Praxis Kits are consumable items in multiple games in the Deus Ex series, including Deus Ex: Human Revolution, Deus Ex: The Fall and Deus Ex: Mankind Divided. Praxis Kits are used to unlock augmentations for the player character.
In the games in which they appear, Praxis Kits offer "Praxis Points," which are used to unlock augmentations. Praxis Points can alternatively be earned by in-game experience (also called "Praxis").
For game-specific information, please see the following gameplay articles:
After someone receives mechanical augmentations, it is common for many of the new features to be "locked" so that the body does not get overwhelmed and reject the augmentations. Traditionally, these abilities "unlock" themselves through prolonged usage of the augmentations, thus allowing the body to become accustomed to the new features slowly. Praxis Kits, which contain Praxis software, allow this process to be bypassed manually so as to release new features as the user wishes. This method is usually not an option for most augmentation users, but on rare occasions when a user's body accepts the augmentations with greater ease, Praxis Kits can be used to advance the process without the need for prolonged use of the augmentation.
Praxis Kits are generally considered expensive, making them difficult to obtain for most augmented users. The Tyrants offer Praxis software to their members, something that the Tyrants leader Jaron Namir call a luxury only offered to the finest mercenary agents.
In 2027, Praxis Kits are distributed mainly by LIMB clinics. David Sarif uses his influence, through generous donations, to give Adam Jensen preferred customer status. As such, Jensen can purchase Praxis Kits at LIMB clinics if he so chooses. Vera Marcovic, a doctor in Detroit's clinic stresses however, that this must be done on Adam's own free will, not Sarif's or anyone else's.
