Razor Grass (Basic Lore)

Razor Grass (Swarm; CR 9)
Neutral - Fine - Plant
This creature possesses the Swarm role, and therefore counts as 2 monsters for purposes of encounter size, XP award, and treasure. This monster frequently has the Swarm role, but may be set to different roles if desired. One of the worst vegetable menaces in the wide world is no less awful because it is also one of the smallest. Razor Grass is exactly what it sounds like, common grass. Except that razor grass is magical, and dislikes being eaten or walked on, intensely, and is sharp enough and animated enough to make sure that if you try to eat it, it eats you back. Even worse is the fact that razor grass is often found in large patches, as a swarm. Such dense growths of razor grass are incredibly deadly, and can be found in a wide variety of locations, even including as cultivated lawns in cities! The worst thing about razor grass is the fact that is nearly impossible to spot from a distance. Farmers have lost entire herds of cattle, their legs cut from beneath them and their bodies sliced into ground beef, without ever seeing a thing. And this in a nice field, with the grass no more than a foot high! Razor grass is incredibly fast moving for a plant, and in the right environment, telling the deadly grass from the harmless grass is nearly impossible. If razor grass is found near a settlement, drastic measures are taken, including burning all the grazing meadows. Nobody wants to get a grass infection going.
