Glad to hear when folks make use of something I made! I made this based on the latest OSE version. I have the Dolmenwood version too but haven’t looked close enough to spot any consequential differences.
My recollection is that the only notable difference is that it adds a few more flavor details that tie it more strongly to the Dolmenwood setting.
I would lean more towards the DW version myself because it went through an extra round of edits, plus I plan to use it in a Dolmenwood campaign eventually. If you think you’re likely to ever run either DW or OSE, then get that version.
Sorry I can’t be more helpful at the moment. If you get the DW version and something is missing it doesn’t make sense feel free to ping me again.
