In the original incarnation of the edition, each die rolled that displayed a value of "1" was treated as a critical failure and canceled out a success, [@SgtSlayer]. Say the difficulty class was "6" and the character had four dice to roll, and they had rolled a "1", "5", "6" and a "3", their only successful roll was not only cancelled out, the entire roll went extremely bad due to a critical failure. It was further found by the optimization community that as the game scaled and the difficulty classes became harder, the more ranks a character had in their sum of skills meant it became disproportionately more likely to cancel out rolls. However, critical failures [i]also[/i] had the added negative that if one failed because of them, they became increasingly catastrophic for each failure and even more so with each critical failure. Failing to succeed is bad enough, failing spectacularly because of cancelled rolls combined with critical failures is exceptionally bad.

I am not certain if this was corrected in the revised edition versus the original printings. I almost wish to say it was not, although other corrections were made. Admittedly I have not spent much time checking the two printings against one another; the most I did with it was read optimization strategies and formulate my character around excelling at their role the best that they could and that was some of the material I came across. Supposedly, the general consensus was that White Wolf Publishing wrote excellent stories, not so much mechanics.
