This book is the perfect thing to have in your back pocket as a DM. Weather it's running a quick one shot or to spice up your campaign, this book has something for everyone. All of the ideas and conditions are easy drag and drop into almost any encounter, even if it's already written. I've used multiple of these in a campaign I'm running and even just picked some at random to run with some friends and we had a blast! Highly recommend checking this one out.
