I don't know how close it is to the original dungeon, but the stats are all for 3.5e, which would save you having to convert everything.

As for a map - I've never even tried an indoor map, that's a whole new learning curve.

It's where I got the map for my original Blackmoor map - the one that says 1977 Blackmoor Map.

The DA1 and DA4 maps use this exact map, just adding more locations.

The new Castle Blackmoor book details the whole dungeon, right to the bottom - but you DON'T want to go there! :shock:

A good rule of thumb is don't go lower than your character's level.
