A creature swallowed by Dagon is assaulted by demonic enzymes, rasping talons, sucking tendrils, and vile gases. At the start of the swallowed creature's turn, it must succeed at a DC 41 Fortitude save or be nauseated, and must succeed at a DC 36 Will save or take 1d6 points of Dexterity and Charisma drain. Once the creature's Dexterity and Charisma are drained to 0, the creature transforms into a horrifically deformed version of itself that Dagon can then disgorge into any adjacent square as a swift action. The transformed creature gains the half-fiend template, its Dexterity and Charisma return to their normal values, and it is under Dagon's control (as dominate monster, caster level 28th). The transformation can be reversed by casting break enchantment and atonement on the victim during the first 24 hours (after that, it can be reversed only via miracle or wish). The Fortitude save DC is Constitution-based, and the Will save DC is Charisma-based.
