Bloodied = Vulnerable. Given what we've seen about 4e, if you're not bloodied, it's extremely unlikely that you can die from a single attack or ability. However, once you're bloodied, one attack could kill you. You've used up enough of the "divine protection" or luck that hp partly represent.
And Second Wind is "I decide that I am suddenly no longer vulnerable" and technically I get back 30% of my hit points (or another amount)? I still cannot grasp/understand/imagine it, I'm afraid.
However, knowing that you're on the verge of death does allow some characters to perform special actions; the "if I'm going down, so are you" idea. Adrenalin does wonderful things.
Yes, that I can see. I can imagine someone who gets some kind of advantages once they are close to death (like some animals - forgot which ones - went raging once they went down under 50% or 20% of their max hp). I can very well see people close to death gaining some adrenalin surge which enable them to attack better, for more damage, perhaps more recklessly.
However, I can't see people suddenly gaining special attacks (like the yuan-ti's option to do a whirlwind attack) if
someone else becomes bloodied. That might be a fun/interesting technical rule, but it's not a roleplaying rule in my opinion. And I cannot really see my players accepting it either.
Consider an excerpt from a combat between two fighters and that yuan-ti.
- Fighter A: That last wound made me bloodied. Nevertheless, I walk to the yuan-ti and attack it! I hit for 12 damage.
- DM: Oh, great. Now that you are bloodied and next to the yuan-ti, it can perform a whirlwind attack against the two of you.
- Fighters A and B: Huh? Why? You mean he couldn't do a whirlwind attack before, but now he can just because Fighter A is bloodied and moved next to it?
- DM: Yes, yes, that's it.
- Fighters A and B: But why?
- DM: Erm... because it's a special yuan-ti's power. He... erm... kind of feeds off the fact that you are bloodied to empower his whirlwind attack.
- Fighters A and B: Allllright. Let's go find another DM.
I can very well see the same scene happen if the DM makes a dragon breathe "for free" as an "immediate" action just because it becomes bloodied. Or if the 20 enemy goblins all get a free shot at them because a goblin warlord shouts (in goblin) "Feather me Yon Oaf!".
