Wyvern

Dragon · 4 hexes · SM +2 Wyvern (Enraged Eggplant; answers SRD 3.5, SRD 5.1)

A lean flying reptile with two clawed hind legs, short forearms and broad membranous wings, its long tail ending in a barbed sting. It hunts alone and from height, dropping onto prey and driving the sting home; the venom will kill an animal its own size. It is bestial rather than clever.

Description

Written by Dungeons on Automatic, released under cc_by_4_0

• GCS ancestry draft: gcs/wyvern.gct
• Source template total: 228 points.
• Library-rebuilt template total: 228 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 39, PR 31, CER 70, threat tier major.
• Encounter metadata derived (solitary): average number appearing 1, wandering weight 2. 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.
