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.

Activating all augments requires ~68 Praxis points and there are currently 21 Praxis kits noted on this wiki which means you need to get 47 points through experience. This means you need to get a total of 235000 experience to fully unlock all augments.
