Pros
Collection of fumbles and critical hit options for D&D 5th edition
Outcomes are well varied
Fits on one page for easy reference
Free!
Cons
Bleeding effect ending not specified in the description (this could have still fit on the page)
Too many options to remember (will need to use the one page reference mentioned above)
If you've been playing a while, you've most likely developed your own table if you like the idea
Introduction
Fumbles and critical hits are a classic part of D&D. I remember the very first game I played had one. The idea of players expecting something awesome after they roll a natural 20 is an iconic part of the game. However, sometimes the fumble and critical tables we are used to don't exactly translate over well to a new edition. For those of us who need a new set of tables, there is the 5e Critical Hit and Fumble Chart.
The Details
The chart is quite nice and straight forward. Not every option is equally likely and instead ranges on a D100 are given. As you can imagine, some criticals are better than others so such a setup makes sense. If you like most of the table but take issue with a couple of areas, this table makes a great starting point. You can just cross out the one that is there and add your own at the now freed slot. I also like how the last page has the entire contents of the file fit on one page. This makes it work as a great reference.
There are a couple of nice options as well in order to make criticals or fumbles less common as well as provide advantages to some classes. I like having extra options provided and considered, as anyone who has read my item descriptions would know.
Issues
Some of the effects mention bleeding but the description itself does not mention how to stop the bleeding. A clever Dungeon Master can use rules similar to alchemist fire or to other bleeding effects. However, be aware that the Dungeon Master will need to figure out the specifics (maybe you want a certain DC to be met before it ends). For some people, it's best that way. If you are newer and wanted it all written, you'll consider it incomplete.
The table isn't the kind of thing you memorize. Since there are many options and uneven number ranges, you will need to use the last page as a reference. However, since the author had the foresight to provide such a reference page, it's really only a minor issue at most. If, however, you are the kind of person who prefers to do as little looking up as possible, you might prefer to use the default critical hit and critical failure rules.
Conclusion
If you need a critical hit and fumble table for the current edition of Dungeons & Dragons, this is a good place to start. It's easy enough to modify but is generally fine as is. Be aware that you might need to come up with your own way to end the bleeding effects specified in the document. The last page is also easy to print and use as a reference. If you want to make your own, you may also want to look at this one for inspiration.
