If the spittle hits bare skin of a living being, the being must make an immediate HT-2 roll or take 1d toxic damage. Every 10 seconds for 4 more cycles the victim must make another HT-2 roll to resist or take the same amount of damage. After losing 1/3 HP to this poison, the victim gets a -3 penalty to HT until he heals above this threshold.

- Credit
- Original GURPS conversion by Enraged Eggplant, from Monsters (May 11, 2024); adapted and republished with permission.
- GCS ancestry draft: gcs/guardian-naga.gct
- Source template total: 132 points.
- Library-rebuilt template total: 132 points.
- CER was computed from parsed Typical Stats using the Dungeons On Automatic baseline CER path.
- Issue #5: 1 special ability construction(s) restored (Poison Spit). 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 12, PR 16, CER 28, threat tier standard.
- Encounter metadata derived (solitary): average number appearing 1, 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.
