Animal · 1 hex · SM -1 Giant Wolf Spider (Monsters on Automatic; answers SRD 5.1)

It builds no web. It waits in a hole with the lid held shut by one leg, and the first anyone knows is five feet of spider crossing open floor in two jumps. Faster than the web-builders, less armored, and much harder to see coming.

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): Giant Wolf Spider (SRD 5.1).
  • Racial template: -20 points across 23 traits, plus 2 racial skill(s) worth 16 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/giant-wolf-spider.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 5 feet across the legs, which is the SM -1 row.
  • Weaker than a spider of this size might suggest, deliberately: a hunting spider spends its build on speed, jump and stealth rather than on hauling prey.
  • Added after a post-hoc comparison against independent GURPS fan conversions of this creature: Peripheral Vision. The comparison surfaced the gap; the build is still ours.
