I think I figured out how to build Supernatural Durability out of spare parts

[Bruno]

As the thread title says, I think I figured out how to build Supernatural Durability out of spare parts. Or something a lot like it anyways.

Another thread reminded me that I don't like the vague built-in Achilles' Heel of "Occasional or better" frequency - when the Occasional flaw is priced the same as the Very Common one, that just offends my sense of consistency.

There's also the annoying overlap between SD and Unkillable - I just can't shake the feeling that a creature that wants Unkillable 2 or 3 shouldn't be paying full cost if they already have SD (or alternately they should have a discount on SD if they are buying full-fledged Unkillable).

So, doodling around, I have this build, coming out to 145 points if you don't use Multiplicative Modifiers.

Extra Basic Move +6 (Accessibility, Only below 1/3 HP and above -1 HP, -40%) [18]
Injury Tolerance: Unbreakable Bones (Cosmic, can't be crippled at all, +300%, Accessibility, Only when 0 HP or more, -20%) [32]
Immunity to Pain [30]
Immunity to Subdual [40]
Unkillable 1 (Accessibility, To -5xHT Only, -20%; Achilles' Heel, Some Occasional Thing, -30%) [25]

Notes:
Extra Basic Move +6 is to counter the halving of Move when you're dropped below 1/3 HP - but only until the new "below 0 HP" breakpoint. I chose 6 Basic Move for the generic template as a bit of an "everyman" value. Yes, the average person has Move 5, but folks with 150 point advantages tend to be a little exceptional at least, so I erred on the side of a little caution.

Cosmic, Can't be crippled at all, +300% was priced to make sure it cost more than the next best thing, which is Independant Limbs, Instant Reattachment, Reattachment Only (35 points). This puts the base cost of this version of Unbreakable Bones at 40 points, and then there's the Accessibility to make it line up with the way Supernatural Durability works.

Immunity to Pain, because they've got Immunity to Pain.
Immunity to Subdual, because that's the immunity to physical stun, KO, blah blah. Immunity to Subdual is from this thread. Feel free to replace with 20 levels of Hard to Subdue. This is a little overkill in some games, but it provides immunity to KOing or physically stunning spells, stupidly high level Malediction Afflictions of same, etc etc. In some games that really matters, in some games you might consider 10 levels to be "good enough" and never mind actual Immunity.

I feel pretty confident in the valuing of new non-Accessibility modifiers in this build; the Accessibility values were tweaked to try and get something close to 150 points in value that still felt vaguely defensible. That means they're sort of arbitrary, and I'd be happy with arguments that some of them are worth another -5% to -15%. If so, then Supernatural Durability might be overpriced by about 10% - that's not a bad margin of error for a big blob trait that's basically been grandfathered in from the previous edition.

Note that Immunity to pain allows you to completely ignore knockdown and stunning rolls, painful and stunning afflictions and so on.

So the immunity to subdual seems a bit useless..

And a smaller/alternative thing:

And as for the move: I would use the same method as is used to modify ST based damage to have modifiers for natural attacks.

That is: Pay for the difference in cost.

The effect seems about +50% cosmic in power(avoid drawback). Thus each move would cost 7.5 points, not 5.

So the cost would be 2.5 points*your move to make your move immune to a drawback.

However, it would be reasonable for full-on Immunity to Pain (in GURPS Powers: Divine Favor) to provide this benefit.

Consider Injury Tolerance: Diffuse (Only immunity to crippling injuries -80%)[20]

I also agree that it gives you additional options. For sanely played characters, this isn't the same as Immunity to Being Taken Prisoner . . . the fair cost of which would be the price of Warp (Accessibility, Only when taken prisoner, -40%; Reflexive, +40%) [100], or 100 points, because that's roughly what it does for you. Unconsciousness ought to be a rare cause of capture in plausible stories – most imprisonment should result from surrender by the prisoners, betrayal by their apparent allies, or (at its most violent) grappling and restraint. Thus, I'd be hesitant to price Immunity to Unconsciousness on the grounds that it's Immunity to Being Taken Prisoner. Mostly, it's Immunity to Being Bored While Waiting For Your PC To Wake Up.

Unkillable 1 isn't enough. People with Supernatural Durability only die from taking 10Xhp in one hit, or from their vulnerability, they can keep going past past -10xHP if neither of those conditions is met.

+300 -20 = +280, which gives total cost 3.8x base cost.

8 x 3.8 = 30.4, rounding to 31.
9 x 3.8 = 34.2, rounding to 35.
10 x 3.8 = 38.

I think that [32] has to be wrong.

I think Bruno is making use of Multiplicative Modifiers here.

[Bruno]

I did, indeed, screw that up. I didn't intend to use Multiplicative modifiers for that one, but I think I was sort of thinking of "uncrippleable limbs" as a new advantage.

I'm going over the other points people raised (this is what I get for doing rules stuff at night!) to see if I can turn over a better setup. I definitely should have reread the Immunity to Pain writeup first :P

There's exactly zero overlap between the two. Immunity to Subdual is trying to extend the Hard to Subdue advantage into an Immunity, which doesn't impact knockdown and stunning, painful afflictions, or anything else covered by Immunity to Pain.

Each level of Hard to Subdue gives +1 to any HT roll to avoid unconsciousness – whether as a result of injury, drugs, or ultra-tech weapons – and to resist supernatural abilities that cause unconsciousness.

I also rolled Immunity to Physical Stun into that, somewhat mistakenly, but since that seems to be included in Immunity to pain, that's handy. I presume Immunity to Pain does not actually provide immunity to Mental Stun, which GURPS tends to remember to qualify with the word... because that's stuff like confusion and fright, not pain.

Oh, well then that solves that problem. Makes the template annoyingly cheaper though.

I flat out refuse to (no offense). It can't cost less than being cripple-able but you can take one second to put a severed arm back on - after picking your arm up again, in combat. It has to cost more than that. Ergo, it has to cost more than 35 points.
The price for that is RAW, right out of Powers where that form of IT was introduced. Do we have an example for that Accessibility for IT:Diffuse?

(Now whether the 35 points is excessive is another question, but that's for another thread).

Ah, dangit. That interaction of conditions is much more complicated than I read it as last night.

Where does Supernatural durability say that you are immune to subdual?

Am I missing something in the text?

To my reading of the advantage it only seems to be Immunity to pain on that part.

Seems to be exactly Immunity to pain.
