AMAZING!!! I've always been interested as a player in skinning and butchering monsters and this supplement gives me everything i could want!
The supplement is very well written, has great art and gives you all the pertinent info you need without being overly complex or difficult to use, the items and gear provided in the supplement are very cool and thematic and they give both players and dms a great springboard to come up with new items, this supplement is also fairly easy to adapt to new monsters or homebrew monsters making quite flexible for dms and players.
Over all i fully recommend this supplement, for 1 dollar this is a steal, i would gladly pay 5 to 10 dollars for a supplement of this quality.
5 stars all day long!!!
