Here are the steps to take to exploit a bug that lets you have infinite Deus Ex: Mankind Divided Praxis Kits.
• Step 1: You need to progress in Breach mode until you get a free Praxis Point for use in the main game.
• Step 2: Load your current save, go to inventory, press L2 and redeem the Praxis Point.
• Step 3: Save your game, turn off the game completely and turn it back on again.
• Step 4: Load your recent save. Go to inventory, press L2 and get another Praxis Point.
• Step 5: Repeat this as many times as you need Praxis Kits for.
Note: This glitch is working on version 1.02 of the Game
