Animal · 1 hex · SM -5 Bat (Monsters on Automatic; answers SRD 3.5, SRD 5.1)

A small brown insect-eater, common wherever there is a cave roof, a belfry or a hollow tree to hang from. Bats hunt on the wing in complete darkness, steering by sound, and one of them can do nothing whatever to a person. A whole roost coming out of a shaft at dusk is loud and unnerving, and that is the extent of it.

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.
  • 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/bat.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.
  • Longest dimension about 10 inches with the wings out, which is the published table's SM -5 row.
  • ST is the floor: an ounce 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.
