| Usage | Level | Damage | Reach |
|---|---|---|---|
| HoovesHooves (15): thrust 3d+2 crushing (KYOS: 6d+2 crushing) + 2d follow-up burning, Reach C-1. Flaming Hooves: Burning Attack 2d (Follow-Up, Hooves, +0%; Magical, -10%) Resolve as stated by the construction; the source gives no separate resolution text. | 15 | thrust 3d+2 crushing (KYOS: 6d+2 crushing) + 2d follow-up burning | C-1 |
| FangsFangs (15): thrust 1d+2 impaling (KYOS: 2d+2 impaling), Reach C. | 15 | thrust 1d+2 impaling (KYOS: 2d+2 impaling) | C |
| Astral ProjectionAstral Projection (10): The cauchemar can leave its body behind, unconscious, while projecting its spirit to the Astral Plane by making an IQ roll and spending 1 FP. While there, it cannot cast spells or otherwise affect the world in any meaningful way. The spirit form is visible, but insubstantial. This ability can be maintained indefinitely, provided the cauchemar continues paying 1 FP per minute, but the body’s need to eat, drink, sleep, etc. effectively limits the duration to a day or so – longer if the body is left with friends, or otherwise cared for. | 10 | The cauchemar can leave its body behind, unconscious, while projecting its spirit to the Astral Plane by making an IQ roll and spending 1 FP.

| Nightmare AuraNightmare Aura (12): Every sapient creature within 4 yards of the cauchemar must roll a Quick Contest of Will against it every second or succumb to the nightmare aura. The victim of this aura gains the Nightmares (6) disadvantage (p. B144) for one day. The cauchemar may exclude any creatures from this effect. | 12 | Every sapient creature within 4 yards of the cauchemar must roll a Quick Contest of Will against it every second or succumb to the nightmare aura.

| SmokeSmoke (13): The cauchemar may fill a two-yard-radius area within 10 yards with bad smelling smoke. This gives -3 to all vision and Infravision rolls made through it. To place the cloud at a distance, it uses Innate Attack (Breath), with normal range penalties, but at +4 for affecting an area. The initial attack roll places the effect. It then drifts from that point with the wind. Every creature that inhales the smoke, begins to cough (is at -3 to DX and -1 to IQ, and cannot use Stealth) for 3 minutes, if it fails a HT roll. | 13 | The cauchemar may fill a two-yard-radius area within 10 yards with bad smelling smoke.

- GCS ancestry draft: gcs/cauchemar.gct
- Source template total: 431 points.
- Library-rebuilt template total: 431 points.
- CER was computed from parsed Typical Stats using the Dungeons On Automatic baseline CER path.
- Issue #5: 1 special ability construction(s) restored (Flaming Hooves) and 2 annotated with the source's stated cost. 2 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 35, PR 39, CER 74, threat tier major.
- Conversion baseline reported OR 24, PR 39, CER 63 (tier major). 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 1, wandering weight 2. Appearing count capped at 2 because this creature carries a save-or-disable attack that the CER path does not price; the rating understates how dangerous a group of them is. 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.
