Right now, the Lycan Wolves use the exact same Howl sound as Lycan does. Since it is only 1 sound file and one sound event, it just stacks up, getting really loud and peaking the sound.

Here you can hear how loud it gets when all wolves and Lycan are on the same spot upon cast.



Some suggestions:

1. Add multiple new howl sounds for the wolves (having 1 sound just makes them too identical, it just doesn't sound natural)
2. Add a random delay to the wolves' howls, instead of being perfectly synchronised (could do this for the sound only, or for the entire Howl effect around the wolves)
