OMG! I remember this. Didn't own it. I see it's on Drivethru.Grimtooth’s Traps
Beat me to it, but yeah. I have his other two books even though I don't play 5e. They are very well done. If they are any indication of what this book will be, then I would highly recommend it. And get the others while you're at it.I would seriously check out Jeff Ashworthy's book of traps, puzzles and dungeons. I don't own it but if it is anything like his book of non player characters, then it would be an excellent resource.
