Hey IPF I just checked and I changed the sheet from 5th Ed to Roll20 Pathfinder 1st edition, BUT that was for an example of the Mad Mage Module. On the Curse of Strahd is says in the blurb on the market place "All Wizards of the Coast licensed content on Roll20 uses the Dungeons & Dragons by Roll20 sheet. The module will default to this sheet and we do not recommend changing it." But then if you just need the maps and have the printed book you could just buy the maps here on Roll20, but no tokens, just the maps <a href="https://marketplace.roll20.net/browse/gameaddon/343/castle-ravenloft-map-pack" rel="nofollow">https://marketplace.roll20.net/browse/gameaddon/343/castle-ravenloft-map-pack</a> Other things are also sold separate like the cards and such So make a new game, with a PF I sheet selected, then buy the maps and then make tokens as you change it to PF I rules. Could also risk buying the whole thing then try to switch to a PF I sheet but might be risky, but maybe someone else here has had success with that and could post up here hopefully?? Good luck on your game bud Tom
