Swarm of Bats - Dungeons on Automatic Bestiary

Swarm of Bats top-down flat-top hex token

Swarm · 1 hex · SM +0 Swarm of Bats [Monsters on Automatic, SRD coverage: swarms; answers Swarm of Bats (SRD 5.1)]

Hundreds of them coming out of a shaft at once, filling the passage wall to wall. Nothing in the swarm can hurt a person much on its own and none of that matters — you cannot see, you cannot hear an order, and the torch has already gone out.

Notes

GCS ancestry draft: gcs/swarm-of-bats.gct
Independent build total: 57 points of racial traits plus 0 points of racial skills.
Answers the SRD heading(s): Swarm of Bats (SRD 5.1). 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: 3 kg. ST, Size Modifier and DR are checked against it; see the gurps-animal-sanity-check skill for the bands.
Movement: ground Move 5; air Move 11, 16 at a sprint (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.
One hex of swarm; the individual bat is the Bat record in the bird-fish-aquatic batch.
Sonar is why a light does nothing to it. Darkness is not this creature's problem.

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.
