Melee attacks
| Usage | Level | Damage | Reach |
|---|---|---|---|
| Sharp TeethSharp Teeth (11): thrust 1d-1 cutting (KYOS: 1d cutting), Reach C. The victim that takes damage from this attack must make an immediate HT-2 roll or take 1d toxic damage. Every minute for 6 more cycles he must make another HT-2 roll to resist or take the same amount of damage. After losing 2/3 HP to this poison, the victim gains a -3 penalty to HT until he heals above this threshold. | 11 | thrust 1d-1 cutting (KYOS: 1d cutting) | C |
| Short SpinesShort Spines (7): 1d-2 impaling plus, Reach C. This is defensive weaponry, intended to discourage attackers; a water naga cannot use his Spines actively. However, it gets a DX-4 roll to hit each foe in close combat with it once per turn, as a free action. Roll at +2 against foes who attacked it from behind. Those who grapple or slam a water naga are hit immediately and automatically – and those who slam it take maximum damage! | 7 | 1d-2 impaling plus | C |

- Original GURPS conversion by Enraged Eggplant, from Monsters (May 11, 2024); adapted and republished with permission.
- GCS ancestry draft: gcs/water-naga.gct
- Source template total: 83 points.
- Library-rebuilt template total: 83 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 9, PR 14, CER 23, threat tier minor.
- Conversion baseline reported OR 10, PR 14, CER 24 (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 (solitary): average number appearing 1, 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.
