Hadopelagic Sound Wave

A single uninterrupted burst from the Hadopelagic Echo, followed by two bursts against a set of Target Dummies. Note how the sound waves slow down with each successful hit until they stop completely.

The Hadopelagic Echo is a craftable post-Moon Lord magic gun that is a direct upgrade to the Eidolic Wail. It fires a burst of four sound waves that can pierce infinitely and ricochet off of walls in quick succession. When the wave hits an enemy, it spawns two additional waves from random directions, with a 2-second cooldown on the effect. The main wave initially deals 5% damage with a smaller size and grows to full size and damage after one second, while additional waves deal 20% damage.

Its best modifier is Mythical.
