[Question] How does knockback upgrade on chest splitter works?

anyone tried it?

thanks

When you use it, the enemy is pushed away from you a small distance. It's not like knockdown with gale/fireball on sorcerer.

I was updating it, but already reset and not using it. My opinion is, it is hard to organize enemy with knockback.

You lose aggro and accidently make mobs reset. It is the gale force of warrior skills. This upgrade makes running elite extremely difficult in my experience. I made the poor choice of having 5/5 CS in my first build I ever used back at the level 16 cap. I never considered that some upgrades may ruin skills.
