What is this "critical failure" of which you speak?
I mean sure, you can add a house rule for critical failures, and I think it might have been an optional rule discussed in one of the sidebars (p. 28 of one of the DMGs, apparently; it comes with a lot of cautions, even then), but core 3.x editions didn't have any fumble mechanics. A natural 1 was an automatic miss on attacks, but it didn't carry any additional negative effects.
If you did add such a house rule, it might behoove you to also add in some sort of confirmation roll similar to that required for a critical hit. (So natural 1 --> roll again --I'd recommend at full normal attack bonus-- if a miss, then you have a critical fail; I don't care for the DC10 dexterity check in the sidebar I mentioned.) You might also rule that only the first or last in an iterative sequence could be a critical failure, meaning that there is only one chance to fumble per round regardless of your iterative attacks.
If you have fumbles (that do something meaningfully bad to the fumbling attacker), then the critical hits should be more meaningful, too, and not just extra damage. They should also occur much less often, in my opinion, than 1-in-20 times (modified by whatever confirmation rolls you have in place). More like 1-in-100 or 1-in-1000, or even less. If otherwise, then combats between (semi-)trained (quasi-)professionals becomes (once again, in my opinion) a bit too slapstick.
In general, this points to why I am not in favor of such house rules. I think fumbles should be left out. (Except possibly for weapon breakage in Athas, and I liked the 4e version there, making it a player choice with some benefit added on to tempt the player to make that decision, upon occasion.)
Just my thoughts.![]()
Personally -and as I've mentioned in other threads- I think the problem is the lack of a bell curve with a 1d20 roll and how that interacts with multiple rolls; not rules for fumbles and criticals.
I am someone who is in favor of such rules; though, I am in favor of them because I have played other rpgs in which they work and work well.
