How do you /do you use control spells often or as a main tactic in your gameplay? There are a lot of very interesting control spells in the game which sound very compelling at first glance.
My experience however is as follows: There are the NPCs to whom you can apply control spells but it is not necessary/worth it, applying damage only is much faster and safer. Then there are the NPCs where control spells would be very important/beneficial, however you cannot apply them because of immunities or very low hit chances.
So I used control spells less and less over time. Except Sleep (no resist possible) in the early game stages I sometimes try Command with Shadowheart, but seldomly. I have bad experience when I try Hold Person on the more dangerous enemies, although NPCs often succeed to take my chars into Hold Person. My trials with the interesting higher level control spells went not well, usually they get resisted when needed the most. My most helpful result was in the end fight in the Act 2 Shar temple where I could change a major villain into a sheep for some time, which granted me survival. But that's a seldom exception.
I never played DnD, is it similar in the tabletop? What are the spells you use the most?
