Age of Wushu 2 Details Day/Night Cycle That Directly Influences the Gameplay
Temperature is an important factor in this game. In the day time high temperature can increase your character's thirsty level and in the night the low temperature may cause a continous decrease of HP.
There could be totally different play style in the night. For instance, wearing stealth suit at night could provide you excellent camouflage. The developer Snail Games stresses that like other cloths in the game, the stealth suit doesn't have any stat but a black cloth that makes you hard to detect at night. On the other hand, using a torch will help fight against the beasts.
