Animal · 1 hex · SM -5 Bat [Monsters on Automatic, SRD coverage: mundane birds, fish and aquatic animals; answers Bat (SRD 5.1); Bat (SRD 3.5)]

A hand-sized insect hunter that navigates a pitch-dark cavern by sound alone and never touches a wall doing it. One is harmless. A roost disturbed at dusk is a wall of them coming out at once, which is worth a Fright Check and nothing else.

Notes

  • GCS ancestry draft: gcs/bat.gct
  • Independent build total: -101 points of racial traits plus 5 points of racial skills.
  • Answers the SRD heading(s): Bat (SRD 5.1); Bat (SRD 3.5). Only the creature identity is taken from the SRD; the GURPS statistics, ratings and prose are this project's own work and reproduce no SRD text.
  • Typical Stats, damage and ratings are derived from the racial template, not authored beside it, so the sheet and the stat block cannot disagree.
  • Body mass used to scale this build: 0.03 kg. ST, Size Modifier and DR are checked against it; see the gurps-animal-sanity-check skill for the bands.
  • Movement: ground Move 2; air Move 12 (primary). The published Move is the primary medium's cruising Move; sprint figures are stated here and not folded into it.
  • Treasure and grappling are not authored for this batch and ship as explicit nulls; `lair` carries a short habitat note, because where a wandering animal dens is an encounter fact rather than a loot one.
  • Longest dimension about 25 cm with the wings out, which is the published table's SM -5 row.
  • ST is the floor: 30 g of animal carrying nothing but itself.
  • Perception is only moderately raised. The bat's edge is not general alertness but one extraordinary sense, and Scanning Sense, Ultrahearing and Acute Hearing 4 are where that is paid for.
  • Ground Move is deliberately crippled: a bat on the floor drags itself.

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): Bat (SRD 5.1); Bat (SRD 3.5).
  • Racial template: -101 points across 18 traits, plus 2 racial skill(s) worth 5 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.
