Default The Hunter and Unkillable

Given that most local gaming groups are more active in that system, I don't have much opportunity to play GURPS. However, I find the cost-balance system of GURPS helps me stabilize and focus characters in the books I write. One of whom is a part-human hybrid who can be injured by mundane weapons, but heals very fast unless the weapon is silver (in which case it hurts a lot more and has a comparable healing time to average humans, with the caveat that he will heal from any non-fatal wound eventually as he can't bleed out). He's a self-styled hunter of these creatures, but I'm trying to figure out exactly how to build it so I make sure the ability is consistent as I write.

He isn't exactly supernaturally strong, but since the failure point of muscles is usually when they start tearing under strain he can continue to push his body past normal human limits and get back up to do it again, something he generally only uses against nonhuman enemies.

These are the (Dis)Advantages that I spotted in the main book that seem relevant, though I'm not sure how to best apply them.
  • Unkillable 1 (p95) never has to roll to avoid death is definitely fitting
  • Regeneration: Very Fast (p80) at least, but only for healing wounds from non-silver sources. Those heal slower, perhaps at standard rate
  • Regrowth (p80) could potentially apply, but none of the plot milestones ever deal with him having limbs chopped off. Most of his major injuries are impaling.
  • Resistant (impaling damage. common?) (p81) some manner of dividing mundane damage could help maintain a degree of parity with his compatriots, as he's joined by other humans who fight and are injured alongside him
  • Resistant (piercing damage. common?) (p81)
  • Damage Resistance (p47) while he's less likely to be stopped by mundane damage, I'm hesistant to use a straight subtractor because he can still be bruised and injured with the rest of his compatriots. Something more like "halves incoming damage" would seem more fitting because it would stop less lower-level damage but provide more protection against massive damage
  • Vulnerability (p161) multiplies the damage from that source, which is appropriate regarding the pain/shock taken from silver but doesn't reflect the fact that a 1kg straight-edged short sword would still only cut to a certain depth in the same swing.
  • Weakness (p161) bypasses defensive abilities, but causes damage at a distance like a radioactive isotope and doesn't reflect that it has to touch him.

It also means you can keep going until your body is physically incapable of functioning (-10xHP), which seems rather appropriate here.

GURPS Horror has the Bane Limitation, which can be applied to Advantages like Regeneration to make them not apply to damage caused by certain materials (in your case, silver). Worth a look.

Decide if he can actually regrow bits, or if the bits can simply never be chopped off in the first place. The latter is a form of Injury Tolerance found in GURPS Powers.

The Advantage you're looking for here is Injury Tolerance: Damage Reduction (which you might see on the forum mentioned as IT:DR). It's basically Vulnerability, but in reverse - see GURPS Powers.
To have it apply to two different types of damage, I'd personally figure out how much it would cost to be resistant to a larger class that includes those two, then mark it somewhere logical that's in between. Physical Damage would be Very Common and would include Crushing, Cutting, Impaling, and Piercing (Burning is more Energy, Corrosion and Fatigue are fuzzier but I'd probably lump them with Energy). I don't feel like looking up the actual values, but for sake of argument let's say IT:DR (Very Common) costs [40], IT:DR (Common) costs [30]. That's [+10] for +3 damage types, so each damage type is [+3.33] or so; IT:DR (imp and pi) would thus cost [34].

Alternatively, just give him Injury Tolerance: Unliving, which has built-in resistance to piercing and impaling attacks. In GURPS, what something does is more important than what it's called - while the character may indeed be alive, the fact that he lacks many of the vulnerabilities of the living makes this trait appropriate.

Again, IT:DR. In this case, you might be looking at unmodified IT:DR or IT:DR (Physical Only), with further levels of the trait against impaling and piercing damage.

Penetration is represented by basic damage, which Vulnerability doesn't modify. Your character isn't being cut any deeper by that silver sword, but the cut is hurting him more.

I think Weakness can be modified to require you to actually touch the object (actually, I thought it did that to start with, but I don't have my Basic Set books with me). Also, decide if it should actually harm him simply with a touch (It Buuuuurnsss!), or if it needs to hit him with enough force to cause injury.


Another trait you might want to consider (although I think it comes "free" with Unliving - you'll want to check) is Injury Tolerance: No Blood to represent the fact that he can't bleed out. He might actually have blood, making him susceptible to Blood Agents and similar. I believe that is a -40% Limitation on IT: No Blood (reducing its price to [3]).

Normal: impaling and huge piercing a wounding modifier of X2; large piercing, X1.5; piercing, X1; and small piercing, X0.5.

Injury Tolerance (Unliving) [20]: This gives impaling and huge piercing a wounding modifier of X1; large piercing, X1/2; piercing, X1/3; and small piercing, X1/5.

This doesn't effect special locations like the vitals or the brain. If he's ok being stabbed in those add:

Injury Tolerance (No Brain) [5]
Injury Tolerance (No Vitals) [5]

If he really doesn't mind being stabbed take Injury Tolerance (Homogenous). Impaling and huge piercing have a wounding modifier of X1/2; large piercing, X1/3; piercing, X1/5; and small piercing, X1/10.

