Thorns

Thorns are large, spiky plants that grow all over the Thornlands and can sprawl into neighbouring biomes like the Highlands. Like a Cactus Block, touching Thorns will deal the player 1 () of damage. Adventurers have noticed that Thorns cannot be burned with fire, and breaking a Thorn block will only sprout more green Thorns. The only way to remove Thorns is to burn them with a Lamp of Cinders, then tap or walk into the charred Thorns.

Thorn Rose

Thorn bushes can also generate with Thorn Roses. These flowers can be harvested, but can only be placed on Thorns.
