Skill sounds are missing along with basic attack sounds.
Spacebar dash / Dodge sound is also missing along with stronghold sounds ( Menus / Completing a Dispatch or Pet Farm )
Are you using the Korean VO DLC?
Yes I am, Did that mess up the sound with the update ?
try to disable it, verify files → launch game, select KR and see if it works. There was an issue like that sometime pre-valtan when KR voice was included in base and the dlc broke
