Spray and Pray (+dmg while moving), damage is inverted when surrounded

I am using the Constricting command viper cap and I have allocated the Spray and Pray node on my amulet.

While moving alone, the dmg increases as it should.

While moving, and while being surrounded, the dmg decreases.

Tested multiple scenarious without the varius effects and items. Same issue.

EDIT: Accuracy got reduced below 100%. NOT A BUG
