Note: the cover doesn't reflect the actual traps inside the booklet. lol (maybe one or two of the images.)
If i counted right, there's 28 Traps in this. (Edit: He updates this and adds more traps over time.)
My favorite things:
1) These traps are simple/easy to understand.
2) they're marked with a difficulty rating "not dangerous/setback?/dangerous?/deadly" and mentions character levels this trap can be for.
2) Description/ Trigger / Effect/ Countermeasures Its suuuuuper clear.
(Constructive Critisism: Please add this to the Trap called "Octonote". It's one long decription but it can be split into "Trigger"[Playing any other note...] and "Countermeasures" [Characters who succeed on a DC...])
Also for fun, I've written into the margin of some of these, to give it a reason to exist. "elf door/lock", "neat item", "bridge trap"..... and my favorite note is "Drunk Wizard". (I mean, come on. a good handful of these were totally created by a drunk wizard and they're awesome.)
These traps are clear, fun, silly, devistating,... its got allllll kinds. I recommend this list of traps to any DM to suppliment their game traps.
