In Deus Ex: Human Revolution for the PC, PS3, and Xbox 360, Praxis Points are essentially like your levels in other games, and allow you to purchase augments on your augment map.
Praxis Points come naturally every 5000 XP you gain, however there are other methods to gain Praxis Points.
- Limb Clinics sell Praxis kits for 5000 credits each, so save up your credits and visit every Limb Clinic in the game for these. Check out my other guide if you need help making money.
- Praxis Kits are hidden throughout the game. Check out my other guide to locate all of the hidden Praxis Kits in the game.
- Some primary and side-quests give Praxis Kits as rewards, so make sure you check every area for all of the side-quests available.
- Get as much XP as possible to max out your Praxis Points. Hack every door, computer, safe, and alarm panel possible. Takedown every enemy you can in an area. Look for all hidden tunnels and entrances to get extra adventurer XP. Save your game before big social battles so you can keep trying for the Silver Tongue XP bonus (1000 XP).
