New Biome Idea

I got an idea for a corrupted biome on the Sift, with black trees and dark blue leafs. I also thought about a new mob that lives in this biome, and its primary attack would be like a sonic explosion. When defeated, this mob would drop something simmilar to a totem, that would make you completely silent and would lose durability when you take dammage. Or it would drop something that we can process to use as a sonic projectile, and when used with crossbows it would make a sonic blast simmilar to the Warden's. I like more the totem idea, tho. Since now, thanks for reading
