At regular occasion, the Umbral Blades is thrown further than click w/ mouse.
I have determined that it probably is not lag-related:
- I have kept my mouse in 1 spot for several seconds before throwing.
- I hardly experience lag anyway.
This causes me to throw the blades behind a group of mobs instead of on/ in front.
I have not yet determined if it happens is specific areas or random. Though, in my experience, when it happens, it seems to be area bound. And it can disappear when traveling to a new area.
Edit: Even though you can see my mouse, you can see me click to walk at a certain point. The blades are thrown outside the screen.
Throwing to the right, throws them less far.
Edit 2: In my current area, they are thrown a lot further when throwing to the right.
