| TrumpetA trumpet archon can blow its trumpet to create an awe-inspiring noise, causing everyone who hears it to make a Fright Check at -3. The archon can exclude any beings from the area of effect. If a victim succeeds at his Fright Check, he will be unaffected by the archon’s Trumper for one hour. Use Awe check table from GURPS Powers, page 85, if possible. The trumpet can be taken away like any normal weapon. The trumpet has SM-2 and DR 6. It only works in the hands of the trumpet archon owner. | — | — | — |

- Original GURPS conversion by Enraged Eggplant, from Monsters (May 11, 2024); adapted and republished with permission.
- GCS ancestry draft: gcs/trumpet-archon.gct
- Source template total: 414 points.
- Library-rebuilt template total: 414 points.
- CER was computed from parsed Typical Stats using the Dungeons On Automatic baseline CER path.
- Issue #5: 1 special ability construction(s) restored (Trumpet). 1 save-or-disable construction(s) are scored through the affliction term at the source's stated point cost, or at Binding ST where the source builds the ability as a Binding.
- CER recomputed from the reviewed Typical Stats through the canonical Dungeons on Automatic CER path: OR 30, PR 17, CER 47, threat tier standard.
- Conversion baseline reported OR 22, PR 17, CER 39 (tier standard). The reviewed values come from the consumer CER implementation, which rounds damage once after the damage-type multiplier and credits ranged accuracy; the conversion baseline ceilinged the damage base first and ignored range.
- Encounter metadata derived (default): average number appearing 2, wandering weight 3. Encounter metadata derived for 0.2.0 from the reviewed threat tier and creature class (appearing: minor 4 / standard 2 / major 1 / severe 1, forced to 1 for solitary classes — including swarms, which are a single multi-body creature — and raised to 6 for gregarious minor creatures; wandering weight: minor 4 / standard 3 / major 2 / severe 1). The fan-conversion source states no appearing-in-numbers or wandering values, so these are derived, not source mechanics.
- Lair, treasure, and grappling remain unpopulated in 0.2.0 by package policy: the authorized fan-conversion source states no lair, treasure, or grappling values, and review declines to invent them. See review/policy/0.2.0-empty-field-policy.md.
- Review approved by automated-mechanical-review on 2026-07-26 (batch ee-2026-07-26-b4-special-mechanics); GCS fidelity check passed, DOA playability check passed.
- Special-mechanics record. Mechanics the CER path cannot price are named per record in review/reports/cer-audit.md rather than folded into the number, and encounter counts are capped where a save-or-disable attack is present.
