Probe

The Probe is an enemy that spawns from one of The Destroyer red lit segments. It fires lasers both from inside the Destroyer and detached from its master. It can pass through blocks.

Probes will only detach from The Destroyer after it has taken a fair amount of damage.

Fighting Probes
Probes are fairly small, fast enemies that can deal consistent damage in a moderate amount of time. The best way to defeat them is to use a fast arcing weapon e.g. a broadsword or Light's Bane or better with high knockback and accessories to increase damage, melee attack speed and knockback. I warning you guys they are hard to kill if its 8 on one time so be careful when you gona kill it
