Half of every characteristic, a fifth of it, hit points, magic points, move rate, build and damage bonus all follow from eight numbers and an age. This sheet works them out while you type, so session zero goes on who the investigator is rather than on arithmetic.
The front carries the eight characteristics with their half and fifth values, the derived pools, and forty-six skills sorted into the language you opened the sheet in, each with its own half and fifth. Sanity and Luck stay yours to enter, because one starts at POW and the other is rolled. Under them sits a weapons table with damage, range, attacks and ammunition. The back is the part a character is remembered by: description, ideology, significant people, meaningful locations, treasured possessions, traits, injuries, phobias and the arcane tomes already read.
Export offers a fillable PDF: every box becomes a real form field, so a player fills it in any reader and sends it back. The same menu holds a blank copy, which prints the sheet with the skill list intact and every other box empty — the version to put on a convention table next to a pencil. Both are A4 at 300 DPI, as is the plain PNG.
Two hands to choose from: a 1920s sheet for the classic period and an Eastern Bloc one for a campaign behind the Curtain. This is unofficial fan material, not published, endorsed or approved by Chaosium. A book the investigator carried off is a Mythos Tome; the cutting that sent them looking for it is a Newspaper.
