Victoria Rules
Given that the "Regeneration" spell has always been able to regrow lost limbs, I've never really had to think about this one very much as a DM. As player of the only character we've ever had manage to lose two different limbs in its career I also didn't have to worry about it. One was reattached during a drunken gonzo game where we met and destroyed some statues (don't even ask me why I was playing a 1-legged character!); during the combat we got hints that these statues somehow related to me so afterwards I picked up a stone leg and stuck it in place: voila! New leg. The arm I lost much later was regrown via the conventional Regeneration spell.
