Warden's sonic boom does melee damage

The warden's sonic boom doing melee damage makes no sense. This makes surviving the attack much easier due to it not cutting through armor.

How to reproduce:
1. Spawn a warden
2. Anger it
3. Evade it so that it uses its sonic boom
4. Get killed by it
Expected Result:
The death message would be either magic, explosions, or something unique
Observed Result:
"Player was slain by Warden"
