Roguesknife

This rare herb grows in locations which lack sunlight, so it is unknown how it obtains nutrition. It is easily recognized by its sharp jagged leaves. Its unusual vein pattern mirror that of dripping blood and culminates to a deep crimson coloration at the tip. Merchants once traveled to distant places to obtain roguesknife, but modern greenhouses can simulate the required climate conditions for the plant. Each one takes years to fully mature and sells for a small fortune on the market
