5E Player critical hits & fumbles

Is there a Fantasy Grounds version of this?

DM's Guild won't let me review this title, so I'm posting it here.

I picked this up because I was excited about seeing what someone had come up with for critical hits in 5E, a system I'm just beginning to use myself. Sadly, it appears that the text of this file is quite ambiguous overall. (I have to say, the titles of each of the mechanics are better than the DM's guide offered-- which was nothing.)

The "Mechanics" listed are ambiguous and really should be clarified. For example: "Opponent's AC is halved for all of the player's subsequent actions until the opponent is damaged by the player." with "all of the player's" and "until the opponent is damaged by the player" being the sort of problem found throughout this document.

Strictly read, that sentence tells me all players in the D&D group (who are all "the player" in a combat scene) attack the target at half AC value (which, in itself, isn't particularly logical considering...See more the multitude of numbers that correlate to one's AC), until any one of them hit the target. Strictly read again, this sentence also tells me that only the player that crit-hit the target gets this bonus against the target until the target is-- again --hit by that same player.

If these sort of ambiguities could be alleviated, and possibly add some conditions to the "Mechanics" beyond having advantage or disadvantage, this could be a much more interesting and useful contribution to 5E gaming.

As it stands now, a solid 3 of 5 stars.
