Augments are one of the most important progression systems in Purgatorio. They permanently enhance your character with stat boosts, new combat abilities, and utility effects that can dramatically improve your performance.
Some Augments increase your damage or survivability, while others replace body parts with powerful mechanical upgrades that grant unique skills. Choosing the right combination is essential, especially for tougher content.
This guide covers every Augment, how to unlock them, what they do, and which ones are worth prioritizing.
