Currently on P1999 I've found 3 spells (and I assume the entire line for poison/disease) have incorrect sound effects.
-Flash of Light (had a fear like sound effect on live, schhhhweeeeooooo)
-Poison dot spells
-Disease dot spells
Here is a video I found which I think is emulated but is using the correct sound effects
