Doom-Flayer

The whirling globes of death known as Doom-Flayers were originally designed as mining devices. It speaks to the Skaven mindset that an enterprising Warlock observed the devastation they wrought on rock and immediately began considering military applications. Doom-Flayers now trundle along behind massed formations of Clanrats and Stormvermin, their operators revving the warp-engine impatiently. Eventually, their destructive urges overtake them and they gun the acceleration to churn a great furrow forward through the earth.
