Vilespine

Vilespine is a plant added by Defiled Lands. It can be found in all defiled biomes, particularly in Vilespine Forests. It can be crafted into Arrows or Spiked Pellets.

It can only be planted on Defiled Dirt, Defiled Grass and Defiled Sand. It will slowly grow over time, similarly to Sugar Cane, up to 7 blocks tall. Any entity that isn't from defiled biomes will take damage when touching Vilespine of any size.

Trivia

 * The name "Vilespine" comes from a card named Vilespine Slayer from the video game Hearthstone.
