Swarm · 1 hex · SM +0 Swarm of Bats (Monsters on Automatic; answers SRD 5.1)
Hundreds of them come out of a shaft at once and fill the passage wall to wall. Nothing in the swarm can do a person much harm on its own, and that hardly matters: nobody can see, nobody can hear an order, and the torch has already gone out.

- 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): Swarm of Bats (SRD 5.1).
- Racial template: 57 points across 18 traits, plus 0 racial skill(s) worth 0 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/swarm-of-bats.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.
- One hex of swarm; the individual is the Bat.
- Sonar is why a light does nothing to it. Darkness is not this creature's problem.
