Blades of Mercy hitbox seems to be bugged. When fighting lost hunters and huntsmen my untransformed light attacks did zero damage if I was right beside them. I had to back away slightly to successfully hit with the light attack.

As far as i can tell the transformed version is ok, the untransformed gave me issues

If this is a design choice please change your mind, there is no reason a shortsword should have a "sweetspot" range, and even worse, do no damage when enemies are too close.
