The game masters’ desktop app — by BlueDungeonCraft
Roll in One
The game master’s all-in-one workshop.
beta 0.1.0
Finely finished spell, monster and item cards, character creation, session management, text editor for scenario : Roll in One gathers everything you need to prepare your session.
Text is never cut off
A long spell continues on a numbered second card. Nothing gets truncated, ever.
Printing you can trust
A4 sheets set to the millimetre, colours designed for the printer: what comes out of the tray is what you saw on screen.
French and English
Every card exists in both languages, with the full SRD 5.2.1 text.
Editable end to end
Tweak a text, a school, a gradient: your homebrew gets the same finish as everything else.
Roll in Onebeta 0.1.0
One desktop app, the GM’s whole arsenal
Everything that ends up on your table starts here: you create, the app lays it out, your printer keeps up.
Cards ready to print
Spells, monsters, magic items: build your cards, adjust the text, pick the class — then print cut-ready sheets with crop marks, bleed and duplex.
Manage your ressources, and share them with the community
Use the ressources manager to organize your characters sheet, spells cards, items cards, maps, soundboards (and more!). Ressources can be printed and reused in any other scenario.
A complete character, no spreadsheet
Guided creation level by level: class, background, features, known spells. At the end, a clean sheet — and the character’s spellbook cards, ready to print.
Run the fight, not the paperwork
Initiative, hit points, conditions, monster stat blocks at hand: the session moves forward and everything stays readable — for you and for the table.
Packs ready to play
Spells, monsters, items, class features: finished content packs, laid out and printable as-is — enough to launch a campaign without losing the evening to prep.
