The Wulfrum Amplifier is a Pre-Hardmode enemy found on the Surface during the day. It is completely stationary and, if approached, emits a field around it that will supercharge nearby Wulfrum enemies and increase their spawn rates by 5.5x. If a player enters this field, it spawns 1 / 2 Death Mode Wulfrum enemies. They spawn more frequently around the two outer thirds of the world.

While the field is harmless to any organic beings that pass through it, wulfrum machines are designed to receive energy from it which allows them to run at peak efficiency."
