Frosthaven official companion app
Updated
Lucky Duck Games develops and publishes the companion. It is not a Snapshot Games product, and it is not a way to play the 138 scenarios.
Where to download it
Get the official companion on Steam. It assists a physical game; it does not play the campaign for you. The digital adaptation and soundtrack are separate products.
The listing supports multiple parties and campaigns, simultaneous multi-device synchronization, automated scenario monster/loot setup, opening scenario sections and tracking completion.
During play it sorts initiative, draws monster abilities and modifiers, calculates many movement/attack values, tracks HP/XP/loot/conditions, and supports summons, NPCs and all six elements. It advertises session resume, round undo/redo and custom monster sessions.
Editorial fit: use it for physical-session upkeep. Use campaign notes or the flowchart entry for campaign planning. Read special rules yourself: the developer claims coverage of the majority of scenario exceptions, not all.
Questions
Does it support the digital game's languages?
The companion's Steam table lists English interface only. The separate digital game's language table does not establish translations for this app.
