Amethyst spikes are structures that act as walls that inflict damage to players upon contact. When placed, mobs/players can't walk through it, which is very useful when running away from an attacker, or building a base. Amethyst spikes can only be broken by hammers or amethyst tools. Hammers are generally faster at breaking amethyst spikes than amethyst tools. Currently, it's the most damaging item in the game, doing 70 damage per second on contact... more than double the damage the dragon sword does per hit(30).
