Thorns (Twilight Forest)

Thorns are a block added by Twilight Forest. It can only be found in the Thornlands. When there, the entire biome is overwhelmed by hundreds of thorn blocks, including leaves and thorn roses.

When a player comes in contact with Thorns, he/she will take damage (2 full hearts per tick, similar to Cactus). If he/she attempts to mine Thorns, they will turn into Green Thorns and grow towards the player, making the quest past them harder (Survival/Adventure mode only).

There is no way to obtain these blocks in Survival mode legitimately, they can only be spawned in Creative mode.

The only ways to get rid of Thorns are either:

- Using a Lamp of Cinders to turn them into Burnt Thorns, allowing the player to break or touch them and they will dissipate. - Have a Wither Boss shoot a skull into them, although this doesn't give you the blocks.

Successfully getting past the Thorns with the Lamp of Cinders will give you the achievement 'Past the Thorns'.
