As with any game that has spells, the first thing that players should learn in Black Myth: Wukong is how to recover mana. As the bosses in this game have quite a large health pool, you will need to manage your resources. This is especially true for mana as this is expended when casting any of the powerful spells in the game. The blue bar under your health represents your mana. Keep an eye on the bottom left corner of the screen while in combat if you wish to properly use spells.
