'''Engulf {{Ex}}:''' A worm that walks can choose to engulf an opponent who is no more than one size category larger than itself. The worm attempts to embrace its victim, and with a successful melee touch attack, the victim is immediately swallowed up and surrounded by a mass of vermin, taking 1d6 points of damage per two character level levels as the biting vermin nibble away. A victim who spends a full-round action can break free of the embrace and move up to half its speed away from the worm if desired, but can do nothing else. Otherwise, each round a victim remains embraced, it takes another 1d6 points of damage per character level. Swarms are immune to this attack.
