How it works. A sheet auto-saves in this browser once it has a name. Renaming a sheet renames its save. Use the tabs to move between the three pages. Print prints all three pages of the current Agent, one per US Letter sheet, and Print Blank prints an empty set. Export downloads every sheet as a JSON file and Import merges a file like that back in (a sheet with the same name is replaced). Nothing leaves your browser.
Sample sheets. Load sample characters adds all 142 Agents from 142 Sample Characters (15 solo characters and 127 members of 29 groups, with each group's name and the rest of its roster under Languages & Contacts), replacing any saved sheet with the same name just as Import does and leaving your other sheets alone; you can also download the sample sheet file and import it yourself.
Worked out for you. These use the revised core rules with the July 2020 errata. Defence is Initiative − 1; Resilience is Toughness + 1 + your armour rating; Max Wounds is (Tier × 2) + Toughness; Max Shock is Willpower + Tier; Determination rolls Toughness dice; Resolve is Willpower − 1; Conviction is Willpower; Influence is Fellowship − 1; Passive Awareness is half your Awareness pool, rounded up. Wealth starts equal to Tier and Speed comes from your species (Human 6, Aeldari 8, Ork 6, Astartes and Primaris 7); type a value into either to override it. A skill's pool is its linked Attribute + rating. See Character Creation, Core Mechanics and the Dice Roller.
