JTmusic made that killer, I just did concept
DLC: Songs of Darkness
Map: recording studio
height: tall
range of terror: 36m
speed: 3.6m/sec
history: i think your their video of him is an appropriate story, except ending: When Killer Hook led Zayne to a dead end, he lifted the hook when in that moment a cold, thick fog appeared in the studio, with an orange-yellow portal between them, after which they both found themself in entity's dimension.
Power: song of the barkers: christian ames wanted to be the best singer ever, this wish was not only a gift but also a weapon. The Killer hook can create a huge sound wave, causing all survivors within range of terror to scream, revealing their position. after using Killer hook it increases its maximum speed to 175% for 15s. ability cools down after 60s.
metallic note: sound waves bounce off generators creating a chain reaction. when you damage a generator the 1/2 nearest generators will regress, (level 3) if there is a survivor working on one of them his aura will be revealed for 5s. perk renews after 100/90/80s.
painful beats: your songs give you strength with every soul knocked down. when you knock down a survivor all others within 20/30/40m get the effect exposed to 10/15/20. perk cooldown is 120/100/80s.
Hex: musical terror: the entity is losing control. When survivor throws pallet at you, it destroys automatically. the effect lasts until the hex is destroyed.
Add-ons:
Modded loudspeaker: ultra rare, after using the power all survivors in range are become injured instead of screaming.
oiled microphone: ultra rare, after using the power all survivors in range heve their auras revealed for 5s, the power's cooldown is longer for 20s.
(I'll try to make more add-ons sooner or later)
Well, that's all
