Well, for any of you wondering about how the Infected Monsters may work, they've been confirmed to most likely be High Rank and a high point in Low Rank only so, you could kinda consider it like a new version of the Unstable Quests or the Warning Quests with a new found diffculty, especially if there is another monster wandering around making it harder.
