Green Thorns

ModTwilight Forest
TypeSolid block

Green Thorns are a block added by Twilight Forest. They do not spawn naturally, but will be generated if a player attempts to mine the Thorns away in the Thornlands. It behaves similarly to Thorns, with the added trait of growing towards the player if they attempt to mine it. They can be burned away with the Lamp of Cinders.
