You will have to carry a light source or use night vison racial ability or mod to see anything. It will cover lightless underground areas with complete darkness. Are you running any ENB or some darker dungeon mod? Which is better? Has anyone here tried both? Which one do you prefer? Both are compatible with COT but do pay attention when you are installing - if I recall, the mods have conflicting external lighting mods someone correct me if I am wrong.
