UsageLevelDamageReach
Engulf (Binding ST 24)No attack roll is necessary; the quarry may defend only by dodging and retreating. Moving through an SM+2 or smaller creature is an automatic slam. A victim who fails to dodge is pinned if smaller than the pudding, or grappled if equal or larger. Breaking free is a Quick Contest of ST (only every 10 seconds if pinned; on a 17 or 18 the victim cannot escape unaided); the pudding has +10 ST when pinning and +5 when grappling. Engulfed victims cannot breathe and begin to suffocate when out of breath. It can pin or grapple one foe at a time; others are pushed along in front of it unless they win a Quick Contest of ST. It may constrict an engulfed victim every turn at effective ST 24.no rollConstriction Attack, effective ST 24 (thrust 2d+1 crushing)C
Acid (Corrosion Aura)Always on, no attack roll. Any organic or metal creature or object touching the pudding takes 1d-1 corrosion per second; stone is unaffected. Engulfed creatures and objects take it as large-area injury. Selective, so it does not destroy what the pudding is not attacking.no roll1d-1 corrosion per secondC

  • GCS ancestry draft: gcs/black-pudding.gct
  • Source template total: 151 points.
  • Library-rebuilt template total: 151 points.
  • CER was computed from parsed Typical Stats using the Dungeons On Automatic baseline CER path.
  • Issue #5: the automatic engulf (Binding 24, constriction at effective ST 24) and the always-on corrosion aura were added from the source's stated mechanics.
  • CER recomputed from the reviewed Typical Stats through the canonical Dungeons on Automatic CER path: OR 44, PR 88, CER 132, threat tier severe.
  • Conversion baseline reported OR -3, PR 88, CER 85 (tier major). 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 1. 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-b3-cer-tails); GCS fidelity check passed, DOA playability check passed.
  • CER tail record. The rating was recomputed through the consumer CER path and the tail was read against package peers in review/reports/cer-audit.md; a floor of 1 reflects a genuinely feeble creature and a severe rating tracks the record's own HP, DR and damage.
