Overview

The v.3.5 purple worm is an enormous underground magical beast, described as about 80 feet long and five feet across. In combat it coils to bring its mouth and poisonous tail into reach. Its bite first establishes a hold, allowing a later attempt to swallow the captive. The stomach inflicts both crushing and acid damage. A trapped creature can cut an exit, but muscular contraction closes that opening, so another captive cannot simply follow through it. These measurements and escape rules are specific to that older account.

The 2014 Monster Manual makes the worm a Gargantuan monstrosity with tremorsense and blindsight. It burrows through rock at reduced speed, leaving a ten-foot-wide tunnel that can become a route for others. A bite can immediately swallow a Large or smaller victim who fails a Dexterity save. The captive is blinded and restrained, protected from effects outside the worm, yet exposed to acid inside it. Sufficient damage from within can trigger regurgitation; death also permits escape from the corpse. The tail's sting remains a separate source of danger. The legacy entry lists desert and Underdark habitats.

The revised 2025 profile separates capture from ingestion. A bite grapples and restrains its target; a bonus-action Swallow then requires a Strength save from an eligible captive and allows up to three creatures inside at once. Rock tunneling persists, while the listed burrowing speed increases. Internal damage can still force the worm to disgorge its captives. This distinction matters for an encounter: being caught in its mouth is now a stage before swallowing, whereas the selected 2014 bite can complete both immediately. Neither edition's ten-foot tunnel should be mistaken for the older text's stated body diameter.

First appearances & development

This comparison follows the v.3.5 System Reference Document, the legacy 2014 Monster Manual, and the revised Monster Manual published in 2025. Their classifications and action rules describe different editions of the same named D&D creature. The retained 2000 manual is historical bibliography, rather than a newly inspected witness for these differences.

Canon & continuity

The complete dedicated v.3.5 SRD entry was read through its licensed third-party reproduction. The official D&D Beyond legacy and revised stat blocks were separately inspected, including any public description. The revised page identifies Monster Manual page 250. Full commercial manual chapters and campaign-specific encounter histories were not inspected.
