Great collection of different traps that would be easy to customize. I just like having some of the ideas to help get me started. Thank you!

It might be an odd criticism, but I always think that suggested traps should give an idea of what sort of treasure it would be guarding since I think the hardest part of trap design is not the design of the trap but coming up with a balanced reward that lies behind the trap

20 New Traps is a breath of fresh air in this edition that has deined to discuss traps as long as nobody asks any follow up questions.

Pros - Even if you never use any of the traps listed here, there are several creative and fun traps that give you ideas just for knowing about them. This is creativity at it's finest. I would start at the end because I did get a bit bored early on by large amounts of text describing something I already felt I understood. Fix this and add a Challenge rating I would happily give this a 5/5.

Cons - The information is all great. But the large blocky paragraphs are large, especially around several really good traps. If the traps were organized (Quick description, Perception, Trigger, Effect, etc) The information would pop right out and it would make skimming through take five seconds. The only problem I found with the book was that many of the traps left off Identification or Disarming rules. Which is probably 5e's fault more than James Introcaso's so while I would like that I wont hold it against him.

Best range of traps outside of the Dungeon Masters Guide. Information is well laid out and easy to use. Black/White artwork throughout the document adds to the ye olde flavor. DM's could use 5 of these traps in a campaign, or all 20. The traps range from classics like Crushing Room to new traps like the Grasping Arms.

You can tell a lot of work went in to this product. The descriptions are very detailed. A great selection of traps!

There are some really fun traps in here! You get gameplay stats for some old classics, like the "crushing room" or the "pendulum scythe," and you get some innovative and fun new ideas like the "withering tapestry." He also describes some ways players might disable (or trigger) traps with clever actions besides ability check rolls (though the DCs for those are included too) which encourages DMs and PCs both to think outside the box a little bit.
