Praxis (DXMD)

Praxis Points are a hybrid system of skill points and augmentation canisters in Deus Ex: Mankind Divided.

At the start of the game, Adam Jensen is fitted with every augmentation he has available, and in the opening chapter, most of them is already activated. However, after Václav Koller performs a factory reset on his augmentations, Jensen has to manually reactivate his augmentations by earning experience or by utilizing Praxis kits.

As players progress through the game and gain experience points (XP), they are awarded Praxis points, which can then be used to activate dormant augmentations and upgrade active ones. Typically, it costs 2 points to activate an augmentation, and 1 point for each subsequent upgrade. Initially, players are awarded 1 Praxis point for every 5,000 experience points they collect, but after collecting enough Praxis points, the amount of experience needed gradually increases. Praxis points can also be obtained by purchasing Praxis kits from the black market or by finding them in the world.

Experience
The player is awarded different amounts of XP by completing mission objectives, indicated by the Getting things done (Main quests) and Completionist (side-quests) bonuses. However, there are also some fixed XP bonuses awarded for certain actions.

Combat Against Humans
Neutralizing a humanoid enemy typically results in XP being granted under several different titles. These titles are grouped by their criteria, namely: The combat bonuses from different categories are cumulative (so you can get both marksman and merciful soul), but bonuses from the same category are mutually exclusive.
 * Enemy Tier
 * Lethality
 * Method of Neutralization
 * Number of Targets

Enemy Tier
The amount of XP granted from this criteria depends only on the enemy's designation.

Lethality
XP is granted from this criteria only if the method of neutralization used was nonlethal.

Method of Neutralization
The title and the amount of XP granted from this criteria depends on what method the player used to neutralize that enemy. The "default" method of shooting them with bullets until they die grants no bonus.

Number of Targets
This XP is granted if the chosen method of neutralization affects multiple targets at once. Note that unlike with other criteria, this bonus is given on a per-attack, rather than a per-target basis, that is, a grenade multi-kill will only grant a single Collateral Damage bonus, whether it hit two or five targets. Also, Killing two enemy with the same shotgun blast grants no bonus.

Mechanical Enemies
Mechanical enemies only grant a single chunk of XP upon destruction, regardless of circumstances. Note that there are other ways of extracting XP from these enemies, see Remote Hacking section.

Stealth
The player gets XP bonuses for completing storyline mission objectives through stealthy measures. Not every objective awards stealth bonuses. For example, Smooth Operator bonus is not available for the objectives where no alarm-triggering equipment is present.

Hacking
For every security level there is an increasing bonus for successfully hacking a device. Additional XP bonuses may also be awarded by fulfilling certain conditions during the hacking mini-game.

Using keycodes/passwords
Using a keycode or a password to unlock a device grants a bonus corresponding to the device's security level. Note that this method is still typically inferior to hacking, since it forfeits the potential First Try and Data Extraction bonuses, not to mention the credits and hacking programs in the device's datastores.

Remote Hacking
Objects that can be manipulated by Remote Hacking belong to two groups. Environmental devices just need the first part of the Remote Hacking aug. Security devices require the Security Domination upgrade. While reactivation of these devices allows the player to hack them again, this won't result in further XP.

Exploration
By finding certain areas or taking routes other than the most obvious ones, the player is also awarded bonus XP. The first four bonuses are awarded by simply entering a certain area. The amount of XP awarded is tied to the specific area. Areas towards the end of the game tend to award the higher XP bonuses, but often require augmentations to reach.

Social
At some points in the game, the player will have to try to persuade an NPC in order to meet a certain objective. This triggers a persuasion mini-game where the CASIE mod can be of value. Sometimes, they show up as QTEs instead of a debate so it is important to not look away from the screen during certain conversations.

Praxis points
Unless one uses microtransactions to buy Praxis kits or uses mods, there is no way a player can earn the 91 Praxis kits needed to acquire all augmentations in the first playthrough (95 with the DLC exclusive augs). However, with careful planning, a player can get all augmentations using New Game +. The amount of XP needed for the next Praxis kit to be awarded depends on the player's total XP. For every 10 Praxis kits awarded from XP, the amount of XP needed for the next Praxis point goes up by 500 points (up to 7500 XP). The total XP counter resets upon entering New Game+.
 * 29 Praxis kits are available in the game through exploration, buying, and as side quest rewards (not accounting for the one-time Praxis kits from microtransactions, pre-order bonuses, DLCs, and Deus Ex GO cross-game rewards).
 * Praxis kits reappear on a New Game + so if the player is vigilant about getting as many as they can in the first playthrough, they should be able to get the rest in the second.

Maximizing XP
Tips for maximizing XP (in order of impact):
 * 1) Complete main storyline mission objectives.
 * 2) Complete side mission objectives.
 * 3) Hack every single hackable device encountered, capturing any data stores, always reloading upon the first failure.
 * 4) Explore the entire map for area bonuses and eBooks.
 * 5) Complete objectives while remaining undetected and without setting off any alarms.
 * 6) Use remote hacking on every single compatible device encountered. In case of security devices, always quit and retry after the first mistimed button press.
 * 7) Neutralize all enemies, using non-lethal augmentations. Try to take down two enemies at once whenever possible. Destroy turrets and bots, but only after used remote hacking on them.
