Iconic Encounters: Kobold Lair

From publisher blurb:

Iconic Encounters is a series of adventure sites that feature monsters and tropes we've known throughout the years. They are written to be easy to pick up and use immediately. They are stripped of setting or plot restrictions (though adventure ideas are provided) and are designed to fit seamlessly into your own campaign.

Kobold Lair features the crafty little monsters and their traps. It includes 7 traps, most brand new, and a complete lair with easy-to-use stats (for levels 1-3). Eight adventure ideas have been provided in case you don't have one of your own. While written for 5E it can be readily used for any edition of D&D.
