Animal · 1 hex · SM -2 Viper Snake (Monsters on Automatic; answers SRD 3.5, SRD 5.1: Poisonous Snake)

Under three feet, patterned into invisibility against dead leaves, and usually encountered by standing on it. A viper does not behave like a monster: it strikes once, it means it, and it leaves. The consequences arrive later, and they are what the party actually has to deal with.

Description
Written by Dungeons on Automatic, released under cc_by_4_0
  • Independently authored GURPS build. The SRD supplies the creature identity this record answers to and nothing else: no SRD statistics, wording or presentation is reproduced, and no third-party GURPS conversion was used as an input.
  • Answers the SRD heading(s): Poisonous Snake (SRD 5.1); Viper Snake (SRD 3.5).
  • Racial template: -95 points across 18 traits, plus 3 racial skill(s) worth 20 points.
  • Every trait is drawn from the project's controlled GURPS vocabulary in scripts/srd/trait-library.mjs, which carries the page reference and published cost for each entry.
  • sourceSystem is recorded as doa_fixture because that is the package contract's value for project-authored material; the SRD headings this record answers are in provenance.coversSourceIdentities.
  • Ratings are recomputed through the consumer CER path on every build, so a mechanics change cannot leave a stale rating behind.
  • Typical Stats, damage and ratings are derived from the racial template rather than authored beside it, so the sheet and the stat block cannot disagree.
  • GCS ancestry draft: gcs/viper-snake.gct
  • The published Move is the primary medium's cruising Move; sprint figures are stated in the movement note and not folded into it.
  • Treasure and grappling are not authored for this record and ship as explicit nulls, which reads as known absent rather than forgotten; `lair` carries a short habitat note instead, because where a creature dens is an encounter fact rather than a loot one.
  • Body mass is the figure the build was scaled from and the one fact that makes it checkable; see the gurps-animal-sanity-check skill for the bands.
  • About 3 feet, which is the SM -2 row.
  • Added after a post-hoc comparison against independent GURPS fan conversions of this creature: the Tracking skill, which a creature with Discriminatory Smell should always have. The comparison surfaced the gap; the build is still ours.
