Death Sworn Katarina - E sound on dagger isn't processed
Overall sound scheme is amazing and really interesting and fits thematic. But E-sound on dagger is completely different and feels out of place.
P.S.: Sound guy you did amazing job on ult! I'm pretty sure sound change is intentional. Not sure if source is the one I think or it's just generic phantom/spirit sound. For those who doesn't understand what I'm talking about below is a reference (picture is bad I know): Kayako Saeki (Ju-On)
