How to unlock the Pilferer achievement in ELEX - Definitive Guide
The best way to get this is find a bed and sleep until midnight, this way most of the NPC's will be asleep, press to enter sneak mode. When you look at a target it will say either unsuspecting or attentive, if it says unsuspecting then press , if the target has 2 items in his inventory then steal 1 item then exit, then repeat the process, this will count as 2 pickpockets even though it is 1 target.
You can also steal from awake targets but again make sure it says unsuspecting and make sure their are no witnesses. Make a save prior to the attempt incase you get caught. You can reload the same save and quickly get the achievement however i highly recommend using this ability throughout the game. You are able to steal rare and unique items and loads of Elex shards which will for the 100k achievement
To be able to pickpocket, you'll first need at least one point in this skill, found in the Crafting tree (or an accessory that gives you +1 to the skill). I would suggest saving before any pickpocket attempt, as a fail will turn the target hostile. Repeat 49 more times. Joining The Claws (refer to "Sewer Rat") is a good way to work on this, since their quests require pickpocketing and will help toward "Careerist" as well as getting more experience and money.
NOTE: You can save in front of any NPC, steal from them, and reload your save to do it again to quickly get this achievement done. This is easiest to do when someone is sleeping. I made a circuit of Goliet at night and got 7-10 before getting caught and reloading.
