Breath WeaponBreath Weapon (13): A 10-yard jet of ice shards erupts from the mephit’s mouth. It uses Innate Attack (Breath) to hit. Don’t apply range penalties; treat this as a long melee weapon rather than a ranged attack. It does 1d small piercing damage, and has a 1/2D range of 5 yards. If any damage penetrates the target’s DR, he must make a HT roll, at -1 per 2 points of injury or suffer a -2 penalty to DX for (20 – HT) minutes as his skin and eyes numb. This ability costs 1 FP to use.	13	A 10-yard jet of ice shards erupts from the mephit’s mouth. It uses Innate Attack (Breath) to hit.

Chill MetalBy spending 3 FP, an ice mephit can spend 1 FP to use this ability on a metal object, making it very cold to the touch. This ability is resolved as a Quick Contest of the mephit's Will vs. the object's HT, penalized for range normally. It deals 1 point of burning damage per second to everyone touching it. This damage comes from extreme cold, not heat, so it cannot set anything on fire. Targets injured by this ability must make an HT roll, at -1 per 2 points of injury, or take a -2 penalty to DX and become Numb (p. B146) for (20-HT) minutes (minimum 1 minute). Useful when used on foe’s plate armor or metal weapon.	—	1 burning	C

GCS ancestry draft: gcs/ice-mephit.gct
Source template total: 103 points.
Library-rebuilt template total: 103 points.
CER was computed from parsed Typical Stats using the Dungeons On Automatic baseline CER path.
Issue #5: 1 special ability construction(s) restored (Chill Metal). 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.
GCS ancestry reconciliation adjudicated: the published template total is 103 points and the parsed source children sum to 81, a difference of +22. Classified as grouped construction not decomposed — consistent with grouped abilities the prose parser did not split into individual children (alternative abilities, linked constructions, and spell or breath-weapon groups). The points are real and priced in the author's total; only the decomposition is missing. The authorized source total is preserved; the remaining manual step is opening gcs/ice-mephit.gct in GCS to replace the reconciliation child with native constructions where the grouped ability can be decomposed.
CER recomputed from the reviewed Typical Stats through the canonical Dungeons on Automatic CER path: OR 5, PR 16, CER 21, threat tier minor.
Conversion baseline reported OR 4, PR 16, CER 20 (tier minor). 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 4, wandering weight 4. 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-b2-gcs-reconciliation); GCS fidelity check passed, DOA playability check passed.
The source-total difference is classified and documented in conversionNotes; the authorized published total is preserved and the residual stays visible as a reconciliation child.
Visual GCS verification of the .gct is not claimed by this decision; checks.gcsVisualPass is false.
