Plague's Mori - a tweak suggestion.
I think this mori could be improved by tweaking few things.
The core of what we would assume from such a killer is already in there, which is vomitting on the survivor's face. However, there are few glaring issues that breaks the feels.
First is the chanting voice. It feels too... healthy. Adding some hoarseness to her voice would be better, as she is a half walking corpse already with all that necrosis on her.
Second is the last smack on the survivor with her incense burner, just after she finishes her vomitting. How about changing that to a "heavier" vomitting but with corrupted purge instead? Thus, after initial vile purge, she quickly leans back and forward with more force, releasing the corrupted purge which is the one that kills the survivor, instead of that... burner slap.
