Roper

Aberration · SM +2 Roper (Enraged Eggplant; answers SRD 3.5, SRD 5.1)

A tall column of grey rock with one eye and a mouth, indistinguishable from a stalagmite until it opens either. It flicks out long sticky strands, drains the strength out of whatever they touch, and reels the body in unhurried.

Sharp TeethSharp Teeth (14): thrust 3d+1 cutting, Reach C.	14	thrust 3d+1 cutting	C
StrandsStrands (16): Most encounters with a roper begin when it fires strong, sticky strands. The creature can have up to six strands at once, and they can strike up to 20 yards away. This is a ranged attack that has Acc 3, Recoil 1, and uses the Innate Attack (Projectile) skill. The roper can vary this attack’s RoF from 1 to 6. If one or multiple strands were severed or released, the roper can replenish the lost uses by taking three Ready maneuvers (they do not have to be consecutive).	16	Most encounters with a roper begin when it fires strong, sticky strands.

Description

Written by Dungeons on Automatic, released under cc_by_4_0

• GCS ancestry draft: gcs/roper.gct
• Source template total: 179 points.
• Library-rebuilt template total: 179 points.
• CER was computed from parsed Typical Stats using the Dungeons On Automatic baseline CER path.
• Issue #5: 0 special ability construction(s) restored and 1 annotated with the source's stated cost. 1 save-or-disable construction(s) are scored through the affliction term at the source's stated point cost, or at Binding ST where the source builds the ability as a Binding.
• CER recomputed from the reviewed Typical Stats through the canonical Dungeons on Automatic CER path: OR 30, PR 25, CER 55, threat tier standard.
• Conversion baseline reported OR 19, PR 25, CER 44 (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.
• 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.
