We're in definite agreement here, which is why replacing the extra damage seems like it should help players more often than it would hurt them. Against any random monster, most of that critical hit damage was probably lost to overkill anyway. For a player, a wounded-but-conscious PC is more fun than one which suddenly drops from running out of HP.I hope that works for you. I've never been a fan of the critical fumble rules, or effects like that from critical hits without some other form of buffer. 99% of opponents are disposable, so if one looses an eye it's no big deal. PCs are center stage, so when one of them looses an eye it's a big deal. While short term (a single battle) the effects are the same, long term the consequences of these systems are stacked against the PC's especially since critical hits are a flat 5% chance. Add in a second buffer like a confirmation roll and I don't have as much of an objection.
Here's the chart that I'm using. Roll d20 whenever you suffer a critical hit.From a players point of view Saelorn, I hope you pad the list a little bit and make the truly debilitating injuries a bit harder to get. But you know your game and players better than I ever could and I'm sure they trust you to be fair.
1-3) Left leg disabled: Speed reduced by half
4-6) Right leg disabled: Speed reduce by half
7-9) Left arm disabled: Cannot hold or use an item with that hand
10-12) Right arm disabled: Cannot hold or use an item with that hand
13-18) Broken rib: Make a Constitution (10) check whenever you would cast a spell, make an attack, etc; failure prevents you from acting
19-20) Concussion: Unconscious for 1d4 rounds, then Disadvantage on spells and Int/Wis/Cha checks
In every case, these can be cured with a Lesser Restoration. In essence, as long as there's a healer in the party, they'll go away after a long rest. I don't mind mandating magical healing for the party, since it means I can use the same basic rules to describe a world where NPCs have enduring broken limbs (as long as magical healing is not common).
