Tales of Kenzera: Zau features multiple bosses located through the different main regions of the game. These bosses are Great Spirits, who Zau must help pass on to fulfill his deal with Kalunga to meet his father again. Most of these bosses are not that hard, but players playing on harder difficulties might face problems avoiding a few attacks that might result in death and having to retry. Completing all available Reflection Points and Spirit Rituals before the boss fights can be useful as they increase maximum health, give additional trinket slots, and much more.
