Original GURPS conversion by Enraged Eggplant, from Monsters (May 11, 2024); adapted and republished with permission.
  • GCS ancestry draft: gcs/assassin-vine.gct
  • Source template total: 92 points.
  • Library-rebuilt template total: 92 points.
  • CER was computed from parsed Typical Stats using the Dungeons On Automatic baseline CER path.
  • Issue #5: the empty attack list was a parser limitation, not missing source mechanics. Constriction (Wrestling-14, thrust from ST 20 / KYOS ST 18) and the Binding 10 vegetation entangle were added from the source's stated mechanics.
  • CER recomputed from the reviewed Typical Stats through the canonical Dungeons on Automatic CER path: OR 19, PR 26, CER 45, threat tier standard.
  • Conversion baseline reported OR -1, PR 26, CER 25 (tier standard). 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 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.
