Some item similar to a distress signal flare might be something to add in - the flare would shoot up, and hover overhead for something like 1 minute, illuminating a larger area than the other mist-reducing mechanics currently available. Could even have a cool down or recharge timer of 10 min. or something, has to re-power with the mists, before the player can us it again to make it more of an item that requires some thought for when to use it rather than just mindlessly spamming.
