Has anyone used the lingering wounds rules from the DMG? I wanted to use this for an upcoming campaign, but I can't decide when to call for a roll on the lingering wounds table. If players roll when they drop to zero HP, most of the lingering wounds won't matter because they disappear after magical healing is received (which is what usually brings character back to 1 HP). If players roll when they take a critical hit, I feel like it would feel arbitrary and there would be nothing a PC could do to prevent getting his arm chopped off. Plus, crits would bias lingering wounds towards fighting large numbers of enemies. The alternative would be to roll for wounds when a PC takes more than half his health in damage, but that would bias fighting single powerful enemies over mobs of weaker enemies, and would also limit players ability to keep their characters safe from dismemberment.
As anyone used these rules and had any success?
