Sometimes when I activate Umbral Blades, it overshoots the spot where my mouse cursor is located. Not entirely sure why it does that. Also, there are times when I cannot even activate Umbral Blades no matter how many times I hit the keyboard key for it (e). I would have to change the skill that’s in that spot to another, say Cinder Strike and back to Umbral Blades before it starts working again.
I also have both of these issues with umbral blades. It just randomly stops working for no reason. Changing the skill, or putting umbral blades on another keybind fixes the issue, but it’s pretty annoying to do mid-fights.
