On this page of our guide, you will find information about the auras available in Biomutant.
Biomutant has several endings. They are dependent on the Tree-of-Life. The more you do to cure it, the better ending you will get.
If you don't heal the Tree, you will get a bad ending - you can even get one leading to the death of the world. This is the darkest ending.
Healing all the roots will get you the best possible ending.
Endings also depend on the tribes that appear in the game. You can work for them - your relationship with them will determine the ending.
Aura is a mechanic that shows your actions in the game. It is represented as Light and Dark auras. It is influenced by the actions of your character and various decisions made during the quests.
Aura affects not only the Tree-of-Life but also how others will react to you.
