Yes you can. The character is hit by a spear and his goes negative. You describe "the spear is buried into your belly and you faint in pain with blood splitting out". He rolls 20, come back and use a second wind to recover some HPS. The player describes "The wound stops bleeding, I catch my breath and forgo the pain, get up and keep fighting". The wound is still there. Taking a second wind does not instantly and magically heal the wound, it just allows the character to stop being affected by it.Primal said:I think his main point was that when a PC falls to negative HPs, nobody, DM included, can predict whether he's just momentarily unconscious or dying. The fact is, in 4E you just become "unable to fight" and fall prone, but the DM cannot describe the effects of the last blow or the PC's condition in any way until those "recovery rolls" are done with.
"Guts spilling out" is very drastic and would be almost a killing blow. Anyway, using a second wind does not mean the guts came back in and the wound is gone. It means the effects of the wound are not affecting the character so much anymore. If you need a description for that: The character puts his guts back in, ties a strap around the waist to hold'em and keep fighting". That's very heroic IMO, maybe too much "unbeliaveble" in real world, but it's "believable" enough for D&D.For example, the effect would be laughable if you described how a blow leaves a character with "his guts spilling out", but he rolls a natural 20 on his next rounds recovery roll ("Guys, I'm just fine! A bit bloodied, but no lasting wounds!").
Hit Points have nothing to do with how healthy your character is. After an extended rest, the character recovered all his Hit Points, but he is still wounded, bruised, with bandages and other sorts of curatives all around the body. It would be silly if the wounds simply disappeared after 6 hours of sleep, it makes no sense. The wounds are still there, some of the pain is still there, they just aren't mechanically relevant to the game anymore, they don't need to be represented in the rules anymore. The wounds are not affecting the capacity of the character to keep doing his stuff.Especially as he only needs to rest for 6 hours to get to "full health" -- quite a feat if he's innards were hanging out.
A character with full HP is not woundless. HPs are the capacity of the character to keep fighting, not his capacity of being wounded.
