I was in battle with a certain snakelike boss NPC and decided to cast a spell at him.
When i tried targeting him a message popped up telling me the target was blocked; since I had no other targets I wanted to cancel the spell, however this seemed to be impossible. The only way out of this situation seemed to be to use the auto-resolve button. Would it be possible to add a key to cancel a targeted spell like that by right-clicking or pressing escape, perhaps?
