The Thorns Gene gives entities a chance to reflect damage onto melee attackers. It only works if the entity's chestplate is either missing or Leather.

By default there's a 15% chance to inflict 1.5 points of damage (0.75 hearts) to the attacker when hit, using 1 point of hunger. These values can be changed in the server config.
