Aberration · 4 hexes · SM +2 Water Naga (Enraged Eggplant; answers SRD 3.5)

Melee attacks

Usage	Level	Damage	Reach
Sharp TeethSharp Teeth (11): thrust 1d-1 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	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

Description

Written by Dungeons on Automatic, released under cc_by_4_0

• 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.
• Description text is original Dungeons on Automatic prose written from this record's own converted statistics and from the project's art direction for the creature. It is not derived from the authorized fan-conversion source, which states no creature descriptions, and not from any SRD. It carries its own authorship and CC BY 4.0 terms in the description field. See review/policy/description-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.
