wish.

• Skill Advancement Through Trait Gain

Some rare situations exist where a Trait will alter a Skill, increasing or decreasing the amount that the skill modifier offers during Conflict Resolution. Such modifiers apply directly to the Investigator's skill, not to the Conflict Resolution roll, and so they do not violate the "One Positive, One Negative" rule for applying modifiers in Conflict Resolution.
