Legacy of the Elm King: Roll20 notes

Maps: 
The barn is not very big - a contemporary analogy might be a 2-3 car garage. The map fits on a page size of 8 wide by 9 high.  You may wish to double the size to 16x18 to accomodate the use of size S creatures.

The dungeon is meant to be used on a page size 21 squares high by 24 squares wide. However, given the cramped quarters and the fact that all opponents are small-sized, it may be better to double the map size to 42hx48h. The map is of sufficient resolution to support this.

Note that illumination details do not appear on the map as this can be better served by tools within Roll20. Pay heed to the positioning of light sources on the GM map that appears in the PDF. Pit traps and secret doors are also absent from the map - handle the reveals as you see fit.

Tokens: Given that claustrophobia is a theme, you may wish to run with a double-scaled map and double up PC tokens to make it easier to insert large numbers of (small) kobolds on the map.
