Razorquills are omnivores, though they primarily hunt prey to eat and will only eat berries and bark if meat is scarce. Razorquills will snatch up bugs, domesticated Pieshu and other medium sized animals - though the most brazen of Razorquills may even attack lone Draken or Nyulop travelers.

They become particularly peckish around the months of autumn, digging their dens down further. These smart creatures will insulate their dens with what brush remains and sleep until spring. It is advised not to walk near wilted leafy patches in the forest when the snow falls.
