War Scream/cry Of The Gods Problem

Recently I have been playing the Knight class, and I have noticed that the "Cry of the Gods" Spell, which is identical to War Scream minus the particle effects, causes opponents to glitch through walls a lot of the time. It also has extreme range and extreme knockback, sometimes, like I said, sending mobs through walls, and in some boss fights out of the map, to the point where almost every time I use this spell I have to restart the boss fight because the boss goes through the walls and into oblivion.

My suggestion to this problem would be simply to downgrade the amount of knockback that this spell gives, making it easier to attack with and also stopping this problem from occuring.
