Transfering adventure from one ruleset to another

[Jimlock]

Hello,

Is it possible to use an adventure, initially designed for ADD, with the 5E ruleset ?

Or just copy the maps, with LOS included ?

There is an extension (Universal modules I think) which will allow you to open a module designed for one ruleset in a campaign using another ruleset. So, yes, you can open a 2e module in a 5e campaign. You'll only be able to use the images and story since they are common to all rulesets; you'll have to recreate encounters, NPCs, treasure parcels, items etc since those aren't common to all rulesets.

Thanks, indeed.

It works fine !
