Able to blend into the dark stone of Vesper Crag, the Warmantid was massive, as large as a full-grown Warspider. Similar to a wingless Warfly in form, the Warmantid was described as having "a nest of clicking mandibles for a mouth". Like praying mantises, the Warmantid had a powerful appendage clasped to its upper chest with the strength to send an Elf into a backflip. Its eyes were bulbous, and unlike Warspiders, they were not the best targets for a bowman; a single arrow to the Warmantid's forehead killed it.
- The Warmantid was never named as a Warmantid in the book. The name is entirely conjectural.
- Aside from the Warmantid in chapter 40 of Venom and Song, other creatures of this breed do not appear in the books.
