From publisher blurb:
Welcome to Expeditious Retreat Press’ newest PDF line, NPC Files. Each NPC File details one character from 1st through 20th level, giving game masters ultimate utility.
NPC Files are unique at their very conception. They begin with a story, tracing the character’s background, personality, and appearance at low level (level 2-5), mid-level (level 8-12) and high level (level 15-19) with their complementary stat block. Then their stat blocks are laid out 1st through 20th level, followed by familiars, mounts, and animal companions, as well as new magical items or spells (when appropriate).
The emphasis of NPC Files is mechanically describing a story-driven character. This means that sometimes they will incur experience penalties, sometimes they will have more or less than their expected wealth, and sometimes they don’t always take the “most efficient route” to their destiny. In short, they are like real people. We feel this is the real strength behind NPC Files.
There are certain skill checks that frequently arise in roleplaying, and we have included those skills in every stat block, regardless if the character put ranks in those skills. Such skills are listed in parenthesis after the ranked-skill listing.
