List of worms and gastropods
Crawl's worms and gastropods are an assortment of enemies whose defining traits are moderately powerful attacks and mindless hunger. That said, they are generally quite slow and have virtually no defenses to speak of, so most characters will not find them terribly difficult to handle. Much like Crawl's arthropods, they are largely weak to poison and lack endoskeletons, meaning they cannot be raised as skeletons.
Most of them have been removed over time, as they presented few challenges to competent players. Those that remain are known for having dangerous abilities that easily compensate for their slow speed.
w Worm - These enormous pests can mangle inexperienced adventurers. They recover swiftly from injuries.
w Tyrant leech - Loathsome swamp-dwellers that gorge themselves on blood as they tear prey limb from limb.
