Ferrous Wroughtnaut

Lost underground many years ago, these heavily armored knights are not men nor are they statues. Are they guarding something? They have forgotten what. Are they waiting for something? They have forgotten when. Are they mourning someone? They have forgotten whom. All they know is to slay those who approach their chambers. There is only one way to damage a Ferrous Wroughtnaut; its weakness in its back.

Only the bravest of adventurers would dare to challenge a Ferrous Wroughtnaut. Upon defeat, the Wroughtnaut will drop its Wrought Helm and its Axe of a Thousand Metals for the victor. Right clicking with the axe attacks in a large arc, and shift-right clicking will create a shockwave that brings targets closer to you. Neither tool can break.

Behavior
Ferrous Wroughtnauts start standing still, with their arms resting on their axe. When a player comes nearby or they are attacked, they ready themselves and start attacking. They are also immune to all sources of damage, except during their vertical swing attack.

When a Ferrous Wroughtnaut is attacking, it slowly marches towards its target, sometimes stopping to use one of the following attacks: When killed it drops a Wrought Helm and an Axe of a Thousand Metals.
 * Swing its axe in a horizontal arc after a short delay, dealing 30 damage to what it hits.
 * Swing its axe in a vertical arc after a short delay, dealing 30 damage to what it hits and getting its axe stuck in the ground. While the axe is stuck, the Wroughtnaut is vulnerable and may be damaged once in its back.
 * Stomp the ground with its foot, causing some nearby blocks to be launched upwards while dealing up to 6 damage to nearby mobs and knocking them a little away. Mobs closer to the Wroughtnaut take more damage and are knocked further.
