Enhanced Call of Cthulhu 7e Character Sheets can be exported as PDF documents - transposing your stats, skills, weapons, improvement marks and bio information into a pen and paper Call of Cthulhu character sheet for use offline.
For character that you own, the three dots in the top right of the sheet will have the option "Export to PDF".
Your device will then download the character sheet as a PDF in a Call of Cthulhu character sheet, saved as the name of the character sheet.
If there are multiple custom skills or weapons which is easy to continually add in a virtual setting, the PDF transposition is limited by the A4 character sheet space, and as such might not transpose perfectly.
Note: This is only available for character sheets you are the owner of, and is also an Enhanced Call of Cthulhu character sheet.
