Consumstroyer

The Consumstroyer is a Hardmode boss intended to be defeated before the traditional Mechanical Bosses. It could be considered the Mechanical version of the Consumer of Planetary Bodies. It takes features from both the Destroyer and its pre-hardmode counterpart.

Summoning
To summon the Consumstroyer, the player must drop an Unidentified Voodoo Doll on the ground in the Purity biome at any time. The player must attack the dropped voodoo doll as if it was an enemy. Then, the voodoo doll will dissapear, and "Someone has been slain..." will appear in the chat. This does not cause any of your NPCs to be killed. 10 seconds later, the Consumstroyer will awake. This is explained in the lore.

AI
Unlike its predecessor, it does not have multiple forms. Instead, it varies between three attacks, a cursed flames attack, a charge attack, and a lazer attack. In its charge attack, it acts like the Expert Eater of Worlds, and tries to ram into the player. In the cursed flames attack, it flies above the player and launches cursed flames at them, similar to the Consumer's attack. It also sometimes circles the player like in a game of Snake and shoots lazers at them. In expert mode, he gets faster as he loses health, like WoF.

True Consumer
It acts similar to the Consumer, but fires a sword projectile similar to that of the Beam Sword and True Excalibur.

It deals 45 melee damage.

The Destrazer
It is a spelltome and upgrade to the Consulaser. It fires a green last-prism style lazer.

It deals 25 magic damage.

Destrucpeater
It is a repeater and upgrade to the Conshotbow. It shoots 3 arrows at a time, and each arrow has a 10% chance to inflict Cursed Flames.

It deals 28 ranged damage.

Consumstroyer Staff
Like the Consumer staff, it summons segments of the Consumstroyer. The segments act the same as its predecessor.

It deals 27 summon damage.

Mechanical Battery Upgrade
This is the expert mode exclusive item. It is soley used to craft the Mechanical Minecart MK2, which is crafted with the normal Mechanical Minecart and the Mechanical Battery Upgrade at a Mythril/Orichalcum anvil. The MMMK2 has a top speed of 142 mph while the Mechanical Minecart has a top speed of 102 mph.
