There is a level 2 potion that lets you grow the ear points and height and build of an elf its impressively close to boom you are an elf in all appearance including someone pulling on your ears and so on.
Boom you look convincingly dead at level 2 is entirely reasonable if all you want is to look dead
Arguably I described that without a practice version of feigning death right here.
A level 2 item which all it did was a self only good bluff based on a different skill than bluff could still be ok. (I suppose you could still induce this in others either with a heal check or a diplomacy)
Though once you see it as actually reducing the need to breath and slowing and stopping heart beat I see it as very much moving in to the suppress needs and afflictions arena and level 4.
Then if we wanted Stasis Trance or Death Trance as a level 4 thing which you would also put all conditions on hold could be separated out and have Feign Death as a prerequisite is that kind of what you are thinking? Or make the level 4 effect a note on the level 2 version?
l estimate a level 10 from 4e higher in 4e - paragon and named level 8 or 9 serving the same marker points seem a definite correlation to me.
Looks like we agree more than you realizeie yes divide by two with an offset gets very close (that is linear)
level 30 from 4e becomes level 17 or 18 (approx maxed out)
level 21 from 4e becomes level 14 (gonzo epic begins)
level 11 from 4e becomes level 9 (named level)
level 1 from 4e becomes level 4 (level of feels competent)
AND level 1 from 1e becomes a minions downed in one hit which are not really recommend for players in 4e.
Sure, I think you can approximate it linearly well enough. There's no exact correlations, 4e characters are inherently a bit tougher and have slightly less open-ended abilities (but ones that in some ways are more powerful since you can use them so reliably).
Is something like what Li Mu Bai does in the end sequence of Crouching Tiger, Hidden Dragon really just a level 4 practice? I think being able to arrest the course of any affliction feels pretty 'epic' to me. Maybe in the fantastical world of 4e its only 'paragon', but it sure seems to me like Mu Bai is at least a paragon character, and I'd call delaying your last breath of life for several hours pretty gnarly stuff. Of course people can differ on things like that.
Here's how I scale things:
Heroic: characters are highly resistant, they have the hit points, HS, and skill bonuses needed to survive anything that would usually be considered survivable. So a heroic character will always survive a rattlesnake bite, all other things being equal, since most normal people would survive that with (or often without) some care. Often they can survive the bite of the black mamba, which is normally fatal to average people, but not universally lethal. They will still die from the bite of the green creeper of the Isle of Blight, nobody survives that, ever (but of course there's always a plot hook for this, maybe combined with a good check result in 4e).
Paragon: rattlesnakes break a tooth on you. The black mamba bite is still painful and partly debilitating without treatment, but survivable. The green creeper could still kill assuming lack of proper care and/or poor check results. Paragon characters survival ability is supernatural, but within the realm of folklore and the capabilities of 'the best in the world'.
Epic: rattlesnakes die when they bite you, black mambas break a tooth, the green creeper bite is painful but mostly just inconvenient. There are of course 'epic snakes' of some sort, the demon lord of snakes or something, that can still be lethal or at least debilitating, but nothing short of that is really going to touch you. Epic characters are simply beyond normal laws. Nobody has ever seen their like, except maybe in some myth of things that happened 2000 years ago.
I'd at least call Li Mu Bai 'paragon', nobody could survive the poison he's poisoned with unless they get some kind of cure-all. However he's a paragon 'monk' and he's got access to the practice 'arrest all negative effects, pay an HS every N hours to maintain this'. He's just running low on HS when Shu Lien finds him and can't hold out any longer.
That's my take on it. Note how this fundamentally differs from how things work in 1e, where a large centipede's poison CAN kill even a level 20 PC, albeit they will normally pass their save.
