Resistant

Cost: Variable

Resistant is a mundane physical advantage where you naturally resistant (or even immune) to noxious items or substances that are not direct, physical attacks with possible resistance rolls.

Substance Resisted Against

• Very Common (Entire power source, Metabolic Hazards, Unconsciousness, Psionics if they exist) [30]
• Common (one particular focus, Power, or College of magic, Poison, Sickness) [15]
• Occasional (Disease, Ingested Poison) [10]
• Rare (Acceleration, Altitude Sickness, Bends, Seasickness, Space Sickness) [5]

Levels

Drop all fractions from final cost:

• Immunity - never have to make resistance rolls (x 1)
• +8 to all HT rolls to resist (x 1/2)
• +3 to all HT rolls to resist (x 1/3)

Comparative Pricing

Thanks to the collection of and additional rules for Perks, Talents, Enhancements, Quirks, and Limitations in the much of, if not all of, B118's "Designing Entirely New Advantages" is effectively obsolete.

For example, the breakdown of Rapid Healing as HT bought with "only rolls to recover from damage" reducing it to 1/10 cost, which violates the no less then -80% of cost rule on Basic Set p 110 is explained in Power-Ups 8: Limitations' Below the Minimum. It also explains the discontinuity that B79 established it actually applied to two things, the daily HT roll for recovering HP and the HT roll made to determine severity (duration) of crippling.

Similarly, the concept of any linear pricing was eliminated with rule revisions in Power-Ups 3: Talents, Power-Ups 4: Enhancements, and Power-Ups 8: Limitations.

Powers

GURPS Powers™, p. 71, discusses the relation between Resistant and power sources, while on p. 108, Resistant is mentioned as an advantage that can take the Force Field enhancement. On p. 167, it is mentioned in the Defending with Powers section, and in the Resisting Abilities section on p. 169:

It’s possible to buy Resistant against all resistible abilities of a given power, focus, or source

Examples

Basic Set

• Immunity to Metabolic Hazards [30]
• Immunity to Poison [15]
• Immunity to Sickness; Immunity (Disease) [15]
• Resistant to Disease (+3) [3]
• Resistant to Disease (+8) [5]
• Resistant to Seasickness +3 [1]
• Resistant to Seasickness +8 [2]

GURPS Powers

• 169 Resistant (Poison)

GURPS Martial Arts

47 mentions "Resistant to Chi Abilities" would be a "Very Common" category which anyone could enjoy at +3 but should have Trained By A Master for +8, while these would individually be Rare:

• Resistant to Hyponotic Hands
• Resistant to Invisibility Art
• Resistant to Pressure Points
• Resistant to Hand of Death attacks
• Resistant to Neck Injury (chokes and Neck Snap)

GURPS Horror

mentions coitophobia makes you immune to seduction

Demons have "Immunity to Mind-Affecting Magic [30]"

Magical Styles

• Spell Resistance defines "1 spell" as a rare hazard allowing +3 as a perk

Thaumatology

T63 Flawed Magic Resistance allows college limitations to lower the value, just like it did with Magic Susceptibility earlier.

This allows MR to go below 2/level if there's -50%

Psionic Powers

Tolerance defines a single psi ability as a 'rare' threat

Template Toolkit 2

• Hardened (common): Covers electromagnetic pulses, microwaves, and power surges. Pricing for Resistant (+8) is given as [7] when by Rounding rules it should be [8]
• Resistant to Influence Rolls (+3) [5]: Based on pricing this is considered Common.
• Resistant to Radiation [0]: generally limited to Unliving and Electrical beings/devices

Kromm Quotes

Sean Punch has commented on Resistant and Immune in the following posts to the SJG GURPS Forums:

• On resistance to "no resistance roll" effects, such as cyanide [1]
• On the difference between an attack not affecting something, and an immune defender [2]
• On how Resistance to All Influence Skills is equivalent to Indomitable for 15pts, allowing +3/+8 levels to be determined [3]
• Immunity to Unconsciousness is worth 30 points [4] which would make it a "Very Common" hazard. So +8 would be 15 and +3 would be 10.
  • "I'd split that further into refined (Diplomacy, Fast-Talk, and Savoir-Faire) vs. unrefined (Intimidation, Sex Appeal, and Streetwise), each with Immunity [10], Resistant (+8) [5], and Resistant (+3) [3]."
    • "An individual skill would have Immunity [5], Resistant (+8) [2], and Resistant (+3) [1]."
      • immunity to seduction is included in coitophobia!

• on Static being identical to immunity in 2014 [1]:

Static (Power Source) [30] (Powers, p. 98) is identical to Immunity to Power Source [30] (p. B81); it's just that Static has some special verbiage for powers and allows some special modifiers.
