Praxis (DXHR)

Praxis Points are a hybrid system of skill points and augmentation canisters in Deus Ex: Human Revolution. As players progress through the game and collect experience, they are awarded these points, which are used to buy new augmentations and upgrade existing ones.

Typically, it costs 2 points to activate a new augmentation, and 1 point for each subsequent upgrade. Players are awarded 1 point per each 'level-up', but they can also be obtained by buying or finding Praxis Kits in the world.
