The Destroyer

. The Destroyer is a Hardmode version of Eater of Worlds boss, which was introduced in the 1.1 patch. It is summoned using a Mechanical Worm. Unlike the Eater of Worlds, however, it can only be summoned at night, and it is not limited to the Corruption. Though not limited to the Corruption, it is recommended to summon it while on the Corruption.

The Destroyer has a metallic-like body unlike Eater of Worlds which has a corrupted worm body. The Destroyer has red lights in its body, which are Probes that the Destroyer sends out. They are capable of firing lasers both from inside the Destroyer and detached from their master. If the light isn't lit up, that means Probe was already launched from that segment.

The Destroyer is a much different type of worm to fight unlike the others. His total health is shared throughout all segments of the body, not just one. The Destroyer also doesn't split like Eater of Worlds does (breaking into more segments of itself to fight the player), which means it will completely die when its health reaches zero.

Due to its massive health, it seems almost impossible to kill the Destroyer without end-game weapons and/or multiple players. However with end-game weapons, the Destroyer is the easiest Hardmode boss to beat solo due to the fact that it doesn't move out of the range of the player, allowing you to use high DPS melee weapons such as Excalibur.

When the Destroyer's health is low, it is recommended to wait until its head is near or within sight of the player before killing it due to his drops coming out of its head. This means that the drops may possibly be lost somewhere underground or high in the sky, and considering that the Souls of Might are not subject to gravity (just like the other souls), it may be difficult to find them if the players cannot keep track of his body links.
