Now you will see that the item is no longer red and can be picked up and taken.
If you split up your party, be careful they dont search you twice. Let them search you and blatently ignore the item on the ground or in their own belongings. Obviously the npc wont be too happy about you stealing their prized bucket and leaving it on the ground where they will never find it so prepare to have your goodies searched. That is why at HDGamers we took on the task of bringing you the Divinity Original Sin 2 Console Commands to improve this. Possibly, few sequels have the success of Divinity Original Sin 2 as a game that ends up offering a unique opportunity to live an incredible adventure. Stop talking to the npc and let them walk a few feet away, realizing instantly that they have lost something oh so precious. For a game to be successful, too many factors must influence that end up satisfying the demands of gamers in the world. The point is, none of your party memebers should have it on them. Better yet, put it in a chest or crate, or shove it in some other npcs pocket. Take the item you stole and put it on the ground. The npcs are smart, so you have to be careful now. Have a second party memeber, the one who isn't talking sneak outside of the victims npcs field of view. You can do this to 2 other npcs if there are several people walking around.
This prevents them from turning and seeing you steal. The statue of Lucian kills you, if you attempt the path of blood and have commited any sins like killing or stealing. Simply approach the npc you want to take from and talk to them. For those too inept to figure out the rudementary concept that is stealing and not getting caught.