This effects all locations and includes Injury Tolerance (No Brain) and Injury Tolerance (No Vitals)

Injury Tolerance: Damage Reduction Divides injury by 2, 3, 4, etc.

The rest was pretty well covered so Ill just hit this one.
Extra Effort can model this and maybe give him an ER so he can do it more.
Rules Exemption perk if no one else can use Extra Effort as well.

Default Re: The Hunter and Unkillable

Thanks for the pointers. I don't have GURPS Horror, but Bane sounds precisely like the vulnerability.

Advantages:
Unkillable 1 [50]
Regeneration: Very Fast (Bane, rare: silver) [90]
Regrowth (Bane, rare: silver) [36]
Injury Tolerance: Damage Reduction 2 or 3 [50 or 75]
Injury Tolerance: Unliving [20]
Claws: Sharp [5]
Discriminatory Smell [15]

Disadvantages (uncertain application):
Vulnerability (Characters 161) [10] describes "take extra damage from a particular attack form". While I think treating damage as multiplied with regards to shock is appropriate, I don't think it necessarily fits as far as doing more damage.
Susceptible (Characters 158) is an alternative, but the book description indicates it only applies to common things like poisons, metal.
Secret (Characters 152) [30] Psionics and a couple other books (as far as I remember) treat Secret as half the advantages lost and disadvantages gained, but the core book reads "Monster...hated and feared regardless of actual disposition...liable to be hunted on sight" which is appropriate for monsters that can destroy villages as his progenitor did.
Low Empathy (Characters 142) [20] He's not actually terrible at reading other people, but he's very bad at dealing with them in any constructive or supportive manner.
Distinctive Features (Characters 165) [2] The book specifies "of your race", but he appears to be human except for bone ridges along his cranium, claws, and orange reflective eyes.
Fanatacism (Characters 136) is a possibility given that he'd sacrifice himself or any of his comrades, but Code of Honor and Obsession already seems to cover his goal of hunting down monsters.

Disadvantages (clear):
Obsession (Kill all monsters, SC 6) [20]
Callous [5]
Frightens Animals [10]
Loner [5]
Nightmares [5]
Bloodlust (monsters must all die now, -10%) [9]

Attributes:
ST 14, DX 11, HT 12, IQ 9
Secondary Attributes:
HP 15, Per 13, Will 9, FP 12

Will comment on how he and Extra Effort interact later.

Consider something like Low Pain Threshold (Only vs. Silver -80%) [-2]

Given that he recovers from the strain of Extra Effort really fast, why not take Fatigue Recovery +100% on his Regeneration? He would recover 1 FP per second without rest that way.

Like for example let's say you buy Regeneration up to 1 HP/minute normally, but then you pay the difference from minute>turn with the bane limit on that difference.

Say you have 100 HP, you take 10 damage from your bane, then 50 damage from some other stuff.
First heal the normal injury in 50 seconds, then the bane injury at a rate of 1 hp per minute: total time to recovery 10 minutes, 50 seconds.

Secondary Attributes:
HP 15,
If you drop Injury Tolerance: Damage Reduction 2 [50]; you could buy +25 HP (Massless +0%) [50] which more than doubles your HP.

If you drop Injury Tolerance: Damage Reduction 3 [75]; you could buy +37 HP (Massless +0%) [74] which more than triples your HP.

Low levels of Injury Tolerance: Damage Reduction are a bit rubbish if you don't have a lot of HP.

They don't overlap. Heal all the fastest healing injury type first, then the next fastest healing injury type, and so on.

No. GURPS Healing is sequential not simultaneous. You could heal 59hp at 1 HP per second, but then you need a whole other minute to heal 1 HP at 1 HP per minute, making the total time 1 minute 59 seconds.

You don't count the healing time from when you were injured, but from when you healed the previous HP.

Not quite. Normal injury heals at a rate of 1 HP/second for you, while silver-inflicted injury heals at a rate of only 1 HP/minute. That means your normal injury should take 3600 seconds (1 hour) to heal fully, and your silver-inflicted injury should take 60 minutes (again, 1 hour) to heal fully. There shouldn't be any combination of healing rates (absent outside intervention, of course) where it takes you less time than the sum of those two times - a total of 2 hours - for you to heal up to full. Using your "59 normal, 1 silver per minute" rate, you're going to heal up to full in 1 hour, 1 minute. That's clearly wrong.

The simplest way to handle it is, as NineDaysDead suggests, to heal the quickest-healing injury first. If the visuals of this - wounds from silver weapons not even starting to close until all other wounds are gone - bothers you too much, you could split the healing up so that you recover 1800 HP normal injury and 30 HP silver-inflicted injury in an hour. You'll overall recover at the same rate (still takes 2 hours to get back up to full), but instead of 1 HP per second followed by 1 HP per minute, you're recovering 1 normal HP per 2 seconds and 1 silvered HP per 2 minutes simultaneously.

(EDIT: Of course, I should note here that your situation is purely theoretical. Regeneration actually scales with HP, just like natural healing, so Fast Regeneration would give you a rate of 366/minute, Very Fast Regeneration would give you a rate of 366/second. With some work, you might be able to figure out fair costs for 1/min and 1/sec for your HP, however.)
