| Breath WeaponBreath Weapon (12): A water mephit may spend 1 FP to spew forth a blast of water. This blast does 2d crushing damage, doubled, for the purposes of knockback only, and has a 1/2D range of 5 yards. It deals no injury, but deals knockback and blunt trauma. It can also snuff out flames. 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). | 12 | A water mephit may spend 1 FP to spew forth a blast of water.

- Original GURPS conversion by Enraged Eggplant, from Monsters (May 11, 2024); adapted and republished with permission.
- GCS ancestry draft: gcs/water-mephit.gct
- Source template total: 105 points.
- Library-rebuilt template total: 105 points.
- CER was computed from parsed Typical Stats using the Dungeons On Automatic baseline CER path.
- CER recomputed from the reviewed Typical Stats through the canonical Dungeons on Automatic CER path: OR 7, PR 1, CER 8, threat tier minor.
- 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.
