Breath WeaponBreath Weapon (13): An air mephit may spend 1 FP to spew forth a blast of air and abrasive grit. This blast does 1d crushing damage, doubled, for the purposes of knockback only, plus 1 point of linked corrosion damage, and has a 1/2D range of 5 yards. It can also snuff out candles, sweep the floor, and so on. Against enemies with Injury Tolerance (Diffuse), such as gaseous beings and swarms, this becomes a much more potent attack, doing full crushing damage – including the doubling! Ignore the usual injury cap of 2 HP (Injury to Unliving, Homogenous, and Diffuse Targets, p. B380).	13	An air mephit may spend 1 FP to spew forth a blast of air and abrasive grit.

Notes

GCS ancestry draft: gcs/air-mephit.gct
Source template total: 122 points.
Library-rebuilt template total: 122 points.
CER was computed from parsed Typical Stats using the Dungeons On Automatic baseline CER path.
Review attacks, special abilities, encounter frequency, treasure, grappling, and GCS modifiers before approval.
Blurred Breeze: When the air mephit flies at Move 6 or faster, its form becomes blurred. Attempts to spot the mephit with normal vision and Infravision are at -4, as are attacks that rely on these senses. In addition, the mephit gains a +1 bonus to Dodge. This is a magical ability.

Source template total: 122 points.
Library-rebuilt template total: 122 points.
CER was computed from parsed Typical Stats using the Dungeons On Automatic baseline CER path.
Issue #5: 1 special ability construction(s) restored. No disabling construction on this record carries a cost the affliction term can score.
CER recomputed from the reviewed Typical Stats through the canonical Dungeons on Automatic CER path: OR 16, PR -2, CER 14, threat tier minor.
Conversion baseline reported OR 17, PR -2, CER 15 (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-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.
