I am really liking the Fifth Edition Foes from Necromancer Games. While writing my own adventures I find myself continually going to it to fill out the monsters for my encounters. However, one of the complaints has been that there is no table listing the monsters by environment. This past weekend I sat down and wrote up an excel spreadsheet listing all the monsters by terrain/environment. Here is a link to the spreadsheet. There are tabs at the bottom that list them by terrain.
