Yeah that description probably represents their initial idea about what the skill does, but unfortunately the way AI works doesn't quite facilitate that.
Honestly, I get the impression that even though Larian pay a lot of attention to the aesthetics of their games as well as to building an interesting world with hidden objects and secrets and all that, they don't spend nearly as much time playing their own game seriously or very thoroughly - as *gamers*. It explains all the inconsistencies in the way things work, questionable mechanics, dumbed-down and half-finished systems, blatant balance issues, QoL issues, as well as the lack of original and unique character "builds".
Think about all the headache with Sir Lora and most recently the addition of the mini HP/armor bars that pop up whenever characters get hit by skills. As someone who has done my fair share of modding in video games, to me there's only one explanation for why such things happen: you don't play the game after implementing your own stuff.
