Aberration · 13 hexes · SM +3 Delver (Enraged Eggplant; answers SRD 3.5)

An immense slug plated in moss-green and copper mineral crust, with two broad paddle arms ending in blunt obsidian claws and a ridged sensory disk where a face would be. It eats stone and metal, dissolving a passage as it goes, and leaves smooth-walled tunnels that betray it long after it has moved on.

Description
Written by Dungeons on Automatic, released under cc_by_4_0
  • GCS ancestry draft: gcs/delver.gct
  • Source template total: 279 points.
  • Library-rebuilt template total: 279 points.
  • CER was computed from parsed Typical Stats using the Dungeons On Automatic baseline CER path.
  • Issue #5: 1 special ability construction(s) restored (Corrosive Slime). No disabling construction on this record carries a cost the affliction term can score.
  • CER recomputed from the reviewed Typical Stats through the canonical Dungeons on Automatic CER path: OR 14, PR 38, CER 52, threat tier standard.
  • 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.
  • 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.
