Overloaded Soldier

The Overloaded Soldier is a Hardmode enemy which can be found in the Underground layer and the Dungeon. It moves similarly to other Skeleton-type enemies, but its movement speed accelerates considerably the nearer it is to the player. It constantly emits a magenta glow, allowing it to be easily seen in dark caves.

After the Moon Lord is defeated, its stats are buffed and it begins dropping Phantoplasm, a versatile crafting material.

Trivia

 * It is one of two enemies which can drop Phantoplasm that spawn in the Cavern layer, the other being Phantom Debris. This is unlike the other phantoplasmic creatures which are only found in the Dungeon.
