This is a series of blogs by Gargs454 to help DM's. I found the format easy to read, very useful and easy to reference. So much so that I created a wiki page for them so that new DM's to the game and this site can easily find and reference them. Happy Gaming

Trap Sense is a three part series of articles to help you make your monsters work with a trap to add to the table combat experience. I found them so good that I immediately printed them and added them to my DMG.
