The green mist surrounded Leo like a bubble, making it impossible to see anything other than the mist itself. Even when using Aura he was unable to discern the cultists location. Since the mist is always moving he was rendered blind in every sense.
'Dreifus, do you know what's going on here? She has two abilities and one of them was hard enough to deal with already.' Leo asked while constantly turning around to try and prevent a sneak attack.
'I'm sorry, Leo, but I know as much as you do. All I can say is that you need to be prepared for anything.' Dreifus answered.
The cultist suddenly stepped out of the Mist right behind Leo. He was able to sense her using Aura because she moved out of the mist and towards him.
He had a split second to react and turned around to face her, but halfway through his turn he was punched in the face. He saw the attack coming but he wasn't able to react to it in time.
