Title may be a bit dramatic, but I wish more people knew about this.
This bug has existed for well over a year now and is affecting the combat system, making it less dynamic and easier. Before, NPCs (including allies) would use their
weapon actions and apply their
coatings all the time, now they never do. Why is only the player able to use these mechanics now? It must be a bug. Fixing this would make combat more interesting; the conditions these actions inflicted on a failed saving throw created many different situations. All of these actions also have special sounds and animations, which added some extra flair to the game.
I'm hoping Larian or a skilled modder can look into this, it might not be that difficult to fix.
